Paper Abstract

Bound abrasive grinding of optical materials with CNC machining equipment can achieve precise control over product configuration. For some materials and grinding geometries, however, there can be cases in which machine deflection is significant and this impacts the shape of the optical parts produced. This machine stiffness issue is associated with the relationship between the material removal rate an the applied normal load, as well as the tool deterioration process. A dynamic model to aid in keeping the process fully deterministic is presented. The validity of this model is discussed according to data collected from plano grinding of BK7 and sapphire with diamond cup tool with wide range of process parameters such as abrasive's grit size, workpiece size, infeed rate, tool dimension, and the level of glazing of the tools. Modifications and application of the model to an sphere grinding geometry is also presented.
