近年来,数控技术在机械加工中迅速发展起来。由于数控机床价格昂贵,制造维修困难,因此普遍采用数控机床有很大困难。而在普通机床上安装上数字显示装置,也可以达到自动测量与自动定位的目的。数显装置是一种见效快、费用少、制造维修方便、能提高产品质量、提高劳动生产率、减轻工人劳动强度的一项有效措施。随着科学技术的发展,机械工业中的测量技术已从第一代的机械测量、第二代的光学测量,发展到了第三代的自动测量,自动测量的结果,可用数
In recent years, CNC technology in the rapid development of machining. Due to the high cost of CNC machine tools, manufacturing and maintenance difficulties, it is widely used CNC machine tools have great difficulties. In the ordinary machine installed on the digital display device, you can also achieve the purpose of automatic measurement and automatic positioning. Digital display is a quick, inexpensive, easy maintenance, can improve product quality, improve labor productivity, reduce labor intensity of workers is an effective measure. With the development of science and technology, the measurement technology in the machinery industry has developed from the first generation of mechanical measurement, the second generation of optical measurement, to the third generation of automatic measurement, the result of automatic measurement, the available number
