Abstract

The article presents the possibilities of using the MountainsMap Premium 7.4 program in the context of quantitative analysis of cBN abrasive on the single-layer grinding wheel active surface at various stages of grinding wheel wear. Two methods of grain separation available in the above software, ie. island analysis and motif analysis, were compared.

Highlights

In multi-task and multi-axis grinding centers – especially in the production of components for the aviation and automotive industries – super-hard grinding wheels with galvanic binder [1,2,3] are increasingly used, allowing for the use of higher grinding speeds, and reducing the cutting forces, extending the life of the grinding wheel and improving the quality of the ground surface [4,5,6]
grinding wheel active surface (GWAS) topography influences the interaction between the grinding wheel and the workpiece during grinding processes
It requires the selection of an optimal measuring instrument, allowing for mapping of the grinding wheel microgeometry, and the appropriate processing of measurement data and calculation of quantitative parameters. It is best if the determined parameters could be interpreted and associated with various elements of the grinding wheel. An example of such parameters are the parameters of abrasive grains located on GWAS, e.g. grain height or volume

Summary

Introduction

In multi-task and multi-axis grinding centers – especially in the production of components for the aviation and automotive industries – super-hard grinding wheels (cubic boron nitride cBN or polycrystalline diamond PCD) with galvanic binder [1,2,3] are increasingly used, allowing for the use of higher grinding speeds, and reducing the cutting forces, extending the life of the grinding wheel and improving the quality of the ground surface [4,5,6] Such grinding wheels are usually produced as single-layer ones. The problem is the description of the topography of the grinding wheel active surface (GWAS), which would allow for quantitative assessment of changes in GWAS topography due to the wear [7,8,9]
