Problems solved by technology

Due to the large number of processed products sometimes, positioning, calculation, and manual input are required for each processed product. The risk of human error is extremely high. In actual processing, many products have been out of tolerance and scrapped due to human error. While wasting people and time, it also wastes a lot of cost

Embodiment Construction

[0031] A kind of numerical control processing method of multi-zero parts, described method comprises the following steps:

[0032] (1) According to the calculation method of the zero point of the part, write the zero point calculation program and input it into the CNC machine tool;

[0033] (2) Install the part on the fixture of the numerical control equipment, and input the design coordinate values ​​of the reference hole of the part and all zero points of the part into the numerical control equipment;

[0034] (3) Use the probe of the numerical control device to measure the mechanical coordinates of the two reference holes on the workpiece, and then input the coordinates into the data device;

[0035] (4) Call the zero point calculation program to automatically calculate the mechanical coordinates of multiple zero points and automatically write them into the specified machine tool address;

[0036] (5) Complete the processing of parts according to the calculated mechanical ...

Abstract

The invention relates to a numerical control processing method of a multiple-zero-point part. According to the actual condition in the part processing process, after the actual position of a reference hole on a machine tool is recorded, according to the theoretical position relationship of each point, the actual coordinate value of each zero point on the machine tool is calculated, and through program language programming input, the problems of complicated calculation, two much input points and high rate of human errors in the prior art are solved. According to the method, the errors caused by artificial calculation and the input of a plurality of zero points are eliminated, since the efficiency of calculating and inputting the zero points is high, thus the processing efficiency is greatly improved, and the time of production and manufacture and labor cost are saved.

Description

technical field [0001] The invention relates to a numerical control machining method, in particular to a numerical control machining method for multi-zero parts. Background technique [0002] In the NC machining process of complex parts, certain points on the part need to be used as the processing reference, that is, the zero point of the part, during the completion of all the processing procedures. Due to the error between the actual position and the theoretical position of the part during the processing, it is often necessary to calculate the actual coordinate value of the zero point. Place it on the machine tool, measure the coordinate value of the reference hole of the part on the machine tool, that is, the mechanical coordinate value, and then the technician calculates the mechanical coordinate value of other zero points according to the mechanical coordinate value and the design coordinates of other zero points, and the operator then calculates The mechanical coordina...
