I need to experiment with engraving edge-lit plexi but have little knowledge about
it. I have run a few basic tests already using a conical engraving bit with feedrates
ranging from 60 to 180 ipm. I continue to run into problems with chips welding into
the grooves. Can anyone give me some basics about how to approach this particular
substrate, or point me to any online resources? Is some form of cutting fluid helpful
for this application? I don't have a mister or automatic lubricator, can I spray or
wipe the substrate with something before I begin, or manually mist it during cutting?
Any tool, feed rate, spindle rpm or other recommendation that I can base my efforts on
would be much appreciated.
Mike
