Abstract

This application relates to a method, apparatus, equipment, medium, and program product for assessing the wear condition of grinding wheels, comprising: acquiring the actual working profile of the grinding wheel to be inspected; performing spatial registration processing on the actual working profile and a reference standard profile to align the actual working profile and the reference standard profile; calculating a target similarity index between the actual working profile and the reference standard profile; and determining the wear condition of the grinding wheel to be inspected based on the target similarity index; wherein the target similarity index is a profile similarity index based on area and curve distance. This application, by designing a profile similarity index based on area and curve distance, quantitatively assesses the degree of wear, promoting the shift of grinding wheel wear assessment from qualitative experience-based judgment to quantitative data-driven assessment, providing a digital basis for online dressing and machining compensation, and improving the consistency and efficiency of precision tool manufacturing.
