160 smart.Turn units for the Y axis
3.1 Units—Dr
illing in the Y axis
3.1 Units—Drilling in the Y axis
"ICP drilling, Y axis" unit
The unit machines a single hole or a hole pattern in the XY or YZ plane.
Using ICP, you define the holes as well as further details.
Unit name: G74_ICP_Y / Cycle: G74 (see page 319)
