摘要： The complexity of tool path in the machining of complex curved surface is often accompanied by the large change of tool axis vector and the large change of tool axis vector can cause larger machining error and is easily beyond the restrictions of angular velocity and angular acceleration for the rotation angle of swing head or turntable of machine tool under a constant feed speed. The optimisation of the planning for the tool axis vector is very important based on the kinematics characteristics. The control method of tool axis vector based on the kinematics characteristics for five-axis NC machining of complex curved surface is studied. Experimental results show that the planning of tool axis vector based on the kinematics characteristics for five-axis NC machining can guarantee the smooth movement of the rotation axis and the machining process for complex curved surface can be more stable and reliable. ? 2015 Inderscience Enterprises Ltd.
