I have to router some parts out of MDF. This is one material that I do not have any experience with. I need to route through 1/2" sheet using a 3/8" carbide cutter. What flute number and configuration do I need? Straight, downshear, or upshear. I am hoping to be able to vacuum the part down on another sheet of MDF to hold it, but I am not too sure it will hold. Maybe I will need to make a spoilboard. The part looks like a 10" steering wheel. Any suggestions on feeds and speeds would be greatly appreciated. I have 7.3 kW spindles rated up to 24,000 rpm. I was thinking about 18,000 rpms with 400 ipm to start. What cut should I use as well? Climb or conventional.
Any input would be appreciated.
Thanks,
Paul
