CIC Mirrored Acrylic
My niece needs some acrylic medals carved out. Yesterday, I was practicing with a piece of 1/4" acrylic she got me from Michael's that was on sale for 50% off. There wasn't anything on it that said whether it was cast acrylic or not. While using that, there was no issue with the bit. I did smell the plastic melting smell a little, so I sped up the Feed and lowered the RPM, which it improved.
However, when I went to the CIC Workshop mirrored acrylic, and after practicing one medal with no issues, I set up the tool path for three of them at a time. It did the first one ok, but then the other two, it was a mess-which I thought was due to my leaving the protective film on it, until it finished and I removed the Raptor dust boot and saw the wad of acrylic melted to the bit. After seeing that I started babysitting with the air compressor to blow away the acrylic chips.
I was using the CIC Workshop 60V bit. After that, I tried their 30V and it wadded up almost immediately after starting, so I changed to the IDC 90V (I don't have the CIC 90V) I have and it worked a lot better. I did see the plastic almost start to stick a couple of times, but was able to blow it away, resulting in being able to do that one okay. At this point, the non-mirrored look better when I thought the mirrored would look better.
Do y'all have any suggestions on the best v bit to use so I don't have to babysit when I start to make 50 of them?
