Example: Slot milling
A horizontal slot 50 mm x 10 mm and a vertical
slot 80 mm x 10 mm are to be milled.
The starting position takes into account the tool
radius in the longitudinal direction of the slot.
Starting position slot 1 :
X = 76 mm Y = 15 mm
Starting position 2 :
X = 20 mm Y = 14 mm
SLOT DEPTHS: 15 mm
Setup clearances: 2 mm
Milling depths: 15 mm
Pecking depths: 5 mm
Feed rate for pecking: 80 mm/min
