ABSTRACT

In the five-axis CNC machining, various errors caused by factors such as geometrical accuracy and dynamic characteristics of the machine tool will eventually appear as the contour error of the part. Therefore, controlling and compensating for contour errors is of great significance. This paper applies the D-H method in robot kinematics to the error modeling of CNC machine tools, and this paper takes the double turntable five-axis machine tool as the research object. In this paper, by establishing a kinematics positive solution model, the law of the contour error of the tool tip and the contour error of the tool orientation are revealed, which provides a theoretical basis for the contour error compensation control. Based on this, a contour error compensation control method is designed. Simulation experiments show that the control method can effectively reduce the contour error.
