This article argues that cutting tool wear is not just a particular case of wear found in general machinery because the whole amount of energy required for cutting is transmitted through relatively small tool-chip and tool-workpiece interfaces causin

The chapter gives a historical prospective of the origin and developments of empirical equations for cutting force in the manner never presented before. It is shown that the Wiebe formula published in 1858 is still in wide use today in many research

International audience; The accuracy of a machining model depends on the capability of this model to describe the physical phenomena associated to the real machining system. This includes the material constitutive model and the approach used to descr

An analysis of publications has shown that mechanically clamped indexable inserts are predominantly used in modern tool manufacturing. Each insert has its shape and geometry in the tool coordinate system. The static system’s required geometry is ac

Most of the energy spent on metal cutting is due to the unavoidable plastic deformation of the layer being removed during its transformation into the chip. Based on the new principle of metal cutting being a purposeful fracture process, the dominant

This chapter reveals the modern objective of metal cutting processes as increased productivity of multiple machining operations. It is discussed that the only feasible option to increase productivity is increasing the cutting speed. The chapter furth

The material fracture behavior and associated mechanism is known to be affected by the stress state and strain rate. Using a recently developed rectangular hat-shaped specimen, the fracture behavior of Ti6Al4V was investigated with a stress triaxiali
