Abstract: This paper aims at structure strength analysis which makes the static and dynamic analysis for the numerical control abrasive belt grinding machine from key components to the whole machine and obtains relevant data and conclusions. On the base of the original structure, according to the design requirements, the important parts of the grinding machine are simplified and mechanical analysis. According to the calculated results and the constraints of the machine, the mathematical modeling of key components and the limit position can be obtained by using the mathematical theory of mechanical optimization. According to the results, the entity model and static analysis can be finished. Finally, the static and modal analysis of the large grinding equipment can be carried on the FEA software and draw some important conclusions.

Abstract: A six-axis CNC belt grinding machine automatic programming technology was studied in this paper, and which used D-H rule to solve out five-axis motion variables (the DOF of A, B, X, Y, Z), then discussed the problem of maximum contact degree between the grinding wheel and contact surface, and solved out the C-axis motion variable (the sixth DOF) by the direction of principal curvature in each cutter location point, after that gave a modified method of C-axis motion variable to smooth the machining. In order to ensure the machining accuracy while improving the machining efficiency, the paper summarized the self-adaptive spacing and step distance calculation method. The results which verified by a simulation analysis were validity and reliability, and provide a new thinking and beneficial reference for the research of other similar NC programming technology.
