- Abstract
An investigation was undertaken to seek the grinding characteristics in the grinding of boron-diffusion-hardened TC21-DT titanium alloy using a vitrified CBN wheel. The grinding forces and temperature were measured and the morphological properties of ground surfaces were examined. The results indicated that, for conventional speed grinding, material removal was mainly dominated by ploughing coupled with somewhat shearing. For the high-speed grinding process, due to the different mechanical properties between titanium substrate and hard phase particles, the strain gradient effect in the primary deformation zone (PDZ) appeared to arise. Moreover, when the grinding speed was increased to 120 m/s, chip formation by the shearing process was accounted for a positive role, resulting in a considerable improvement in the ground surface roughness. In addition, the modeling of the specific grinding energy in the PDZ, during the grinding process, was provided, and the general trend predicted by the model was found to be the same as that investigated by experimental results.
