一、前言日本经济增长是以确立汽车、家用电器为代表的耐用消费品的大批量生产体制为基础的。在这种体制后面支撑着批量生产技术的是模具工业,是用模具进行冲压或塑料成形加工的单一品种的大量生产方式。但是,由于机械零件越来越复杂和多样化,且产品寿命缩短。因此,大量生产制件的方式,被迫转向适应产品更新换代的多品种中、小量生产方式。模具行业对此迅速作出反应,从过去依靠仿形机床、通用电加工机床、手工精加工的工业技术形态,转向以使用数控和计算机的模具加工自动化技术为中心的高度机械化工业。
I. Preface Japan’s economic growth is based on the mass-production system of durable consumer goods represented by automobiles and household appliances. Behind this system is to support mass production technology is the mold industry, the mold is used for stamping or plastic forming a single species of mass production. However, due to the ever-increasing complexity and variety of mechanical parts, the product life expectancy is reduced. Therefore, a large number of production methods of parts, forced to shift to adapt to the replacement of more varieties of medium and small production methods. The mold industry responded quickly by moving from a past industrial form of profiling, general-purpose machining and manual finishing to a highly mechanized industry centered around the use of CNC and computer-based tooling automation.
