During hard turning the original hardness of the surface layer changes, as does its texture structure and stress state. Even cracks and other defects may appear if the heat effect is too intense. As experimental investigations into heat effects are d

Hard turning process is widely used for finishing the hardened surfaces of machine parts exposed to high load. Such parts can be gears, bearings, or short shafts. As in each machining process, hard turning may change the properties of the surface lay

In high-speed cutting of hardened steels, the surface layer is strongly affected by thermal effects and mechanical forces. Due to this, the surface layer of the machined material changes noticeably. Microhardness, one parameter of the surface integri

Nowadays, hard turning is frequently used to replace grinding. The economic benefits of hard turning are obvious but for achievable accuracy the situation is somewhat ambiguous. Although machine tool factories offer lathes with the same accuracy as g

A simulation of the precision grinding of steel was performed using an implicit finite element code, namely the commercial code MARC, in order to describe the temperature fields developed during the process. The input data required a model obtained v
