Development of a construction technique for the complex details in the application of group process with the use of CAD "T-Flex"

Introduction. In modern conditions of enterprises engaged in production of standard parts in various parties, meet the need to reduce time for preparation and changeover production while maintaining efficiency. These problems can be solved by typing processes and operations, presented in the form of a group of technological parts processing. Design of the processing associated with the process of construction of the complex parts that must meet all requirements imposed on the group of manufactured parts. The paper deals with the problem of constructing the complex details of the design group of the process of machining. Materials and Methods. On the basis of the drawings of the "body rotation" type components proposed approach is to implement the overlay method used for the construction of complex parts using a parametric computer-aided design features "T-Flex". Results. As a result of analysis of drawings and using the overlay method was established parametric model complex parts, formed by a group of the "body rotation" parts using computer aided design "T-Flex CAD". Discussion and Conclusions. A method of forming a parametric model includes analysis of a sketch drawing of complex parts and components of the table corresponds to the group for the required number of parameters, the formation of the database parameters to build a visual geometric model. This allows the possibility to use a group technology parameterization processing components that provide simplicity and ease of adding details of the selected groups and details of type and realize the possibility of reducing the design time process, and hence the production time for preparation.
