Article Preview

On the basis of static analysis, the stiffness model of the parallel grinding machine tool is established from the 3-TPS parallel grinding machine tool newly designed by Northeastern University. By analyzing its stiffness matrix, the optimal objective is given which is the average of the twenty condition numbers of stiffness matrix corresponding to the twenty positions in the margin areas of the workspace. With MATLAB software, the effects are simulated which the structural parameters of the parallel grinding machine tool have on their stiffness, their change laws are gained, and then the stiffness design of the parallel grinding machine tool are conducted based on these laws.
