OT - Machning Acetal homopolymer (Delrin)

Hi to all,

I need a litle advice about cutting that material. Here what I have:
- 3mm dia 2 flute end mill fish tail;
- spindle RPM max 20.000 0.5 HP;
- router - max rapid speed 6000 mm/min
- material tickness - 25 mm
- file which will be cut has some pocketing and 3D profiling.

I also have a copy of tool box machinist software. Putting all data (about cutter and material) inside that speed and feed calclator give me the following result's (all metric):
- surface speed - MPM = 114 (that value it is already presetted when you choose the material);
- load per flute = 0.1524;
- RPM = 12095;
- IPM = 145.14;
- mmPM = 3686.556;
- Max Radial DOC = 1.2;
- Max Axial DOC = 2.55;
- required power = 0.24.

I am little scared about that figures and I would like somebody more experinced to have a look on that and give me his/her opinion's.

Thank you for your time
Gabi
