The manufacturing of increasingly complex components and, at the same time, production of parts of superior quality is a growing trend in industry today. This tendency is realized through advanced machining processes that take advantage of the capabilities of the new machine tools, the properties of cutting tools and the advancements in control and CAD/CAM/CAE systems available today. However, productivity is important and it is not always possible to reduce machining times, while difficult-to-cut materials, successive processes and tool replacements hinder the desired goal. However, ready-machining of the components is a feasible way to achieve the aforementioned requirements. A possibility for this is machining the workpieces on one machine tool, with only one clamping. The fulfilment of the processing and finishing of parts with one clamping and the application of several processes, i.e. hard turning and grinding, in one machine tool is called joint or combined machining. There are several advantages to this arrangement in manufacturing processes, which are discussed in this paper.References
