Double sided grinding of advanced ceramics with diamond wheels

A double side grinding (DSG) computerized kinematical model accounting for piece rotation inside its slot into the carrier was developed. Trajectories for representative points located on the end faces of the workpiece were simulated. A radial wear gradient of the active surface of the wheel was predicted. Experiments accomplished with different wheel specifications, process parameters, operation duration, and coolant types were carried out. A strong correlation was found between the predicted length of the trajectory of a specific point located on the piece surface and the experimental material removal rate. A radial wear gradient was experimentally confirmed. Conclusions on optimizing the DSG process for advanced ceramics with diamond were drawn. 2006 by Taylor & Francis Group, LLC.
