Abstract

The invention discloses a helical milling method, including the steps of setting a plurality of feature parameters for one or more milling features of workpieces to be subjected to helical milling; judging whether values are assigned to local variables corresponding to all the feature parameters one by one; assigning a value to the local variable which is judged as not assigned yet according to aglobal variable corresponding to the local variable; judging the machining types of helical milling of all the workpieces one by one based on the local variables with assigned values; and performing the helical milling operation correspondingly according to the judged machining types. The method disclosed by the embodiment of the invention can not only improve the efficiency of helical milling ofworkpieces, but also improve the qualified rate of workpiece machining.

Description

technical field [0001] The invention relates to the technical field of numerical control machining of machine tools, in particular to a method for helical milling. Background technique [0002] With the continuous progress of CNC machining technology of machine tools, the operation of helical milling for holes, shafts and other features is increasing. At present, the method of helical milling is mainly realized by programming macro programs. [0003] The method of compiling macro programs has the following disadvantages: 1. The readability of the program is poor, and the user needs to ponder over and over again to understand the programmer's intention; 2. The programming is prone to errors, and a complete helical milling macro program involves multiple variables. Improper citation will cause the milling path not to meet expectations; 3. Poor portability, the macro program can only be used for a specific hole and axis, if there are multiple holes and axis features, the progr...
