Abstract:0.008mm。By introducing the concept of surface generation points, an instantaneous force based tool deformation calculation method and the solid modeling method of deformed tool swept volume were proposed, and the solid model of machining 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 0.012mm and 0.004mm respectively, and the average error was 0.008mm. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
