Final cut on Comber (Coomber) cam rings. Just need to polish and engrave.

Cutting speed is slow because I am clamping lightly on the cam ring as I do not want to distort it. Using a 25 year old Bridgeport V2E3 CNC with a 1/4 inch 2 flute carbide cutter at 4000 RPM. The inside of the ring has been roughed out with 1/32 of material left for the final cut. I brushed the inside with Tapmatic Edge Liquid for a cutting fluid before mounting the part. The cam profile is generated by a parametric program so the CNC does all the cutter path calculations and the program is only about 160 bytes long.
