2.3 Units—Recessing
"Parting" unit
The unit parts the workpiece. If programmed, a chamfer or rounding
arc is machined on the outside diameter. At the end of cycle, the tool
returns to the starting point. You can define a feed rate reduction,
which becomes effective as soon as the position I is reached.
