Effect of Modification of Mono-crystalline Corundum Grinding Wheel on Cutting Forces in Grinding of Aluminum Alloy 7075

Abstract

The paper presents an analysis of the process of grinding of aluminum alloy 7075. A monocrystalline corundum grinding wheel with a modified spatial structure was used for the tests in the direction of even “opening” of the grinding wheel during the grinding process. The components of the grinding force measured using the 3-component Kistler 9121 dynamometer and force models for variable grinding parameters were developed using the RSM methodology. The performed tests show the possibility of elaborating models of the components of the cutting force in surface grinding. The empirical models of the cutting force components for a modified grinding wheel were developed. The test results were compared with a conventional wheel with the same hardness, grain size, and structure.
