For cylindrical surfaces requirements for roundness deviation, deviation the straightness of the generatrix of the cylindrical surface and straightness of the axis can be determined. In this paper the existing associated reference elements are analyz

Many authors involved in the processing of materials by cutting make different definitions for complex rotary surface. They are reduced to the definition published in [1]: A complex rotating surface is called one that is composed as a combination of

Looking retrospectively at the many years of efforts by a number of researchers to develop a method for machining by cutting of polyhedral parts, it is found that the obtained results were not particularly satisfactory. For this finding, it is not po
