Basics of G Code Programming 231

Basics of G Code Programming provides a comprehensive introduction to G code programming. Programmers use G codes to create part programs, which direct CNC machines to create a part. Part programs consist of blocks, which contain words that are a combination of a letter address and a numerical value. N codes name or title a program block. G codes describe the operation that the machine will perform. X, Y, and Z codes determine the cutting operation location. F and S codes set the feed and speed, T codes signal the correct cutting tool, and M codes complete other miscellaneous functions. Programmers often rely on computer-assisted programming software to efficiently create part programs. However, to create or edit a part program for a CNC machine, a programmer must understand the different codes in G code programming and what they do. After taking this class, users should be able to describe how G code programming is used to create a part program.
