Inverse-resolving and post-processing research of universal spindle-tilting type five-axis machine tools

In this paper a very accurate and efficient algorithm to compute the inverse kinematics of universal spindle-tilting type five-axis machine tools are presented. The spindle-tilting type five-axis machine is similar to a general serial 5R manipulator. The main idea is computing the complex inverse kinematics of universal spindle-tilting type five-axis machine to realize post processing. The proposed method in this paper has the very good generalization that can be applied to a variety forms of non-orthogonal five-axis machine and orthogonal five-axis machine.
