G Code

Every cnc program is a sequence of many cnc program blocks which are written together to form a complete tool-path for one or many tools. This tool-path tells cnc machine how a cnc machinist want his component be machined.

These cnc program blocks mainly consist of G code and tool positioning data (axis movements).

G Code in a broader way are instructions to cnc machines.

Every G-code has such a vast functionality and sequence of operation associated with it that every G-code might take a full length tutorial to explain it’s working.
