2. Quick Tool (RT, Rapid Tooling) Molds are an important aspect of rapid tool manufacturing technology applications, and rapid prototyping and automated manufacturing ensure rapid tooling. The RP prototype is accurately copied into a mold by means of silicone rubber, metal powder, epoxy resin powder and low melting point alloy. The life of these simple molds is 50 to 1000 pieces, which is suitable for the trial production stage. For the manufacture of long-life steel molds, it is a three-dimensional lap from the original shape, grinding the whole graphite electrode with a lap, and then processing the steel mold on the EDM machine with electrodes. This process is characterized by fast and efficient, time-consuming 1/5 of traditional manufacturing, and improved accuracy. Using RP/RT technology to manufacture molds compared to traditional CNC machining methods, the cycle is shortened by 1/3 to 1/10, and the cost is reduced by 1/3 to 1/5. The solid model generated by RP is used as the core or mold sleeve, and combined with the techniques of precision casting, powder sintering or electrode grinding, it can quickly manufacture the functional molds or tooling equipment required for the production of the enterprise. The manufacturing cycle can be compared with the traditional CNC cutting method. Shorten by 30% to 40%, but the cost is reduced by 35% to 70%. The higher the geometric complexity of the mold, the more significant this benefit. 3. Fast direct manufacturing Rapid prototyping technology can also be used to make plastic, ceramic, metal and various composite parts using material accumulation. V. Relationship between RP&M and related technologies RP&M integrates cutting-edge technologies in various disciplines such as mechanical engineering, computer control, CAD, numerical control technology, inspection technology, and laser materials. It is a typical high-tech. 1. Relationship between RP&M and CAD technology The generation and development of CAD technology not only provides a simple and easy means for people to quickly display and modify the design, but more importantly, this method can enable people to obtain complete data, easy to modify and further processing, such as processing Data or data format files required to form RP&M, etc. Obviously, CAD is the premise and foundation for implementing RP&M, and it is often the bottleneck of RP&M in application. At the same time, the development of RP&M technology has promoted the development of CAD technology, such as data exchange interfaces and layered software. 2. Relationship between RP&M technology and materials science Materials are the key to achieving RP&M. Each RP&M process has unique requirements for its materials. For example, SLA processes use specialty photocurable resins, LOM processes use adhesive-coated paper, and FDM processes use wax, ABS, and nylon. Etc., SLS uses a variety of metal and non-metal powder materials. The nature of the material not only affects the quality of the prototype, but also has a decisive influence on the application of the prototype. More importantly, it is a guarantee of the feasibility of the forming process. The development of materials science, especially the emergence of new materials, will have a major impact on the development of RP&M technology. At the same time, the development of RP&M technology will put forward new requirements for materials science and promote the development of material design technology. 3. Relationship between RP&M and CNC technology At present, these four mature processes, SLA, LOM, SLS, FDM, etc. must use numerical control technology to achieve their forming motion control. In addition, the application of numerical control technology in RP&M technology also includes the control of processing parameters. Such as the compensation system in the SLA process, temperature compensation, power control and material feed control in LOM and FDM processes. Compared with the cutting CNC technology, RP&M requires fast scanning speed, high parking accuracy and low load. CNC technology is the basis of RP&M technology, and RP&M technology also proposes new research topics for CNC technology.
