Position Analysis of A New 3-legged Parallel Machine Tool

A new 3-legged parallel machine tool is introduced in this paper. This machine tool is created in Northeastern University recently. It can be able machining vertically as well as horizontally. Its restriction mechanisms has been analyzed. Solution of the inverse position problem has been obtained. Its inverse kinematics is simple, computation quantity is small and it is easy to accomplish its real-time control. Its workspace is large. It has a high application value in manufacturing field.
