I am trying to machine window aluminum profiles using Fomindustrie-Dali 70 machine, with pneumatic clamps and 5 mm & 10 mm end mill tool, 12,000 RPM & 0.4 feed rate. my profile is about 350 mm. during my machining process, my profile shifts. I don't know the problem is with clamping, with the oil or RPM & feed. by the way, clamping system is automatic in this machine.
I appreciate if you could help me.
Thank you
