Abstract Heat transfer model was analyzed for polishing with ice fixed abrasives in this paper.With ANSYS finite element,the value of temperature fields for polishing was simulated.The temperature contour map of temperature field and the melting thickness values of working area of ice fixed abrasive tool were obtained.Polishing experiments were conducted with the same technological parameters.Compared with polishing experiments,the simulation result of FEM model was proved to be right.According to the simulation result of FEM,we can get the main reason of melting of working area in ice fixed abrasive tool which is not grinding heat but air convection surrounding the tool at 20oC ambient.The temperature increment followed a rule of 6rSt fast then slow. Melting velocity curve of working area of ice fixed abrasive tool was steady and change little.Other technical parameters( for example ambient temperature or polishing time) can be analyzed in advance by the FEM model,and provide theoretical guidance for research of temperature field of polishing with ice fixed abrasives.
