Problems solved by technology

[0011] 1) There are too many discrete points and the post-processing program is too large, which is not conducive to online transmission of processing codes
[0012] 2) Because the tool stays on the surface of the part for too long, burns may appear on the surface of the part
[0013] 3) Because it is a discrete arc, the surface smoothness is not good
[0018] According to this plan, CNC machine tools that support spatial arc interpolation have been launched on the market, but so far there is no CAM software that can support this type of machine tool, making it a high-tech display and unable to form productivity

Abstract

The present invention provides a drive method to drive CNC machine tools provided with space circular interpolation commands to conduct space circular interpolation machining, which includes procedures below: S102. Serial tool position spots in tracks of CNC machine tool A1, A2......An are structured into a circle at least; S104. One circle at least is converted into processing codes in compliance with regulations on space circular interpolation; S106. The processing code is transmitted to the CNC machine tool for space circular interpolation machining. Moreover, the present invention provides a drive device to drive CNC machine tools provided with space circular interpolation commands to conduct space circular interpolation machining.

Description

technical field [0001] The present invention relates to CAM (Computer-Aided Manufacturing, computer-aided manufacturing), in particular to a method and a device for driving a numerically controlled machine tool to perform spatial arc interpolation processing. Background technique [0002] In recent years, due to the needs of competition, manufacturers are increasingly pursuing smooth and beautiful product appearance, especially products with complex spatial curved surface appearance. The smooth surface highlights the high quality and high level of the product. [0003] At present, there are three main interpolation methods for CNC machine tools: linear interpolation, circular interpolation and non-uniform rational B-spline (NURBS) interpolation. [0004] In related technologies, a circular interpolation scheme is limited to three standard planes of the machine tool, namely XOY, YOZ and ZOX planes, and the G codes corresponding to the coordinate planes are G17 (XOY), G18 (YOZ...
