Cutter compensation and correction method and system of machine tool

Abstract

A cutter compensation and correction method of a machine tool comprises the following steps that an abrasion wheel wear trend coefficient S is calculated; a correlation factor coefficient P of the influence of cutting force changes and abrasion wheel deflection on the machine tool control accuracy is calculated; a correlation factor M1 of the influence of the mechanical factor of the machine toolon the machining size is calculated; a first part actual compensation value M2 is calculated according to the effective machining diameter, deflection data and rigid deformation data of an existing abrasion wheel installed on the machine tool; the size of a product to be machined is measured, and the size deviation of the product is calculated; a cutter compensation value X is calculated through acompensation and correction algorithm according to the abrasion wheel wear trend coefficient S, the correlation factor coefficient P, the correlation factor M1, the first part actual compensation value M2 and the size deviation of the product; and when the product is machined by the machine tool, the cutter position is compensated and corrected according to the cutter compensation value X. By theadoption of the cutter compensation and correction method of the machine tool, the cutter position can be automatically compensated and corrected, the time adjustment time is shortened, the product yield can be improved, and the machining output of a machining facility is improved.

Description

technical field [0001] The invention relates to the field of mobile phone shell processing equipment, in particular to a tool correction method and system for a machine tool. Background technique [0002] Glass mobile phone case products are processed on processing equipment, and the end of the tool for processing glass is equipped with a grinding wheel. Due to the influence of many factors, the dimensional accuracy of the product will be affected. The main reasons for the uncontrollable or large fluctuation range of the processing size deviation: 1. The diameter difference of the grinding wheel itself; 2. The normal wear of the grinding wheel; 3. The deflection of the grinding wheel, resulting in inconsistent wear; 4. The deflection of the cutter head; 5. The deviation of the machine tool accuracy ; 6. The grinding wheel is abnormally worn out and fails within the service life; 7. The body of the grinding wheel is rigidly deformed; 8. The cutter head clips chips. In order ...

[0002] Glass mobile phone shell products are processed on processing equipment, and the end of the tool for processing glass is equipped with a grinding wheel. Due to many factors, it will affect the dimensional accuracy of the product

The main reasons for the uncontrollable or large fluctuation range of the processing size deviation: 1. The diameter difference of the grinding wheel itself; 2. The normal wear of the grinding wheel; 3. The deflection of the grinding wheel, resulting in inconsistent wear; 4. The deflection of the cutter head; 5. The deviation of the machine tool accuracy ;6. Abnormal wear and tear of the grinding wheel, failure within the service life; 7. Rigid deformation of the grinding wheel body;

In order to stabilize the production, it is necessary for the machine operator to adjust the machine tool. However, these adjustments require high-level adjustment engineers, and the adjustment takes a long time, and the yield rate of different levels of adjustment masters is different.
