Problems solved by technology

At present, due to the lack of automatic detection technology after the grinding wheel is worn, offline measurement of the workpiece is generally used, and the compensation of the grinding wheel is controlled according to the measurement results. It affects the processing accuracy and makes the processing time too long; on the other hand, because there is no detection, it is difficult to accurately grasp the time of grinding wheel compensation, and it can only be determined by experience when the grinding wheel should be compensa

Embodiment 1

[0036] An automatic detection and compensation method for grinding wheel wear, characterized in that: a grinding wheel corrector is used to automatically correct the cycle of the grinding wheel after grinding, and a grinding wheel diameter detector is used to conduct online detection of the grinding wheel diameter in processing, and the grinding wheel diameter data obtained after detection Send it to the CNC system, and the CNC system compares the grinding wheel diameter data with the original grinding wheel diameter data, and obtains the grinding wheel wear amount and the grinding wheel correction amount (the consistency of the grinding wheel wear amount and the grinding wheel correction amount is related to the micrometer and machine tool accuracy), and the CNC system Control the feed amount of the machine tool (U-axis feed) to realize the automatic compensation of the grinding wheel. Wheel dressers and wheel diameter monitors are common devices on the market.

Embodiment 2

[0039] On the basis of Example 1, the grinding wheel diameter detector is an optical micrometer. (The optical micrometer is a commercially available device) The grinding wheel diameter detector is not only used for the detection of the grinding wheel diameter, but also for the detection and compensation control of the planetary grinding radius of the CNC jig grinder. The grinding wheel diameter detector is not only used for the detection of the grinding wheel diameter, but also for the detection and compensation control of the coincidence of the cutting edge of the grinding wheel with the continuous trajectory of the CNC coordinate grinding machine and the center of rotation of the C-axis. The grinding wheel diameter detector is not only used for the detection of the grinding wheel diameter, but also for the detection and compensation control of the thermal drift of the grinding spindle of the CNC coordinate grinding machine. According to the automatic grinding wheel correctio...

Abstract

The invention discloses a method for detecting and compensating for abrasion of grinding wheel automatically and relates to the technical field of a grinding method of grinding wheels. A grinding wheel dresser is adopted to automatically dress and circulate ground grinding wheels, a grinding wheel diameter detector is adopted to perform on-line detection on diameters of machining grinding wheels, and diameter data, acquired after detection, of the grinding wheels is transmitted to a numerical control system; the numerical control system compares the diameter data of the grinding wheels with the original diameter data of the grinding wheels to acquire the abrasion loss and correction of the grinding wheels; and the numerical control system controls the amount of feed of a machine tool to realize the automatic compensation of the grinding wheels. By adopting the method, when precision moulds are ground, the precision of grinding outlines can be ensured effectively, the efficiency is high, and the automation and datamation control in the process of grinding the precise moulds are realized; and automatic and digital processing of quenched complex parts, such as plane graphic sample plates with any curves, mould cavities, mould punches and the like can be realized.

Description

technical field [0001] The invention relates to the technical field of grinding wheel grinding methods, in particular to an automatic detection and replenishment method for grinding wheel wear in grinding equipment. Background technique [0002] In CNC forming grinding machine processing, the shape of the workpiece directly depends on the shape of the grinding wheel. When the grinding wheel is worn, the wear of the grinding wheel should be detected and compensated in time, otherwise it will cause processing errors. At present, due to the lack of automatic detection technology after the grinding wheel is worn, offline measurement of the workpiece is generally used, and the compensation of the grinding wheel is controlled according to the measurement results. It affects the processing accuracy and makes the processing time too long; on the other hand, because there is no detection, it is difficult to accurately grasp the time of grinding wheel compensation, and it can only be ...
