G Code is a special programming language that is interpreted by Computer Numerical Control (CNC) machines to create motion and other tasks. It is a language that can be quite complex at times and can vary from machine to machine. The basics, however, are much simpler than it first appears and for the most part follows an industry adopted standard.
Know all about the concept of G codes & M codes for effective programming. • Preparatory functions (G) Overview of G codes • Miscellaneous functions (M) Overview of M codes
“M” is the address used to instruct the CNC control to perform miscellaneous functions of the machine tool such like the ON and OFF of spindle (CW/CCW), turning on/off the coolant. The word “M” accompanied by a numerical value is called the miscellaneous function or M code.
R0135. This manual covers the G and M-codes used in Mach4 Lathe. Formatting Overview: Menus, options, icons, fields, and text boxes on the screen will be bold (e.g. the Help icon). Clickable buttons will be bold and within brackets (e.g. the [OK] button).
This document lists and describes common G and M codes used in CNC machine controls. It provides over 50 G codes for positioning, linear and circular interpolation, coordinate systems, feed rates, and cycles.
24 gru 2022 · In CNC machining, M codes are used to control machine and miscellaneous functions. This includes turning off and on features such as the machine spindle as well as coolant functions. They also control how the CNC reads and flows through the program.
