作为一种较成熟的快速制模工艺,机器人熔射快速制造金属模具工艺可广泛应用于家用电器、汽车、航空航天、医学等领域.机器人直接制造陶瓷原型是其中的一个重要工艺环节.本文建立了面向机器人熔射快速制模工艺的工业机器人成型加工系统,开发了面向复杂形状陶瓷原型的机器人多轴成型加工工艺.利用UG多轴铣加工模块的基本功能,采用辅助平面法来生成机器人的多轴铣削加工轨迹,能够灵活加工通常只有多轴数控机床才能加工的复杂模具型腔.实验结果表明,该工艺不仅提高了机器人的成型加工能力,还扩大了机器人熔射快速制模工艺的应用加工范围. 相似文献

Faster,Less Expensive Dies Using RSP Tooling 总被引:2,自引:0,他引:2
James R. Knirsch 《Journal of Materials Engineering and Performance》2007,16(4):432-439
RSP Tooling is an indirect spray form additive process that can produce production tooling for virtually any forming process
and from virtually any metal. In the past 24 months a significant amount of research and development has been performed. This
resulted in an increase in the basic metallurgical understanding of what transpires during the rapid solidification of the
metal, significant improvements in the production machine up time, ceramic developments that have improved finish, process
changes that have resulted in a shorter lead time for tool delivery, and the testing of many new alloys. RSP stands for Rapid
Solidification Process and is the key to the superior metallurgical properties that result from the technology. Most metals
that are sprayed in the process leave the machine with the same physical properties as the same metal normally achieves through
heat treatment and in some cases the properties are superior. Many new applications are being pursued including INVAR tools
for aerospace composite materials, and bimetallic tools made from tool steel and beryllium copper for die casting and plastic
injection molding. Recent feasibility studies have been performed with tremendous success.
