1. General introduction

3D Laser Scanning is using a 3D scanner to scan an object or environment in the real world to collect data about the shape and possibly properties of the object.

The purpose of a 3D scanner is usually to create a 3D model. This 3D model consists of point clouds of geometric patterns on the object’s surface. These points can then be used to extrapolate the object’s shape (a process called Reconstruction).

2. Application of 3D Laser Scanning in various fields

3D laser scanning is widely used in many fields and industries with different purposes and needs. Commonly used fields include mold design and processing, architecture and sculpture, manufacturing and healthcare, shipbuilding, etc.

For heavy industries such as shipbuilding, 3D scanners play an important role in ship design, providing optimization solutions and saving costs and time.

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

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.
