I'm cutting a part out of TPO using a DMS 5-Axis Router. I have a 1/4" tool that is pulled out 2-3/4" and my material thickness is .200. I already know this IS a recipe for tool breakage but it's all I have. I have up 18,000 RPM and can cut at any speed. However I donnot know what the proper feed/speed for this perticular material is. I have been cutting ABS plastic so I have a basic idea of where to cut that at but if anyone has a idea of what the proper feed and speed for ABS is please let me know.
