Tool length is stored as an offset code and used to zero the Z-axis before the end mill is lowered 3/4 in. Compensation is used in the program both for tool diameter and tool length. end mill is stored in position 1 in the tool turret.

Codes are based on Fanuc controllers and this same program on another controller would probably look similar but might have minor differences. The following example program could be used to mill a 6 in.

For more information about G-code and M code, please refer to other related articles in this series listed at the end of this article. This article presents a simple CNC program to demonstrate the typical structure and workings of G-code. Through various combinations of G-code, M-code, and other lettered commands, a CNC machine is told to change tools, start spindles, move cutting tools, etc.

CNC programs direct computer-controlled lathes and mills РІР‚вЂњ usually referred to as turning and machining centers РІР‚вЂњ in the machining of parts.
