A novel computer aided geometric approach is proposed to machine a 3D free surface by adopting a 3-RPRU parallel machine tool. Based on the geometry constraint and dimension-driving technique, a 3-RPRU parallel simulation mechanism is first created. Next, a 3D free surface and a guiding plane of tool path are constituted. Finally, the 3-RPRU parallel simulation mechanism, the 3D free surface, and...
