To ensure safety and increase work efficiency, the collision avoidance system when processing CNC machines is researched and developed to meet the requirements of industries requiring high precision.
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.
