随着社会需要和科学技术的发展,产品的竞争愈来愈激烈,更新的周期越来越短,因而要求设计者不但能根据市场的要求很快地设计新产品,而且能在尽可能短的时间内制造出产品的样品,进行必要的性能测试,征求用户的意见,并进行修改,最后形成能投放市场的定型产品。用传统方法制作样品时,需采用多种机械加工机床,以及工具和模具,还要有高水平的技工,既费时,成本又高,周期往往长达几星期甚至几个月,不能适应日新月异的变化。为克服上述问题,
With the social needs and the development of science and technology, the increasingly fierce competition in products and the shortening of the renewal cycle, designers are required not only to design new products quickly according to the requirements of the market, but also to be as short as possible Time to create a sample of the product, perform the necessary performance tests, solicit user comments, and make changes to finalize the final product that can be placed on the market. When using traditional methods to produce samples, a variety of machining tools, tools and molds are required, as well as a high level of mechanics, which is time-consuming and costly. The cycles are often weeks or even months and can not be adapted to ever-changing Variety. To overcome the above problems,
