Tool axis vector control has been the focus of five-axis machining technology and difficulties in the control of the tool axis vector, peps axis programming system with a more intelligent and convenient, flexible control module, in the process of compiling the program, the system according to the three-dimensional contours on the surface of products automatically capture the vector direction of each node, no programming skill set or drive line drive surface and produce smoother toolpaths. For some complex shape of the product, due to the local curvature of the great changes, such as changing the curvature r nearby cutting, resulting in reducing the feed, the laser energy in the effective cutting length of the accumulation and concentration of the product burns, serious impact the quality of the product, which requires the tool axis vector direction in these areas to make the appropriate adjustments to make it the ideal tool path generation.
