176 smart.Turn units for the Y axis
3.3 Units—Milling in Y axis
"ICP pocket milling in XY plane" unit
The unit mills the pocket defined with ICP in the XY plane. In QK
(machining operation), select whether a roughing or finishing
operation is to be executed. For roughing, define the plunging
strategy.
