All G And M Codes for CNC Lathe Machine Programming – The Today Blog

5/5 - (1 vote)

Want to Know the all G & M Codes of the CNC Lathe Turning Machine? In this article, I will tell you the All G-Code and M-Code Command for Lathe Machine. if you have worked on a CNC machine or are Working on it you definitely know how important these codes are.

What is G-Code?

G-Code stands for “Geometric Code”. It is a programming language for CNC (Computer Numerical Control) machines. which tells the machine how to perform a task, where to move, how fast to move, and which path to follow.

The cutting tool is driven by these G-code and M-code Commands in a CNC lathe machine.

What is M-Code?

The M-code is a set of auxiliary commands which is used to control all the machine’s non-geometric actions. People refer to it as a miscellaneous codes command as it is used to control the non-cutting actions such as stoping the machine, folding the machine with coolant, and shutting it after the temperature drop.

Difference Between G-Code and M-Code?

there are lots of differences between G-Code and M-Code in CNC Machine Programming.

G-CodeM-Code
G Code differs from lots of MachinesM Code is the same in All the CNC Machines.
G codes direct the machine’s motion and functionM codes direct the operations outside movements.
G code activates the CNC machine whileM code activates the machine’s programmable logic controller.

Important G Code Lists CNC Programming:

There are lots of Important G codes. This section will illustrate different examples of basic G and their meaning.

Important M Code Lists CNC Programming:

In addition to the G-code, there are also M-code commands which are used when generating a real full-fledged G-code program. Here are few common M-code commands:

M Code Commands
M00Program Stop
M01Optional Stop
M02End of Program
M03Spindle Rotation Clockwise
M04Spindle Rotation Anti-Clockwise
M05Spindle Stop
M07Coolant ON
M09Coolant OFF
M10Chuck Clamp
M11Chuck Unclamp
M16Chuck Clamp-on ID
M18Chuck Clamp-on OD
M19Spindle Operational Lock
M20Spindle Operational Cancel
M30End of Program then repeat the program
M46Door Open
M47Door Closed

These are some of the important M-Codes which are used in CNC Programming.
