Having an issue with our cutters in g10. Using 2 flute carbide 1/4in at 8k rpm with a feed of 150ipm. DoC is .135in. After one set of parts cutter has already lost .0045in on diameter and by the second set of parts the corners are rounded and the tool is at ~.241in. Is there anything we can do to keep the rpm’s and feeds without sacrificing cutters every 10 minutes?
