The Coordinated Principle of 5-Axis NC Technology
五坐标数控技术的联动原理

In this paper, the law of the coordination motion on 5-axis NC technology is Studied, the coordination principle of 5-axis NC technology is proposed, i. e., a general mathematical model on the conversion from the desired paths in a CAD model to motion trajectory is analytically derived. The geometrical properties of a desired path, including position, tangent and curvature are related to the kinematics of coordinated motion induding displacement, feedrate, acceleration. As a result, the desired velocity and acceleration of each one motion coordinate in the coordinated motion can be worked out according to the geometrical shape of the part surface and the feedrate of 5-axis machine tool.
