Good evening,The engraving bit I have been using is a 15 deg, 0.125" dia. v-bit. Does this help?
For this application we recommend a chip load of .004 - .006 for this material...Hi again Fred,
While I've got your attention, could you recommend feeds and speeds for cutting acrylic and also polycarbonate using an 1/8" endmill? Again, the minimum speed I can get from my spindle is about 15000rpm.
Hello Mark,Thanks again, Fred.
I have some of your single flute endmills that are supposed to be very good for cutting plastics. I'll try one of those using you guidelines and see if I can get some good cuts in poly and acrylic. I have a complicated pattern that requires some great accuracy. If I can cut it well it will yield the parts to make flexible cable chain. But the round parts must be round and smooth so that the links will rotate against each other and the whole chain will be flexible. I hope I can make it work.
