Abstract
In this paper, adaptive diamond turning (ADT) is proposed for micro-structured surfaces to obtain homogeneous surface quality without loss of efficiency. With consideration of the local shape variation of desired surfaces, the adaptation in feeding direction is to actively control motions along the x-axis to obtain constant scallop heights, whereas the adaptation in forwarding direction is to vary angular sampling intervals to obtain constant linearization errors. The basic principle of ADT is demonstrated, and unique features of the corresponding motions of the machine tool are detailed by numerical simulation. Two degree-of-freedoms fast tool servo or slow slide servo-based turning is strongly recommended to meet the requirements of the ADT method.
