The function of CNC automatic drilling machine and its mechanical advantages
The point position control of the CNC automatic drilling machine is mainly used for the hole processing of parts, such as drilling, center drilling positioning, countersinking, reaming, reaming and boring processing operations. The continuous control function can mill the curved surfaces of the parts through circular interpolation, linear interpolation or cyclic curve interpolation of the CNC drilling and milling machine. Next, let’s talk about the function and equipment of the CNC drilling and milling machine. What are the advantages.
If the tool radius compensation performance is directly programmed according to the workpiece appearance line, the essential appearance line will be larger by the tool radius value when processing the inner and outer appearance of the workpiece; when the workpiece appearance is processed, the essential appearance line will be smaller by the tool radius value. Using the tool radius compensation method, the CNC drilling and milling machine system automatically calculates the tool center trajectory, so that the tool center deviates from the appearance of the workpiece by a tool radius value, thereby processing an appearance suitable for the requirements of the drawing.
Using the performance of tool radius compensation to modify the tool radius compensation amount, it can also compensate the tool wear amount and machining deviation, and complete the rough machining and finishing of the workpiece.
Tool length compensation performance The compensation amount of the modified tool length can compensate the length deviation value after the tool is changed, and it can also modify the plane address of the cutting process to control the axial positioning accuracy of the tool.
Invariable cycle processing performance The use of invariable cycle processing instructions can simplify the processing procedure and reduce the workload of programming.
Subroutine performance. If the processing work piece has the same or similar department, write it into a subroutine and call it by the main program, which simplifies the program structure. The performance of the subprogram is used to modularize the processing program, and several modules are distributed according to the working procedures of the processing process. The subprograms are written as farewells and called by the main program to complete the processing of the workpiece. This kind of modular program is convenient for processing debugging and optimizing processing technology.
