Abstract

The invention discloses a method for checking the precision of a numerical control program, and belongs to the field of numerical control programs. The method comprises the following steps that S1) apart geometric model is established, a sprocket wheel part model is created, and serves as a target part of processing simulated programming; S2) a processing technology is analyzed, and a processingscheme is drafted; S3) pretreatment before processing is carried out by setting related parameters and workpiece related information of a numerical control machine tool before processing; S4) post-treatment after processing is carried out, a post-treatment file customized for the machine tool is generated directly, and codes of an axial numerical control program supporting a numerical control system are output; and S5) processing is simulated by program verification. The checking method is more scientific and reasonable, machine tool program codes suitable for the operating system can be obtained by processing simulation of the part and output of a tool position source file, the programming checking time is shortened, and the machining quality and benefit are both improved.

Description

technical field [0001] The invention relates to the field of numerical control programs, in particular to a method for checking the accuracy of numerical control programs. Background technique [0002] With the rapid development of computers and software, the calculation of complex data in NC machining can be realized, and the automatic programming software system is connected with NC machine tool processing.
