Auxiliary Method for Programming of NC Machine Tool

Abstract

The invention discloses a numerical control machine tool programming auxiliary method, and relates to the technical field of numerical control machining. The numerical control machine tool programming auxiliary method comprises the steps that (S1) accurate AUTO CAD graphs are drawn through AUTO CAD software according to the structure of a product to be machined, (S2) blade graphs are simulated through the AUTO CAD software according to the various dimensions of blades used for machining, (S3) the blade graphs are put on positions of all key points on the graphs drawn in the step (S1) respectively in the AUTO CAD software, and the radiuses of arcs needs to be determined if machining faces are circular arc faces; (S4) an original point is determined, the coordinates of all the key points relative to the original point are measured; (S5) the measured coordinates of all the key points and the radiuses of tracks of the blades when the circular arc faces are machined are provided to the numerical control machine tool for programming. According to numerical control machine tool programming auxiliary method, accurate blade tower running tracks are provided to the numerical control machine tool through the AUTO CAD software, the difficulty of data programming is simplified, and the qualified rate of complex products is improved.

Description

Technical field [0001] The invention relates to the technical field of numerical control processing, in particular to a numerical control machine tool programming auxiliary method. Background technique [0002] At present, there are more and more CNC machine tools at home and abroad. When producing and processing products, manufacturers often encounter a situation, that is, when using CNC machine tools to process products with complex shapes, the program data required for related CNC program programming is difficult to calculate. Even if the required data is obtained, it is often difficult to ensure that the required product shape and size are accurately processed at one time during processing. Although some advanced CNC machine tools can complete the self-calculation of program data, the process is complicated and is greatly affected by the state of the blade, tool bar, equipment and the level of the operator. Most manufacturers and operators have difficulty in this programming ...

[0005] At the same time, if the determination of the data required for the above programming is simply calculated according to the size of the drawing and the calculation results are input into the program, it is often still difficult to obtain qualified products. This is mainly due to the impact of the size of the cutting surface of the blade, and this Generally, it will not be affected when the blade moves in one direction, but when the blade moves back and forth or in multiple directions, the contact point between the cutting surface of the blade and the workpiece will change continuously, and the size of the cutting surface of the blade will have an impact on the product size. large impact, for which a method is needed to counteract this aspect of the
