Abstract

The paper presents the experimental study conditions and results of M3X60K5VE01-35 monocorundum with vitrified bond grinding wheel wear in 100Cr6 steel peripheral grinding process. The effect of grinding wheel wear on the values of grinding force components as well as surface roughness parameters was analyzed. The grinding wheel wear was determined by profile measurement of the active grinding wheel surface using an inductive sensor. It was shown that the increase in the normal component of the grinding force during the process can be an acceptable criterion for wear of the grinding wheel due to the quasi-linear changes over time.

Highlights

In the grinding process an important role is played by the phenomenon of grinding wheel wear, which affects process efficiency, grinding force component values and surface quality after machining [1, 2]
The main objective of the research was to determine the impact of grinding wheel wear from monocrystalline
There was a significant increase in the intensity of wear, which was probably related to the self-sharpening process by the chipping of abrasive grains

Summary

Introduction

In the grinding process an important role is played by the phenomenon of grinding wheel wear, which affects process efficiency, grinding force component values and surface quality after machining [1, 2]. That the grinding wheel does not lose, during the entire lifetime, macro-geometry obtained during the dressing process This ensures obtaining the intended shape of the workpiece and translates into less frequent restoration of the original profile of the grinding wheel active surface (GWAS). Vitrified binders are one of the most commonly used bonding materials for the production of grinding wheels This state of affairs is due to properties such as high temperature resistance, inelasticity and resistance to the influence of coolant. Due to their high strength, they allow for the creation of grinding wheels with different porosity, and enable the widest scale of hardness [1, 3]. This analysis was based on measurements of the grinding wheel active surface profiles, grinding force components and surface roughness
