What ls G Code?

G-code is the most common CNc programming language used in CAM (Computer Aided Manufacturing) software tocontrol automatic machine tools, which is also known as RS-274.

G code is the instruction in the CNC program, which is referred to as the G command. Using G code can realize rapidpositioning, reverse circular interpolaion, parallel circular interpolation, intermediate point circular interpolation, radiusprogramming, and jump processing for CNC machining.

What ls G-Code Interpreter?

The G code interpreter is an important module of the CNC controller software, CNc Machines usualy use G codes todescribe the machining information of the machine tool, such as the tool path, the selection of coordinates, and theopening of the coolant. it is the main function of the G-code interpreter to interpret G-codes into data blocks that can berecoanized by the CNC system. The openness of the G-code interpreter is also a problem that must be considered in thedesian and implementation.

In the G-code interpreter, keyword decomposition of G-code is the skeleton, and grouping of code is the basis for syntaxchecking.

Ihe G code interpreter reads the G code, interprets it into G intermediate code, and then undergoes interpolation anoposition control processing, and finally the output module cals the driver to output it to the POl or ISA card of a CNomachine.
