Abstract
This paper analytically develops a type of model for predicting material removal depth in large mould polishing with coated abrasives. This model based on the statistical theory, and the abrasive material surface contact mechanics is established. The material removal depth is calculated by integrating the linear removal intensity or the removal depth per unit time along the polishing path. The material removal depth profiles of the circular abrasive tool and the annular abrasive tool are presented when polishing paths are a straight line and a curve, respectively. The effects of process parameters on the material removal depth are simulated and analyzed, such as polishing pressure, feed rate, tool speed, and internal radius, when the polishing path is a straight line. The workpiece surfaces after milling were polished by using annular abrasive tool moving along a straight line in the experiment. This model is evaluated by comparing the theoretical material removal depth with those experimental results available. It is concluded that the experiment results are approximately consistent with the model predictions.
