Method of for grinding - Massachusetts Institute of Technology

From the force data in FIGS. 8 and 10, it was clear that orientation angles of 45° and -45° produced highly erratic behavior during grinding. When α=-45°, the high stiffness direction was nearly aligned with the resultant grinding force and the behavior appeared to be a high frequency limit cycle with low frequency beats.
