Hey guys , just curious what other CNC users have for there speed & feed rates for cutting Acrilyic/perspex. as most calculators ive found on the net are for Hard Materials ie: metal.. Im cutting ok at 400mm per min at 21000 RPM & a depth of 1.5mm with a millend of 1.59mm. If anyone one does know a good calculator or formula That would be great..
Cheers all....:)
