Performance of Cut-Off Wheels during Elastic Abrasive Cutting of Rotating Workpieces

Abstract

This paper presents a scheme for elastic abrasive cutting of rotating workpieces which ensures constant area of the instantaneous cross-section of the layer being cut-off by maintaining constant pressing force of the cut-off wheel to the rotating workpiece. Theoretical and experimental studies of the complex impact of compression force, cut-off wheel diameter and workpiece rotational frequency on tool wear and time per cut have been carried out. The optimum conditions for the process realization have been determined by compromise optimization. Mathematical models have been created for determining the number of cut-off cycles and the average duration of a cut-off cycle as parameters for evaluating the economic efficiency of the elastic abrasive cutting process.
