A shop experiencing on-again, off-again waviness issues during cylindrical OD grinding operations asks Dr. Jeffrey Badger why the problem comes and goes in the 39th episode of Cutting Tool Engineering magazine's Grinding Doc Video Series. Badger, the host of video series, provides some insight.
About the Grinding Doc Video Series: Thanks to his work as an independent grinding consultant and the author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine, Badger routinely receives questions about grinding from shops all over the world. Through the magazine column and this video series, he provides shops with the insight and guidance they seek.
