Application development in centrifuge design for mass customization – centrifuge
Abstract The emergence of mass customization coupled with increasing global competition, forcing more and more manufacturers to participate in the search for a wide variety of design strategies. In fact, mass customization is becoming a cost to meet both the trend in providing more varieties of products but also an effective way. First described to solve various problems in design for mass customization approach, then this approach were applied centrifuge product family was designed to verify the design for mass customization Technology The accuracy and effectiveness.

Design is considered finished form, cost, reliability and market acceptance of the important factors. Improved product design can greatly reduce the costs very little and only need to increase the design cost. According to statistics, in the product life cycle, typically 80% of the manufacturing cost, the quality of 50%, 50% and 80% of orders in advance of the commercial complex depends on the product and process design.
Design (usually including machinery, Electric And Software And so on) by the user requirements and operational specifications determined. Therefore, how to satisfy the needs of users, designers will be the primary consideration.
With the global market on the product cost and increasing customer demand for individual competition, the manufacturing sector while meeting the need bear production efficiency and product variety these two contradictory pressures. So, how the cost of mass production to meet customer's individual requirements, that access to a wide range of mass customization attention.
Mass customization (MassCustomization, MC) concept first appeared in the late 80s of the 20th century, first by the Davis predicted: that through the process of mass customization is a highly agile, flexible and integrated to provide to each individual client design of products and services.
Successful implementation of mass customization depends on a number of factors: (1) must be present on the product variety and mass customization of customer needs; (2) the right market conditions; (3) prepared the value chain; (4 ) viable technology; (5) personalized products; (6) shared knowledge.
Enabler of mass customization is defined as the factors supporting the development based on the organization of some technologies and methods. Mainly the following three aspects: (1) support the process and methods of mass customization; (2) support mass customization technology, advanced manufacturing technology major (AMTs), such as Computer Numerical Control (CNC), flexible manufacturing systems (FMS) and communications, network technologies, including computer-aided design (CAD), computer aided manufacturing (CAM), computer integrated manufacturing (CIM) and Electronic Data Interchange (EDI), etc.; (3) how to support information technology transformation, namely, the implementation of the main problems of mass customization.
Because of the design in the product life cycle in the importance of design for mass customization has become the design of new developments. Therefore, this article will make a simple design for mass customization paper, and then describes the design for mass customization in the application of mechanical separation.
1 design for mass customization [9 ~ 13]
Design for mass customization (DesignforMassCustomi-zation, DFMC) (Tseng and Jiao, 1996) early in the product design stage to consider economies of scope and economies of scale. DFMC's main focus is to improve the current design of individual products to product family design. In product family design, the use of modular technology is undoubtedly essential.
1? 1 modular product family design of multi-view
Product family architecture can be defined as the mapping between different scope, as shown in Figure 1. In the customer domain, the main task is to find out exactly what the customer needs. In the functional domain, a series of functional requirements to be characterized in order to meet the specific needs of specific customers. In the physical domain, the design parameters that must be considered is the feasibility? Similarly, in the process domain, the process needs to be adjusted, called the process variable, it represents a design change on the impact of manufacturing and customization required to achieve that cost.
Modular technology is a systematic way, not only used in the product design stage and throughout the product manufacturing, organization, and many other stages, namely the implementation of modular technology must be run through the entire product life cycle to sufficient to ensure mass production of the final product to meet specific customer's individual requirements. Obviously, in which, concurrent engineering (ConcurrentEngineering, CE) of the ideas and strategies that should be seriously study and learn, more importantly, the modular technology to practical applications.
(1) system level System layer is a complete assembly system, which is composed by different modules. The modular system level is usually the extent of its interface with the increase significantly reduced.
(2) module layer Module components layer by layer in the different components to create, craft, such as electrical, mechanical or chemical.
(3) component layer Modular component layer is considered the lowest level, usually composed of a number of standardized parts. In the component level, standardization is a prerequisite for the implementation of modular, standardized components to provide a convenient reusable components.
Standardized components is usually some public component, has a well defined technical specifications and are widely accepted by industry. At the same time, and other components of its interface compatibility issues have been well resolved and norms.
Companies have chosen the benefits of the existing mature component are: (1) reduction of investment: the reuse of existing components to avoid the development of downstream products, and tools such as additional investment; (2) from the perspective of product volume increase scale effect; (3) maintained a business on the professional capacity building.
2 instances [14 17] Although the separation range from mechanical, chemical, and thermal isolation and separation of power, but the centrifuge technology and other separation technology, has the following characteristics: (1) small size; (2) short residence time; (3) without filter aid; (4) system sealed; (5) enlarge simple; (6) The process is continuous; (7) handling large; (8) the separation efficiency and so easy to adjust. Because of these characteristics, centrifugal separation technology by industry attention. At present, centrifuge machine has been widely used in resource development, environmental protection, biotechnology, defense industry and the chemical, pharmaceutical, food, textiles and shipbuilding nearly 10 industrial sectors, diversification of customer demand for personalized centrifuge machine implementation laid the foundation for mass customization. In recent years, with the new technology and new technology development, particularly biotechnology driven centrifugal separation technology further in the high parameters, automatic, multifunction, automatic control systems and the development of new materials such as showing a trend.
Overall, centrifuge machines can be divided into
