Description

technical field [0001] The invention relates to a numerical control machining method, in particular to a numerical control machining method of multi-type combined hole groups. Background technique [0002] CNC machine tools often need to process some single holes, regular group holes, and multi-type regular group hole combinations, such as processing matrix-shaped group holes on steel plates, processing circular group holes on flanges or its rectangular holes and Hole groups formed by a combination of circular hole groups, etc. In the NC machining process, the operator needs to set the program in the NC equipment according to the process. If manual programming is used, for the programming process of group holes and holes, it is necessary to calculate the coordinate value of each node, which not only requires a large amount of calculation, but also Low efficiency, error-prone, poor machining accuracy, and poor quality; if programming by calling subroutines, first write the s...

In the NC machining process, the operator needs to set the program in the NC equipment according to the process. If manual programming is used, for the programming process of group holes and holes, it is necessary to calculate the coordinate value of each node, which not only requires a large amount of calculation, but also Low efficiency, error-prone, poor machining accuracy, and poor quality; if programming by calling subroutines, first write the subroutines, and then use the main program to call the subroutines for processing. It needs multiple calls to complete, which requires high programming ability of the operator; if automatic programming ...
