Abstract

Surface roughness is an important factor in characterizing the performance of high-precision optical surfaces. In this paper, we propose a model to estimate the surface roughness generated by a single-point diamond turning machine. In this model, we take into consideration the basic tool-cutting parameters as well as the relative vibration between the tool and the workpiece in both the infeed and feeding directions. Current models focus on the relative tool-workpiece vibration in the infeed direction. However, based on our experimental measurements, the contribution of relative tool-workpiece vibration in the feeding direction is significant and cannot be ignored in the model. The proposed model is able to describe the surface topography for flat as well as cylindrical surfaces of the workpiece. It has the potential to describe more complex spherical surfaces or freeform surfaces. Our experimental study with metal materials shows good correlation between the model and the diamond-turned surfaces.
