Special motion control method for electric discharge machine based on G-code

Abstract

The invention discloses a special motion control method for an electric discharge machine based on a G-code. The special motion control method comprises the following steps: a main control module receives the G code input by a user; the main control module reads a G-code file and runs the G-code file; the G-code file is pre-compiled and checked, if yes, a step 5 is executed, and if not, the errortype and the error position are prompted, and an alarm is given out; the G-code is started to be decoded after being pre-compiled; if code processing subprograms do not meet a G-code running requirement, the error type and the error position are prompted, and an alarm is given out; and all line codes of the G-code are identified, the types of all code processing subprograms are identified, decoding the G-code is finished, and the program is ended. Before the G-code runs, the G-code can be checked in advance, the correct rate of the G-code is improved, and uncontrollable errors caused by directrunning of the G-code during running of the electric discharge machine are prevented.

Description

technical field [0001] The invention relates to the technical field of electric discharge forming machine systems, in particular to a special motion control method for electric discharge forming machines based on G codes. Background technique [0002] G code (G-code, also known as RS-274), is the most widely used numerical control (numerical control) programming language, there are multiple versions, mainly used in computer-aided manufacturing to control automatic machine tools. G-code is also sometimes referred to as the G programming language. The G code interpreter is an important module of the all-software CNC system. CNC machine tools usually use G code to describe the machining information of the machine tool, such as tool path, coordinate selection, coolant opening, etc. Interpreting G code as a data block that can be recognized by the CNC system is the main function of the G code interpreter. The openness of the G code interpreter is also a problem that must be con...

Problems solved by technology

[0003] Due to the variety of G code programming, it is difficult to find out whether there is an error in the G code before decoding the G code, resulting in the risk of control loss of control of the EDM machine using the G code during operation, and the length of the G code code Extremely long, once the code has errors, it takes a lot of time to check and verify the code
