Machining trajectory planning method of workpiece

Abstract

The invention relates to a machining track planning method of a workpiece. The method comprises the following steps: determining the first preset number of reference points needing to be machined of the workpiece according to shape features of the machining track of the workpiece; enabling a movement control system to move in relative to the workpiece according to an indicator, and acquiring space coordinate information of the reference points when the indicator is aligned with the reference points; performing data processing on the space coordinate information of the first preset number of reference points by utilizing reverse engineering software, thereby screening to obtain the second preset number of reference points capable of reconstructing the machining track, and compiling the space coordinate information of the second preset number of reference points as the corresponding track code, wherein the second preset number is less than and equal to the first preset number; modelling the track code of the second preset number of the reference point by utilizing CAD software, thereby constructing to obtain a CAD model of the machining track; and processing the CAD model of the machining track by utilizing the code processing software so as to obtain a numerical control code of the machining track.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a method for planning a machining trajectory of a workpiece. Background technique [0002] The original teaching and recording process of CNC machining equipment is completed by the operator's vision and manual jogging. The whole process is not only time-consuming and labor-intensive, but also because the distance between the probe and the workpiece is determined by the operator's naked eyes. The results obtained by the operator for the distance data between the same probe and the workpiece may be very different, so that the machining accuracy of the workpiece cannot be effectively guaranteed. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a workpiece machining trajectory planning method that can reduce the technical requirements of the numerical control machining equipment for the operator and improve the machining efficiency. [0004] A method ...
