Due to the different CNC -controlled CNC systems, there are certain differences in the definition and function of the instructions used, but their basic functions and programming methods are the same.

The main function of CNC milling machine

1) The point control of the point control function CNC milling machine is mainly used for the hole processing of the workpiece, such as the central drilling, drilling, expansion, pores, pores, reh holes, and pores.

2) Continuous control functions The planes and surfaces of the workpiece of the workpiece through the straight -line interpolation, arc interpolation or complex curve interpolation of CNC milling machines. Machining Center   

3) The knife radius compensation function If it is programmed directly according to the contour line of the workpiece, when the contour of the workpiece is processed, the actual contour line will have a large diameter value of the tool; when the contour of the workpiece is processed, the actual contour line is smaller. Using the method of compensation for the radius of the tool, the CNC system automatically calculates the center trajectory of the knife appliance, so that the center of the knife is deviated from the contour of the workpiece, a tool radius value is processed, so as to process the outline that meets the requirements of the drawing. Use the function of compensation for the radius of the tool to change the amount of compensation for the radius of the tool. It can also compensate the amount of wear and processing errors to achieve rough processing and precision processing of the workpiece.

4) The length of the tool length compensation function changes the amount of compensation of the tool length. It can compensate the length deviation of the length of the knife after changing the knife. It can also change the plane position of the cutting processing, control the axial positioning accuracy of the tool. Machining Center  

5) Fixed circulation processing instructions for fixed circulation processing functions can simplify processing procedures and reduce programming workload. 6) The subroutine function If the shape of the processing workpiece is the same or similar, it is written as a subroutine and called it by the main program. This simplifies the program structure. Quote the function of the subroutine to modular the processing program. It is divided into several modules according to the process of the processing process, and the subroutines are compiled separately, which is called by the main program to complete the processing of the workpiece. This modular program is easy to process and debug, and optimize the processing process.

7) Special functions are configured with imitation software and imitation devices on CNC milling machines, and use sensors to scan and collect data on the physical objects. After data processing, the NC program is automatically generated, and the imitation processing of the workpiece is realized to achieve reverse processing engineering. In short, after the processing center is configured with certain software and hardware, it can expand the function of the CNC milling machine.
