I am a newbe with a tabletop CNC router table which uses a Rotozip.
When cutting MDF with a new 1/4 inch two flute carbide end mill, the edges of the material are left rough and frayed. Depth: 0.10, Feed: 60 ipm, RPM: 15m.
I am producing molds for casting urethane rubber which will be used to cast plastics.
Any suggestions on other inexpensive milling substrates would be appreciated.
Thanks, Jim
