Hi all,
Have some acrylic letters to cut later and can’t find my reference book……

Just got in this morning, sorry for the late reply are you running carbide spiral O tools, if so i would use a 4mm tool and cut the job with two passes @ 17mm/sec 21000 rpm. Your feeds and speeds book may disagree however these speeds work well for me on acry and the carbide tool strokes leave a decent finish that helps with the polishing
Hope this helps have a super day -
thanks for the help Barrett.
Cheers
Joe
