我厂在为航天部加工某产品的部件时(工件如图1所示),由于批量较小,专门设计制作了一种“切余料定位装置”(如图2所示)。经过一段时间的使用证明,它不但安全可靠,实用性强,效果良好,而且加工质量也得到明显提高,良品率达到100％,工效提高约4～5倍,经济效益也大幅度增长。 I plant in the Ministry of aerospace processing a product parts (the workpiece shown in Figure 1), due to the smaller batch, specially designed and manufactured a “surplus material positioning device” (Figure 2). After a period of use proved that it is not only safe and reliable, practical and effective, and the processing quality has also been significantly improved, yield of 100%, work efficiency increased by about 4 to 5 times, and substantial economic growth.
