Drilling commands are associated with which axis?

Drilling commands are typically associated with the Z Axis because this is the axis that represents vertical movement in a CNC milling machine. When a drill bit is engaged to create a hole in a material, it moves downward along the Z Axis to penetrate the material. This movement is crucial because it defines the depth and precise location of the hole being drilled.

The other axes, such as the X Axis and Y Axis, are responsible for horizontal movements—left and right and forward and backward, respectively. These movements can complement drilling by positioning the drill bit at the correct starting location for the hole, but they do not involve the actual drilling action. The A Axis, in some CNC configurations, typically refers to rotational movement, which is not relevant for standard drilling operations that primarily depend on vertical motion.
