Smith MegaDiamond Inc. and Star Cutter Company compared the performance of various end mills in carbon fiber reinforced plastic (CFRP). The tools tested included a coated carbide end mill, a diamond-coated end mill, a conventional PCD end mill with straight flutes, and a “veined” PCD end mill featuring a vein of PCD within a helical slot in a carbide tool body.

The table below summarizes the test parameters. Shown here is the video of a straight-flute segmented PCD tool. Jeff Michael, engineering manager for Star Cutter, comments, “Notice the sound includes pounding. This is the effect of the cutter loading and unloading because of the straight flutes. Also, there are uncut fibers because of the lack of shearing geometry.”
