CNC Program Code Explanation

N30 C-Axis Engage.
N65 M155 C-Axis Disengage.
These codes engage and turn on and off the C-axis motor.
The C-axis provides high-precision bi-directional spindle motion that is fully interpolated with X and/or Z motion.
N35 C0.0
N50 C120
N55 C240

C-Axis commands turns main spindle 0,120,240 degrees.
