Using catia, I need to make some 17mm holes. I am interpolating out from an existing 11mm hole.
Always getting entry and exit delamination.
Tool I have is a 14mm slot drill, 3 fluted, carbide.
Tried the following;
Climb & Conventional
3 Degree ramp
Flood coolant, minimal coolant, dry
Changed feeds and speeds:
1600S 120F
1600S 240F
6000S 900F
6000S 600F
Tried slotting a 14mm hole straight through first to reduce material
Tried slotting a 14mm hole then using side of cutter instead of ramping
Any ideas?
