Figure 16.5 shows the axis motions that make up the G83 incremental
plane grinding cycle. This figure assumes that the YZ plane (G19) is
active. Since the Y axis is plane axis 1 for G19, it is the plunge axis.

Programming a G83 or G83.1 causes the control to execute an incremental
plane grinding cycle using three axes. “Incremental” refers to cross pick
move executes in a single increment at the end of each reciprocation move.
A plunge move towards the part is made after each crossover is completed.
The G83.1 begins with a pre-dress operation prior to the grind.

The G83 cycle dictates that the axis configured as axis one in the active
plane makes the plunge move. The axis configured as axis two in the
active plane makes the cross pick move, while the axis not in the active
plane is the reciprocating axis.
