AI Technical Summary

⚠Technical Problem

In existing technologies, optimizing compensation curves using human experience is difficult to guarantee the stability of the compensation effect. It can only be applied to specific environments, equipment, and workpiece target contours, and cannot achieve large-scale use of error compensation. The optimization cycle is long and the efficiency is low. On the other hand, grinding model simulation has a large amount of computation and takes a long time, which cannot meet the requirements of real-time generation of compensation point sets in practical applications, thus limiting the further improvement of grinding accuracy and making it impractical.

⚗Method used

By constructing an analytical model of grinding wheel profile error and using a genetic algorithm to optimize the grinding wheel profile, the target optimal profile point set is obtained. The grinding wheel profile is then adjusted to reduce grinding error and improve grinding accuracy and real-time performance.

🎯Benefits of technology

It achieves precise optimization of grinding wheel profile error, improves the accuracy and real-time performance of external cylindrical grinding, solves the problems of long grinding wheel profile error optimization cycle and low efficiency in the existing technology, and meets the requirements of high precision and real-time operation.

Abstract

This application relates to the field of intelligent manufacturing technology, and in particular to a method and apparatus for optimizing the profile of a grinding wheel in cylindrical grinding. The method includes: obtaining a set of working parameters for a target grinding wheel; constructing an analytical model of the target grinding wheel's profile error based on the working parameter set; optimizing the current profile point set of the target grinding wheel using a pre-built genetic algorithm based on the profile error analytical model to obtain the target optimal profile point set; and adjusting the profile of the target grinding wheel based on the target optimal profile point set. The embodiments of this application can reduce grinding errors caused by the grinding wheel profile by constructing an analytical model of the profile error of the grinding wheel to be optimized, optimizing the grinding wheel profile based on a genetic algorithm, and then adjusting the profile, thereby improving the accuracy of cylindrical grinding and achieving high precision and real-time performance requirements.
