CNC Feeds Principles
- Establish a firm start
- Feed steadily to allow heating
- As point penetrates through material thickness start to accelerate
- Finish with collar forming Last part feed distance ie 1 x material thickness Slow feed rate while forming collar
- Finish with flat style - flush finish Last part of feed distance ie 1 x material thickness
Rapidly accelerate feed rate
Examples for illustration purposes only. Adjustment will normally be needed for best results.
