This paper introduces a method for in-process tool wear estimation of an air turbine spindle, which is equipped with a rotation control system for ultra-precision milling. Previous investigations revealed that the pressure of the compressed air for supply that is used to control the rotational speed and tool wear at the time when steady wear occurs, maintains a linear relationship when ...
For the Hellyer ball mill the calculated normal velocity and the tangential velocity for a ball in free-flight striking the mill shell in the toe area from an outermost path are U n =9.01 m/s and U t =0.425 m/s, respectively. 4.3. Estimation of shear rate. It is assumed that the kinetic energy from the normal velocity causes impact breakage.
