Grinding Of Pcbn Cutting Inserts Sciencedirect

Jan 01, 2014 Denkena et al. measured the forces during grinding PCBN inserts with a TiN bonding, different grain sizes and PCBN fractions. The authors show that an increase of the PCBN grain size decreases the grinding forces, since a brittle material removal mechanism predominates. Otherwise a variation of PCBN fraction does not show any influence.

Prediction Of Grinding Force Distribution In Wheel And

A novel method is reported for predicting the distribution of normal and tangential grinding forces in wheel and workpiece contact zone or along their contact arc. This work was motivated by the need to obtain the maximum force acting on individual active abrasive grains for establishing the probability of grain fracture and pullouts due to this force.
