在工业产品向多样化、高级化方向发展的进程中,提高模具精度已成为一个重要的课题。因为模具精度直接关系着成形加工制件的质量。模具中有塑料模、冲压模、压铸模等种类,其形状结构与精度要求各异。特别要提到的是设计者构思的模具,有许多是由难以用数学公式表达的三维曲面所构成。因此,使制作程序变得更为复杂。从图1就可以看出,模具的制作工艺流程与一般采用加工中心等机床加工的零件不同,有许多技术上的特殊性。模具制造要实现低成本、自动化、高效率,必须从模具设计、机械加工、手工精修、三维形状测量、装
In the industrial products to the diversification, the direction of the development of high-level, improve the accuracy of the mold has become an important issue. Because the accuracy of the mold is directly related to the quality of the parts processed. Plastic mold, stamping die, die-casting mold and other types, the shape and structure of the different precision requirements. Particular mention is made of molds conceived by the designer, many of which consist of three-dimensional surfaces that are difficult to express in mathematical formulas. Therefore, the production process has become more complicated. As can be seen from Figure 1, the mold manufacturing process and the general use of machining centers and other parts of the machine tool is different, there are many technical particularities. Mold manufacturing to achieve low cost, automation, high efficiency, must be from the mold design, machining, manual finishing, three-dimensional shape measurement, equipment
