Paper Abstract

In this research, ultra-precision slow tool servo (STS) diamond turning technique has been adopted to generate a freeform surface. In the previous studied, we have developed a model of three-dimensional (3-D) tool shape compensation for generating 3-D tool path in STS diamond turning of asymmetrically freeform surface. However, the form error is not acceptable when the surface sagitta or tangential slope variation too large. Therefore, the surface form error compensation method has been developed in this studied. The surface form error has been compensated from 3μm to less than 1μm by the compensation method.
