Analysis of spherical chips after grinding
Original language description
Grinding is a conventional technological operation necessary for the manufacturing of mechanical parts of precise shapes and sizes with high demands on surface roughness. The machining is done with a tool with an undefined cutting-edge geometry composed of individual hard grains which are connected by a binder. Small cross-section chips form during machining with the grains. These chips undergo great plastic deformations and suffer a heating of such magnitude due to the inner and outer friction that it causes melting and a subsequent forming of a metal ball. The goal of this study is to analyse these balls – chips after grinding, formed during the machining of D2 tool steel with an Al2O3 grinding wheel. 4 types of balls were found and examined. A focused ion beam was employed to sputter a part which allowed the study of their inner area. An analysis of the chemical content was carried out both on the outside and the inside of the ball. The carried-out analysis led to the discovery of two new types of balls that form after grinding. The analysis brought new findings about the types of chips after grinding and, as such, this study will contribute to a more thorough understanding of the grinding process.
