Surface Generation Process with Consideration of the Balancing State in Diamond Machining

In order to manufacture optical components or mechanical parts with high requirements regarding surface quality, diamond machining is frequently applied. Nevertheless, to achieve the desired surface quality, the understanding of the surface generation process and its influencing parameters is highly important. One crucial parameter is the residual unbalance of the main spindle. As the residual unbalance affects the process and vice versa, the investigation of the process-machine interaction is necessary. In this paper results of experimental work and mathematical modelling of diamond machining under varying balancing states are presented. The experiments show the connection between unbalances and resulting surface quality; the mathematical model provides the possibility to simulate the surface quality for given unbalances distributions. Furthermore, regularization techniques in order to solve the inverse problem of computing the optimal balancing state for a given or desired surface quality are presented.
