1. General introduction to automatic bar feeding using a Gantry robot

Currently, in the production, assembly, and product quality inspection in the industry in general and the mechanical manufacturing industry in particular, everything is all developing according to the rising trend of automation. To ensure a stable production process, it is necessary to supply workpieces accurately in time and space and continuously in cycles in a systematic and highly reliable manner. Therefore, the bar feeding process is one of the urgent requirements that need to be researched and resolved in automatic production systems with the aim of improving productivity, labor quality, and machine usage efficiency.

In addition to robotic arms, robots fixed above the surface are also widely used in these systems. Gantry robots often appear in mass production lines, with large productivity because they are not limited by operating area.

In mechanical processing machines, to optimize production and increase productivity and product quality, there will be different bar feeding methods for each type of product. In particular, for CNC lathes, there are two main automatic bar feeding methods: Bar feeder and Gantry robot. In this topic, we would like to introduce the Gantry robot bar feeding solution.

2. Structure and technical specifications

2.1 Structure

The general structure of the system includes Guide rail system – transmission, signal control cable, control cabinet and industrial computer, sensors, drive motor, and robot gripper.

2.2 Main technical parameters

3. Characteristics, advantages, and main components of the system

3.1 Characteristics

• The system is used to supply each workpiece during the machining process with a fixed size (each product has a separate gripper structure). Compressed air is an indispensable element in the equipment’s requirements for the system to operate smoothly and accurately. Compressed air needs to be dry, clean, oil-free, and water-free. Short bar feeding time helps increase machining output.
• Gantry Robot solves both problems: unlimited scale and movement area, as well as space-saving, are the two biggest characteristics of Gantry Robots that are widely used in automation systems.
• In addition, simple design, reasonable cost, and easy scalability due to the modular structure are additional features that add competitive strength to Gantry Robots.

3.2 Advantages

• Optimally utilize up to 96% of installation space to perform tasks related to pumping and applying glue, saving space and simple design.
• Easily scale in all 3 dimensions: X, Y, and Z.
• Due to its sturdy yet compact structure, the Gantry robot operates accurately through many iterations.
• Modular design, therefore, has options suitable for each user’s unique application, saving maintenance and periodic inspection costs.
• Combine with image sensor modules in some product lines to increase accuracy, post-machining inspection, and NG product rejection.

3.3. Main components of the system

a. KR-C4 control system

• The KR C4 controller is a pioneer in automation.
• It reduces your costs for integration, maintenance, and servicing. At the same time, the long-term efficiency and flexibility of the systems are increased – thanks to industry standards.
• KR C4 software architecture integrates Robot Control, PLC Control, Motion Control (e.g., KUKA.CNC), and Safety Control. All controllers share a database and infrastructure.
• Higher efficiency in CNC machining. The KUKA.CNC control option allows direct programming and operation of the KUKA robot via G-code. It can handle even the most complex programs from CAD/CAM systems and provides the highest accuracy due to CNC toolpath simulation. This dramatically simplifies the integration of the robot into an existing CNC environment.

b. Smart PAD controller

• Whether you’re a programming novice or an expert, the KUKA smart PDA will quickly get you to your goals because it offers suitable programming options for every requirement.
• A single dashboard to perform the most diverse tasks reliably.
• KUKA.KRL – advanced robot programming language. “KUKA Language Robotics” is a globally standard programming language. It is easy to learn and fits perfectly with KUKA robots’ diverse options.
• The intuitive KUKA smartPAD can be used to create complex and customized programs for robot movements and tasks in a variety of applications – both online and offline.
• Simple and efficient: programming with inline forms, forms to program tasks and movements quickly, without errors. They can be ordered via the menu and are available as standard. This simplifies the programming of RoboTeams with up to six synchronized robots.
• Customer-defined program modules. Upon customer request, KUKA integrators can expand the library of available KUKA inline templates. This leads to the creation of special applications that can be easily programmed for recurring tasks.
• Competitive advantage for system integrators: specially developed inline forms enable unique solutions that are optimally suited to the companies that use them.

1. General introduction

With the vigorous development of the technology industry in general and the mechanical technology industry in particular, advanced equipment is designed to improve and replace old technologies. In the mechanical industry, many machines are designed and manufactured to produce specific parts that require high precision, such as parts in the medical, space, and aviation sectors, etc. Among them, it is impossible not to mention CNC machines. CNC machines were invented to improve, and special features were added to help us reduce processing time, increase work productivity, and achieve high accuracy.

The power of advanced technology on each CNC machine ensures safety for people and equipment, but collisions during processing cannot be avoided, affecting the economy, equipment, and time. To limit those collisions, OKUMA – a leading CNC machine manufacturer in mechanical equipment technology worldwide – has researched and developed a Collision Avoidance System (CAS).

2. Features

* Allow the operator to focus on part fabrication

CAS prevents collisions in automatic or manual mode, providing protection that does not pose a risk to equipment and bringing peace of mind to the operator.

The figure below is the machining process between simulation and actual machining mode.

* Prevent collisions when in automatic machining mode

The NC program will be read first, the axial movement commands will be checked for collisions with zero zero, and the tool compensation value will be set in the NC file. Temporarily stop moving the axis before a collision occurs.

* Avoid collisions in manual mode

It is especially useful for operators setting up work, bringing confidence without worrying about collisions, and preparing for faster processing.

* Realistic simulation of the workpiece-cutting process

Accurately displayed and checked for collisions of workpiece shapes during machining.

3. Safety and advanced features

Simplify information entry and easy modeling.

* Machine (Settings completed)

Registered 3D model of the machine.

Automatically choose settings to boot.

* Chuck selection (Fixed)

Store 3D models of standard chucks.

Input selection from 3D models.

* Cutting tool selections

Store standard information on cutting tools.

Input selection from the 3D model.

Users can also create their readable 3D (STL) information and models.

* Enter shape information

Enter basic information about the size of the cutting workpieces.

End-user’s 3D STL code can be accepted.

4. Examples

* Avoid collisions during rotation and movement of the turret

Avoid unexpected collisions with long-cutting tools when rotating and moving the turret. Users can focus on machining without worrying about collisions.

* Check for collisions during the process of shaping soft jaws

Since the chuck is fixed, CAS cannot be used during the machining to define the soft jaw. However, by defining the jaw shape as a blank material code, CAS can be used.

5. Caution

The Collision Avoidance System (CAS) is a detection system based on 3D models of machine parts, cutting tools, jigs, and blanks stored in the OSP. Therefore, if you enter relevant information other than the actual size, CAS will not accurately detect the possibility of collision. In some cases, devices or movements are subject to limited collision detection.

1. General introduction

The reverse engineering system’s purpose is summarized as follows:

From the existing PCB, its image is inserted into the computer through the scanner. The software system used by expert engineers will convert each part from images of each PCB layer to Gerber files, Drill files, Assembly Data, Virtual PCB, Nestist, and principle circuits.

2. Operating principles and procedures

The process to make a reverse-engineered product from a given PCB:

• Create a BOM file: Create data about all components mounted on the board, their fundamental parameters, the manufacturer, and where the components can be purchased.
• Taking photos of the PCB: Taking pictures of the PCB will create input data for data processing software. There are two ways a PCB can be taken picture as input data:

• • Destructive method: It is a pressure spray system with microscopic glass particles of 0.3 microns in size under high pressure to clean the PCB surface and peel off layers of multilayer PCB. After peeling off each layer, high-resolution photography will be taken as input data.
  • Non-destructive method: X-ray imaging system. With support from the X-ray machine, tomographic images of each multilayer PCB layer will be fed directly into the processing software. The PCB is entirely intact after the reverse engineering process.
• Create Gerber file from input data: Gerber file is a type of file with complete information about printed circuit layers.
• Create Drill file: A type of file containing information about drilling holes in printed circuits from the top to the last layer.

Note: With data from Gerber and Drill files, users can send that information to printed circuit manufacturers and thoroughly test the PCB that needs to be reverse-engineered.

• Create PCB images to see the entire circuit board
• Create Netlist file
• Create Schematics file: principle diagram.

2. Structure and technical specifications

2.1. Structure

The general structure of the system is as follows:

For each different manufacturer of automatic bar feeding systems, the machine structure will be different, but in general, an automatic bar feeding system will have the structure as above. For convenience, the system’s design needs to be quickly customized according to production requirements.

2.2. Main technical parameters

3. System characteristics and features

3.1. Characteristics

The system is used to bar feeders within a specific diameter range with predetermined length dimensions. Compressed air is an indispensable element in the equipment’s requirements for the system to operate smoothly and accurately. Compressed air needs to be dry, clean, oil-free, and water-free. Short bar feeding time helps increase machining output. In addition, the bar rack is designed to hold a lot of bar blanks, helping to reduce the time workers have to feed the bar blanks to the machine.

3.2. System features

For the machine to operate safely and productively and bring high efficiency in manufacturing and production, the device has the following specific features:

a. Protection sensors outside the system

• Sensor type: Vibration sensor.
• The sensor is used to protect the device when encountering unexpected problems such as not being fixed to the ground, vibrations occurring, or a strong impact on the system.

b. Push rod – customized according to bar stock diameter

• For each different bar diameter range in machining, a push bar of corresponding size is required.
• Changing and installing push rods is simple and easy to do, meeting production requirements.
• The push rod must be straight and not warped so that during the feeding process, it can maintain relative concentricity with the main axis of the machine.

c. Stopping finger

• When the bar stock is in a state waiting for processing, a stopping finger is required to prevent other bar billets from being pushed into the system while the system is working.
• The stopping finger is designed for all bars within the working diameter range.

d. Safety sensors in the system

• Sensor type: Proximity sensor
• Used to protect while the system is working, minimizing risks in actual production situations such as billets falling into the system, billets being too long compared to the working capacity of the device, clamping damaged workpiece, etc.

4. System applications

• Used to feed round bar billets to CNC lathes.
• Increase labor productivity, reduce product costs, and increase competitiveness.
• Suitable for many CNC lathes, simple installation, easy to operate.

Solution Overview

Radar technology is a critical capability for flight safety, precision navigation, space applications, and more. To meet future electromagnetic spectral operation requirements, modern radars are increasingly being designed to be frequency agile with cognitive and multi-modes while utilizing ultra-broadband active electronically scanned arrays (AESA) to dynamically adapt to the ever-changing electromagnetic spectrum. Additionally, modern radars are increasingly being designed with the goal of improving EW resilience and low probability of intercept (LPI) with multi-function and perception capabilities, Radar, EW and Comms.

Due to the increased complexity and cost of designs, finding issues before open-air range test has never been more important. Today, radar engineers are leveraging powerful modeling and simulation tools to digitally test systems prior to implementation. Most leading Radar Manufacturers leverage Hardware in the Loop integration testing to minimize risk and find problems early in the design cycle.

1. General introduction

Antenna testing & measurement is a very common need in the telecommunications industry in general and high frequency in particular. This is one of the basic tasks in antenna theory. Antenna theory cannot be completed if the antenna under test (AUT) measurement cannot be achieved as desired. Basically, when doing this work, we want to test the basic theoretical parameters of the antenna such as gain, efficiency, impedance or VSWR, bandwidth, and polarization of the antenna. New technology combined with data processing software can also draw the antenna radiation pattern characterization diagram.

2. Antenna transmission theory

The antenna’s transmission space is divided into 3 areas: reactive, near-field and far-field.

The spatial region with a distance greater than 2D2/λ radiation is called the far-field region, in which D is the maximum length of the antenna. In this region, the beam shape does not change with distance; in other words, the measured radiation pattern characterization is determined.

The spatial region limited from λ to 2D2/ λ, is called the near-field region. The radiation pattern characterization of the antenna in this spatial region changes with distance, especially the shape of the beams. However, we can determine the equivalent radiation pattern characterization as the far-field region by mathematical transformations from near to far-field.

The spatial region limited from the reflecting surface of the antenna to a distance λ (1 times the wavelength) is called the ultra-near field region. In this space, the antenna’s radiation has a negative impact on the antenna itself. Therefore, the signal in this region is very noisy, unstable, and has many different beam shapes that change with distance. In other words, it is challenging to determine the antenna radiation pattern in this case.

For example, with a 1m diameter antenna operating at 10 GHz (λ = 3cm), the near-field region will extend to about 2/.03 = 66m.

Due to the changing characteristics of the signal wave according to the area and distance of the antenna, antenna test and measurement methods are also divided into different ways. In fact, antennas are the main elements used for long-distance communications, when wired transmission is difficult to meet the requirements. Therefore, testing antennas in the far-field region is the most necessary and realistic task. However, setting up an antenna test, measurement, and evaluation system in this region is not easy. Antenna test and measurement methods are divided into two types, which are near-field and far-field. With the near-field measurement method, the measuring distance is relatively small, so usually, the system can be explicitly installed in the home, also known as a measuring chamber or anechoic chamber. Testing in far-field regions often involves vast distances, especially large-sized, high-frequency antennas such as antennas of radar stations, aircraft antennas, antennas in high-frequency receiver and transmitter systems, etc.

3. General requirements and specifications

3.1. Required equipment for antenna testing and measurement

When using plane waves to test the antenna under test (AUT), we can consider using a source (transmitting) antenna with known characteristics and radiation patterns, affecting the antenna in the way of random fields. Required equipment includes the following:

• Transmitting antenna and signal generator: This antenna has known radiation used to transmit to the AUT.
• Receiver system: this part determines how much power the AUT receives.
• A positioning system: This system rotates the AUT, combined with the transmitting (source) antenna, giving a radiation curve as a function of the rotation angle.

The source antenna must ensure good operation at the frequency to be tested. This antenna must be polarized in advance and have a bandwidth suitable for the AUT antenna measurement range. The source antenna is usually a horn antenna or a dipole antenna with a parabolic reflecting surface.

The transmitter ensures stable power generation according to calculations. The output frequency must also be accurate and adjustable (ability to select and change the frequency range) and reasonably stable (low-frequency drift).

The receiver will be responsible for receiving and determining the power level of the signal received from the AUT. This receiver can be supplemented with low noise amplifiers to measure low power levels and extend the measurement range of the system.

The positioning system is used to steer and control the direction of the AUT. The essence of this method is to calculate the radiation graph of the AUT based on the results obtained from a function of the rotation angle value (e.g., spherical coordinates). The system will rotate the AUT in different directions and angles so that the transmitting antenna (source) can broadcast directly from many directions. Usually, the AUT will be turned and scanned 360 degrees in a spherical shape.

3.2. Measurement space

After having the measuring equipment, setting up a space to perform the antenna test is necessary. In theory, a measurement system can be deployed with such devices anywhere. However, in reality, this needs to be selected and calculated in detail because the antenna measurement requires a space unaffected by any signal or noise during the measurement process. Ideally, we need to perform this measurement in a space without any unwanted signal reflections or emissions during the measurement process. However, this is currently impossible. Therefore, the current solution chosen is to build a closed space, blocking all types of electromagnetic waves from unwanted radiation sources and making it capable of eliminating electromagnetic reflections in the implementation area. measurement.

It is called the Anechoic Chamber or Electromagnetic Wave Shielding Chamber.

It is easy to see that this method is very suitable for the near-field antenna measurement method because the measuring chamber area can only be built to a specific limit; it cannot be expanded too large, and it will encounter construction problems: construction and costs. Far-field measurement chambers are also deployed but are not as common as near-field.

* Anechoic Chamber (Electromagnetic Wave Shielding Chamber)

The AUT and receiving antenna are placed apart in the near field, the AUT is placed on a mount that can rotate along the AZ/EL (azimuth/ elevation) axes. The receiving antenna is also capable of moving in the plane along the X, Y and Z axes. The relative motion between the receiving antenna and the AUT results in different scanning methods: planar, cylindrical and spherical scanning.

When to use the measuring chamber?

When the need for accurate measurement and evaluation of the antenna is necessary, building a measurement chamber requires space, equipment, materials, and appropriate budget investment when the antenna to be measured is small in size, and the measurement method used is near-field measurement. The measuring chamber is also more convenient for the operator, monitoring the measurement process, and is not much affected by the weather.

• Planar scanning:

The near-field measurement arrangement for performing flat scanning is depicted in the figure of the sampling step ∆x = ∆y = λ/2. The AUT is fixed. In transmit mode, the probe is moved to scan and sample step by step ∆x, ∆y, up – down/horizontal, on a plane (x,y) parallel to the AUT aperture plane, away from the AUT aperture. from 3λ to 10λ.

The receiving field data will be received by the probe, recorded and then transformed and the probe will be compensated to obtain the far-field emission pattern of the AUT. This is the simplest type of measurement, both in terms of positioning equipment (positioner) and processing software (processing software). The main error encountered in planar measurements is due to the scanning surface not being infinite, leading to errors in the sidelobe structure and limitations in azimuth (truncation error).

This method is often used to measure directional antennas, with G > 15 dBi, the maximum measured azimuth angle is about < ±70 degrees. Depending on the size of the measurement room, array antennas or reflector antennas can be measured.

• Cylindrical scanning:

The AUT rotates around the z-axis in ∆φ steps while the probe moves up and down parallel to the z-axis in ∆z steps, creating a scanning journey equivalent to a cylindrical surface surrounding the AUT. The distance between the probe rack and the AUT is chosen to avoid interaction between the AUT and the probe. The length of the cylinder determines the truncation error. The parameters of interest in this method are ∆z = λ/2, ∆φ = λ/2 R; where R is the radius of the cylinder.

This method is suitable for measuring antennas with wide beams (azimuth) with apertures in the range of less than 1.5m.

• Spherical scanning:

There are 2 methods of scanning:

The AUT rotates around the z-axis with steps ∆φ, the probe rotates in a circular orbit around the AUT with steps ∆θ, and the probe remains stationary at a point on the z-axis of the AUT.

The AUT rotates simultaneously around the z-axis and the θ axis in steps ∆φ and ∆θ. The scanning trajectory of the probe is equivalent to that of a sphere of radius R. The scanning angular resolution is ∆φ = ∆θ = λ/2 R rad.

** Advantages of the solution:

• Reasonable cost, simple testing.
• Easy to track, not affected by the weather.

** Disadvantages of the solution

• Request to build or select a space to be an anechoic chamber.

The measurement time is quite long, but the company has data processing solutions that have also optimized the processing and reduced the measurement time.

*Outdoor measuring site:

When implementing the outdoor measurement plan, the AUT antenna is installed on a test positioner placed on the top of the tower (or roof, pedestal outside the system equipment control room). The end of the receiver line (the internal oscillator) is usually located below the positioner, with the mixer connected directly to the port of the AUT. The system only requires a single high-frequency path to the positioner, simplifying system setup and operation. The system can be equipped with additional outdoor screens to protect the internal oscillator from weather and extreme temperatures. Multi-port antennas can perform simultaneous measurements using a multiplexer installed before the mixer. The receiver and transmitter positions are controlled through the receiver interface.

The transmitting antenna (source) is placed opposite the receiving tower, ensuring the receiving side receives the signal. The signal source is placed near the transmitting antenna to reduce signal loss. Control communication between the transmitter and receiver sides is performed by fiber optic cable or Ethernet.

When to build an outdoor measuring site?

Outdoor measuring sites require a more complex and long-term deployment process. Of course, the efficiency of the measurement is also greatly improved, especially the practicality of the measurement, because the outdoor measurement system can measure many types of AUT antennas in different measurement ranges and sizes, huge antennas such as radar antennas, phased array antennas… In addition, outdoor measurement sites also provide more realistic results due to the influence of environmental factors during the measurement process.

Typical parameters:

• Frequency range: full frequency range supported by high-frequency devices
• Control system: stepper motor or servo motor
• Maximum antenna load: flexible, depending on requirements
• Position resolution: 0.01°
• Rotation speed: 40°/s
• Measuring system: measuring control workstation with LCD control screen
• Motor cable: Quick-connect; 40′ (12.2m)
• High frequency cable: ~6.1m; DC-18 GHz; SMA or N connection

Deployment plan

The reference antenna (source antenna) and the AUT antenna are arranged on high towers, ensuring the following distance and height requirements:

• Distance between reference antennas and AUT: r > 2D²/λ;
• Height of hAUT towers = hAS > 4D (where D is the vertical dimension of the AUT) to ensure reflections are minimized.
• Dimension d of reference antenna: d < 0.37 λR/D

To ensure amplitude taper at the AUT surface and reflected noise due to the environment, the first null point is required to be lower than the base of the antenna. If you want to reduce reflections further, you can use range fences.

** Advantages of the solution

• Wide measuring range, can measure many types of antennas.
• Measurements are performed quickly, and the measurement results are very close to reality.
• High professionalism and excellent reliability of results.

** Disadvantages of the solution

• Large cost and lengthy implementation time to ensure technical and project quality.
• Physically affected by weather and climate; however, there are solutions to protect the project.

Drone-based antenna radiation pattern characterization for low-frequency range antennas (the frequency range of naval ship antennas) fixed on complex systems is challenging when performing field measurements in remote areas, especially for antennas with large sizes and weights. Therefore, the idea of using unmanned aerial vehicles (UAVs) to integrate automatic data collection and processing was invented.

However, in terms of investment efficiency, using a drone model is not an economically effective solution because the cost of a drone is too high. Based on the need to build pattern characterization for fixed antennas on naval ships with a low budget, leading experts in the field of antenna measurement and quality assessment from Anritsu have come up with a solution using a handheld spectrum analyzer with minimal size and weight mounted on a drone, collecting data, then processing it with software to reduce costs and improve investment efficiency significantly.

Technical solution

• Working frequency range: up to 110 GHz
• Types of antennas that can be measured: phased network antennas, parabolic antennas, etc.
• The size of the largest open surface of the antenna needs to be measured in the azimuth plane: up to 16m
• The size of the largest open surface of the antenna needs to be measured according to the abtuse angle plane: up to 4m
• Antenna gain coefficient to be measured: The maximum that can be measured is 50 dB
• Side beamwidth level of the antenna to be measured: The maximum that can be measured is 45 dB
• Polarization types: vertical, horizontal
• Directional diagram of the antenna to be measured in azimuth: 360 degrees
• Directional diagram of the antenna to be measured according to the abtuse angle: fixed

With the above features, antenna parameters that can be measured and evaluated include:

• 2D and 3D diagrams of the azimuth and elevation angle planes
• E, H plane polarization
• Antenna gain coefficient, directivity
• Maximum radiation angle

Basic measuring principles

Description of the basic measurement method using the far field method:

From the requirements for testing radar antennas installed on naval ships, with complex connections, large size and weight, disassembly is completely difficult, further requiring a system. Far-field measurements are complicated and cumbersome.

The antenna to be measured will be fixed on the ship or mounting system.

The receiving antenna will be installed on the control aircraft to perform testing at a distance far enough to ensure the pah properties of the signal at the contact surface of the irradiated antenna.

To ensure measurement accuracy, the distance between the antenna to be measured and the transmitting antenna must ensure:

Distance ≥ 2D^2/l

Where: D is the open-face size of the antenna

l is the wavelength of the antenna to be measured

Structure and composition of measuring solution

The diagram of the antenna solution using the far-field measurement method, giving the diagram is described as follows:

– Signal collection part:

– Power supply to the receiver:

– Total volume of the receiver

Advantages of the solution

• Using drones and handheld spectrum analyzers has significantly reduced the size of the system, reduced costs, and increased cost efficiency
• The receiver has a wide working range, is high quality, suitable for many types of antennas, and produces accurate results
• Completely eliminate the need to disassemble and move large antennas when performing measurements
• Eliminate the influence of terrain on measurements
• Because there is no reference antenna system to align the phase, this solution is only suitable for measuring antenna radiation reduction.

Limitations of the solution:

• Drones have limited battery life, making it challenging to perform long, continuous measurements

The solution does not meet the requirements for measurements that require high accuracy. However, regarding investment efficiency and testing needs, this solution suits projects with low budgets.
