塑料瓶凹模型腔的数控加工 摘要 随着现代机械行业的发展，机械自动化程度越来越高.各种先进的机械加工设备和机械加工工艺让给现代制造业有了长足的发展。随着人们物质生活的提高，对产品的多样性及实用性提出要求，一部分新产品的设计任务就交给了机械工作者。现代生活中人们对于塑料制品的需求越来越大，而且对塑料制品的外形结构与工艺水品提出了更高的要求。这就要求设计人员能够熟练运用注塑模具的设计知识以及模具的生产加工知识.其中包括数控加工技术和计算机辅助制造（CAM），以及各种二维和三维辅助设计软件的应用.在设计过程中要不断发现错误,修改尺寸参数,以求设计出符合质量要求以及工艺要求的产品来.设计出来的注塑模具要满足生产需要.也要便于模具的生产加工.在模具的加工过程中要合理选择加工参数保证模具的加工精度,尤其是表面粗糙度.表面粗糙度对模具的质量影响非常大,因此一定要把握好模具制造的质量，制造出符合要求的产品来。 关键词：凹模 加工工艺 编程 Plastic bottles of nc machining sunken model cavity ABSTRACT Along with the development of modern machinery industry, mechanical automation degree taller. Various kinds of advanced mechanical processing equipment and the machining process to modern manufacturing industry has developed rapidly. As people material life enhancement, to diversity of products and practical request, part of the new product design task was relegated to the mechanical workers. Modern life people for plastic products demand is bigger and bigger, and the appearance of plastic products structure and process water product put forward higher request. This requires design personnel proficient in injection mould design knowledge and mold production processing knowledge. Including nc machining technology and computer aided manufacturing (CAM), and various 2d and 3d cad software applications. modify the size parameters, in order to design a to meet the quality requirements and technical requirements of products to the plastic mould. Designed to meet production needs. In the mold processing process be reasonable choice processing parameter guarantee machining precision of the mould, especially the surface roughness of surface roughness to mold. The quality is very large, so certain influence to grasp mould manufacturing quality, create to meet the requirements of products.
