Research On Theory And Application Of Numerical Control Equipment Control System Product Family Design Based On Mass Customization

Manufacturing is an important mainstay of Chinese economy. Numerical control equipment industry is an important portion of manufacturing. At the same time, numerical control equipment industry provides equipments for other fields. So the status of numerical control equipment industry in manufacturing is very outstanding. Control system is the dominant portion in numerical control equipment. In the face of diversification and individuation customization requirements, conventional product design and development mode can not meet the requirements, which results in the decline of design efficiency and quality. The product mode of control system should be converted into mass customization. This dissertation researches on product family design of control system in order to elevate the design efficiency and quality. The main jobs can be summarized as follows:The main content and flow of current control system design and development have been analyzed. In the face of customization requirements, the main problems which exist in the process have been concluded from five aspects. This dissertation put forward the main idea of control system product family design, and points out its differences with other product family design or conventional product design. The critical problems which should be solved have been brought forward. The correlative definitions and technology supports have been confirmed. The system framework of product family design has been established. Two phase’s development mode of product family design has been put forwarded. The process model has been established. Then, the theory system of control system product family design has been constructed.The system skeleton of product family has been established by way of abstracting commonness and individuality from development mode, running platform, work assignment of hardware and software, and work process. The main contents and principles of function modules partition in product family have been brought forwarded. The subarea management mechanism of function modules has been established. The construction of function modules attribute and layer decompose model, function modules software and hardware corresponding model, function modules connection model, and function modules intercommunion model for product family have been brought forwarded. The processes of system skeleton establishment and function modules partition in product family have been elaborated by way of examples.The main idea, core factor, process of modularization design in product family has been brought forwarded based on the function modules partition and modeling. The main principles of function decompose in design process have been confirmed. The descriptions of function design have been accomplished by the integration of multi-view. The tasks adjusted of product family for design optimization have been studied. The design elements have been organized by modularization. The connection of modules in design phase has been confirmed. The process of function modules design in product family has been elaborated by way of example.In terms of the demand of two phase’s development mode, configuration design based on product family design universal platform has been studied. The main contents of configuration design for customization product have been confirmed. Two configuration layers of customization product have been partitioned. The principles and methods of configuration have been confirmed. The corresponding between the non-functional requirements and design schemes has been established. The process of function configuration has been confirmed by combining functional requirements with non-functional requirements. The system running circumstance has been confirmed by customization reqirement based on system speciality indexes. The mapping and tracing connection among the phases have been established. The second design process for individuation modules has been confirmed.In terms of product family design universal platform example which has been constructed, this dissertation has elaborated the implementation process of two phase’s development mode by way of a customization product development case. The design of customization product need not start from scratch, the design efficiency and quality have been elevated evidently. The important value of research has been validated.
