Tool change and Spindle commands

In CNC programming, T, M, and S commands are essential components that control specific functions of the machine.

The tool call is done with the T command (e.g., T1, T2, etc.), which selects a specific tool from the tool magazine. This is comparable to a chef selecting a specific kitchen tool for a particular task.

The M6 command is used to perform the tool change after the tool has been selected with the T command. Think of it as a mechanic picking up a wrench to start working.

The M3 command is used to start the spindle in a clockwise direction and is similar to turning on a motor. The spindle speed is specified with the S command (e.g., S1500 for 1500 revolutions per minute). This determines how fast the tool rotates, similar to setting the speed of a mixer.

M functions are special control commands in CNC programming that manage various machine functions, much like the different switches and buttons in a vehicle.

M4 is the counterpart to M3 and is used to start the spindle counterclockwise. Imagine turning the key in your car in the opposite direction to make the engine run the other way.

M5 is used to stop the spindle, similar to turning off a motor or shutting down a device.

Together, these commands enable precise and flexible control of the CNC machine, from selecting and changing the tool to setting the direction and speed of rotation to turning the spindle on and off.
