Hello!
I'm new to hobby cnc'ing. The question is about optimal feedrate, step depth and rpm for cutting out details from plywood.
Situation:
Birch plywood 18mm thick (~700kg/m3)
Kess 1050 FME 10000..32000 RPM
Cutter- cutter d=3mm, shank d=3mm, cutlength=20mm, overall length=38, no. of flutes=3, VHM, upward chip ejection (a "noname" from ebay)
Max speed for machine (that stepper motors feel comfortable ) as I have set it up in Mach3 is 50mm/sec.
The job consists of cutouts, there are only few small pockets, 5mm in depth.
What would be Your suggestions on those parameters? Primary I don't search for "fastest" approach, but the most "correct" one. The thing that worries me is the "composite" nature of plywood (this one is bonded with a phenol resin adhesive (EN 314 / 3 rd class; BS 1203 / H4 (previously WBP); DIN 68705 Part 3 / type BFU 100)).
Thank You so much in advance!
