By introducing the concept of surface deformation calculation method and the solid proposed, and the solid model of machining generation points, an instantaneous force based tool modeling method of deformed tool swept volume were simulation including geometry and physical errors were generated. The machining process was shown by computer graphics dynamically and the measurement method for solid model of machining simulation was also presented. The whole system was implemented by using OpenGL and PARASOLID modeling kernel. The result of machining simulations case study and the actual machining experiments indicate that the maximum and minimum simulation errors were 0.012 mm and 0. 004 mm respectively, and the average error was 0. 008 mm.
