为了建立模具的自动化制造系统,模具工业中必须首先解决两个问题。一个是自动设计系统。二是模具腔面的表面精加工技术。特别是塑料模具的型腔表面仍然是由一个熟练的机械师手工完成的,在本研究项目中,获得了模具熟练的机械师的模具抛光操作的知识,开发了一个良好的自动抛光工具的性能,并建立了一个专家系统来设计抛光工艺。通过对抛光过程中表面粗糙度、切削量和划痕的测量,得到了抛光过程中机械手的抛光性能,并对其进行了定量分析.利用机械师的知识构建了模具抛光专家系统,并通过模具车间的实验验证了该专家系统的可行性.用不同的抛光工具进行了抛光实验,不仅由熟练的机械师手工完成,而且通过使用数控铣床的机械方法完成。根据该专家系统的求解结果,选择合适的抛光工具和抛光行程数对S55C钢铣削表面进行抛光.因此,该专家系统被证实是有用的调度和确定的抛光工艺,它被验证,该开发工具的性能类似于专家的模具机械师的性能。
英文摘要
In order to establish an automatic manufacturing system for dies and molds, two problems in the mold industry must primarily be developed. One is an automatic design system. and other is a surface finishing technology for acavity surface of dies and molds. Especially, the cavity surface of plastic mold is still finished by handiwork of a skill machinist.In this research project, the knowledge of a mold skilled machinist for mold polishing operation was acquired to develop good performance of an automatic polishing tool, and an expert system to design the polishing process were established.The study is summarized as follows :1. The polishing properties of a skilled machinist in respect tosurface roughness, stock removal and scratch were obtained and analyzed quantitatively.2. An expert system for mold polishing by using the knowledge of skilled machinists was constructed, and the feasibility of the expert system is verified with experiments in die and mold shop.3. Finishing experiments were carried out with different kinds of polishing tools, not only by a skilled machinist handiwork, but also by mechanical method by using NC milling machine.4. According to the solution of this expert system, milled surface of S55C steel were polished with selected tools and the number of polishing strokes.5. Consequently, this expert system was confirmed to be useful for scheduling and determination of the polishing process, and it was verified that the performance of this developed tool were similar to expert's performance of mold machinist.
