Hi,
We are attempting to flycut an acrylic billet on a 3axis CNC high speed router (max rpm = 18000, max feed = 800ipm). So far we have used PCD inserts at different feed rates. The issue is the tool marks and also ridges at tool stepover. The feed rates were dropped to 50ipm and the tool marks were reduced, however not the ridges. Optical quality is very important for our application. I would appreciate it if someone can answer the following:
1. Is there a specific tool/insert that works best in this operation?
2. How can the toolmarks and ridges be minimized with a greater feed rate since time is a major factor?
Please let me know if you need further information. Any suggestions/advice will be highly appreciated.
Thanks.
