面向金属模具快速制造的机器人成型加工系统

建立了一个七轴工业机器人成形加工系统，并在此基础上开发了工业机器人熔射快速制造金属模具的新工艺．该工艺可直接由机器人铣削制造高精度、耐高温、可分离的陶瓷原型．在该原型表面熔射高熔点耐磨合金后，通过对熔射层背衬补强、并将原型与熔射层分离以及后处理，即可制得高精度耐久金属模具．与现有的熔射快速制模工艺相比，该工艺不仅缩短了工艺流程和加工时间，还提高了制模精度．

A Robotic Machining & Forming System for Rapid Spray Metal Tooling

This paper presents a 7-axis industrial robot machining and forming system, based on which a new technique named robotic rapid metal tooling is developed. With this technique, the high precision and separable ceramic prototype can be directly fabricated by robotic milling, and the prototype can resist high temperature. After the wear resistant alloy with high melting point is sprayed on the prototype, the spray formed layer is backupped, the prototype is separated from the spray layer, the post processing is completed, and a high precision perdurable metal tool is finally produced. Comparing with the existing rapid spray tooling technology, the proposed technique not only shortens the technical flow and reduces the process time, but also improves the mould dimension precision.
