The theory of similarity in turning operations

Purpose: The article presents the development of series of types of technology issues. This is an accomplished using of the innovative technological similarity theory. The transformation presented in the theory relates to the turning machining processes. Design/methodology/approach: The data generation process is concerned with the creation of the conditions and number similarities. The turning condition of similarity results from the cutting power, cutting forces and cutting performance. Findings: The development of the theory of similarity allows the generation of machining parameters for the series of types of construction (blank, machining parameters, tools). Research limitations/implications: The analyzed methods develop the algorithmisation of engineers and technologists environment and support the integration with the process of preparation of the production. Practical implications: The described methods were being developed on the practical examples of the creating of the series of types of the hydraulic cylinders used in mining. Originality/value: The method of the technological similarity presented in the paper is the basis of the selection of technological features in the process of series of types and module systems of constructions and technology creating.
