Machining Hard Materials with Geometrically Defined Cutting Edges — Field of Applications and Limitations

Abstract

Summary The paper deals with means of reducing production time and costs by machining hard materials. The cutting processes described are turning, milling, drilling and broaching. Tool materials for these tasks require extreme hardness and high compressive strength combined with adequate high-temperature resistance and a stable chemical structure. Surface quality and accuracy-to-size are extremely high, dispensing with the need for finish grinding.
