多品种,中小批量的生产,无论从科技发展速度还是市场经济来看,它已是各国机械工业生产的主体(占各国机械工业总产值的百分之七十左右)。为了适应这一形势的需要,各国均加速了“成组技术”的推行。 根据国内外资料统计,GT使生产效率平均提高了百分之三十五——五十。据国际机械加工技术研究学会(CIRP)的调查。预测到一九九○年全世界将会有百分之七十五的机械加工企业采用GT。但应说明,作为一个机械工业产品,在整个产品零件中,根据ABC分类
The production of multiple varieties and medium and small batches, no matter from the speed of technological development or the market economy, it is the main body of machinery industry production in various countries (accounting for about 70% of the total output value of the machinery industry in various countries). In order to meet the needs of this situation, all countries have accelerated the implementation of “group technology.” According to statistics at home and abroad, GT has increased production efficiency by an average of 35% to 50%. According to the survey of the International Association for Mechanical Processing Technology (CIRP). It is predicted that by the year of 1990, 75% of the world’s machining enterprises will adopt GT. But it should be stated that as a mechanical industrial product, in the entire product part, according to ABC classification
