Abstract
This paper deals with a precision grinding of none-axis-symmetric aspherical surface by use of a resinoid bonded diamond wheel. Ultra-precision grinding system of none-axis-symmetric aspherical surface was developed. In this system, a resinoid bonded diamond wheel was 3-dimentionally controlled with 1nm resolution by linear scale feedback system and scanned on the workpiece surface. At first, the effects of the wheel errors on the workpiece form accuracies and surface roughness were simulated and its compensation methods were discussed. Secondly, the effect of wheel scanning direction on the workpiece surface roughness was researched experimentally. Finally, the none-axis-symmetric aspherical molding dies of a fine grain tungsten carbide were tested with a resinoid bonded diamond wheel to evaluate grinding performance.
