英语翻译随着科学技术的发展和社会需求的多样化,产品的竞争越来越激烈,更新换代的周期也越来越短.为此,要求不但能根据市场的

With the development of modern society and the diversity of socity demand, production competiton is getting fiercer and fiercer and update cycle is becoming shorter and shorter。Therefore ,in this situation we are demanded not noly to design new productions according marketplace , but also to manufacture its origin in the shortest possible time which is used to performance test and modification and finally form stereotypes products。 However, in the traditional manufacture system,it needs massive work of mold design,manufacture and modification whose cost is quite high and whose cycle is quite long ,so it is very difficult to adapt to the rapid marketplace changes 。In order to improve the research and development and production speed to manufacture high -quality and low -cost molds and productions so as to respond quickly to market changes, people has made a lot of research and exploration。 With the maturing of the laser processing technology and gradually decreasing price of the industrial use of high-power laser equipment , a significant reform has brought to mold manufacturing technology。 Laser processing as advanced manufacturing technology has widely applied to many important national economy departments like automotive, eletronic, eletrical, aviation, metallurgy, machinery manufacturing and so on and has palyed a more and more important role in improving production quality ,labour productivity,automation,non-pollution and decreasing material consumption 。This article has made a deep discussion about mold manufacturing ,mold surface strengthening and repairing ,cleaning ,replacing and so on several aspects through the understanding in the principles ,advantages and features of the laser processing technology combined with the present situation of mold manufacture。
