3.7 Drilling
Programming holes and
threads
In ShopMill, first program the technology blocks in the exact order in
which they need to be performed, e.g.
1. Centering, with tool and input of spindle speed and machining
feedrate
2. Deep-hole drilling, with tool and input of spindle speed and
machining feedrate
3. Tapping with tool and input of spindle speed and machining
feedrate
Once you have programmed the technologies, you need to enter the
position data. ShopMill provides various positioning patterns (see
Sec. "Positions").
This sequence, first technology block and then positioning block must
be adhered to in drilling cycles.
