A shop that grinds tungsten-carbide endmills using a resin-bonded diamond wheel turned to Dr. Jeffrey Badger for the 37th episode of Cutting Tool Engineering magazine's Grinding Doc Video Series because one of the shop's wheel suppliers was talking about Q prime values. According to the supplier, the shop should be using a Q prime value of 6 or 7. So the shop asked the Grinding Doc, "What's up with Q prime values?"

A wheel supplier urged a shop to use a 150 mesh grit wheel to put a 0.005" radius into a part, but when the shop went from its 80 mesh grit to the smaller grit the result was horrific chatter. In fact, the shop always gets chatter from small grit wheels. For some explanation, the shop wrote to Dr. Jeffrey Badger, the host of Cutting Tool Engineering's Grinding Doc Video Series, for the 36th episode of the video series.
