Hi,

I'm having real problems machining acrylic sheet, i've been routing 3 & 4mm thick A4 acrylic sheet, and am really struggling to hold it down securely, whatever I do the sheet gets pulled up by the bit ( i've been using 3 and 4mm end mills), i've even tried using a vacuum table unsuccesfully. I'm doing shallow cuts less than 1.5 mm and slow feed rates.

Any suggestions would be appreciated as at the moment i'm wasting a lot of acrylic.

Cheers

Alan
