Research Abstract

A controller for driving multi-axis machine was combined with a Jacobian matrix, V-F transformer, and forward kinematics. Different from previous ones, this NC controller for driving multi-axis machine can generate a pulse series in real time so that the machining velocity and shape can be changed in real time to meet machining requirements. A simulation of machining a circle by using the new NC controller for 5-axis control machining center demonstrated its effectiveness. For machining pieces with complicated shapes, multi-axis machines, such as 5-axis control machining centers, are widely used because orientation of the tool is usually required during machining. For example, in order to obtain a tool path accurately, tool orientation is required to keep in the direction of normal line of a cured machining trace. In addition to tool orientation, the motional trace of the tool tip and its velocity must be controlled at a desired value under machining cured surface. In the case of machining a work with complicated shape, it is difficult to generate the tool path accurately according to the interpolation of line and curve by using a conventional NC controller. To solve these questions, an NC controlling method is proposed. In this method, the corresponding pulse series for movement and motional velocity of a driving axis can be generated in real time with computer software to obtain a desired tool path. Just like control a multi-joint robot, a 5-axis machining center can be controlled by building coordinate system and calculating its Jacobian matrix.
