Peck milling
What is successful peck milling?
Peck milling is an alternative to ramping for opening up in solid material. However, it requires excessive power, produces long chips and places undesirable cutting forces on the cutter. Peck milling should therefore only be used when:
- The machine lacks ramping capability
- Producing short closed slots
How to apply peck milling
Centre cutting - drilling end mills (end milling cutter)
The drill depth of a centre cutting end mill is limited by the length of the chip flute and also by chip evacuation capability. For deeper slots, use a peck cycle. When drilling, use a low feed: approx. 50% of the feed recommended for milling.
Note: consider ap max for full slotting milling.
