1.三座标测量机的定义三座标测量机是近十几年来新发展的一种高效率精密测量仪器,它被广泛用于机械制造、仪器制造、电子工业、汽车和航空工业中,测量各种机械零件、模具等的形状尺寸、孔的位置、孔的中心距以及形状复杂的轮廓。按日本的定义,这种测量机在 X、Y、Z 方向一般均有导向机构,并在各座标上设有测量座标移动距离的测长元件和读数装置,同时具有放置工件的工作台,测量头可以用手或机动轻快地移到测量点上,通过数显装置就能将各方向的座标值显示出来。如果在这种测量机上加上诸如分度头或万能转台之类的附件,它还能在四个或五个座标轴上测量零件。很早以前就有各种各样的座标测量机。例如测长机,它用来在一个方向上测量工件
1. Definition of Three Coordinate Measuring Machine Three coordinate measuring machine is a newly developed high efficiency precision measuring instrument in recent ten years. It is widely used in machinery manufacturing, instrument manufacturing, electronics industry, automobile and aviation industry, Measurement of various mechanical parts, molds and other shape and size, the location of the hole, the hole center distance and the shape of the complex contour. According to the definition of Japan, this measuring machine in the X, Y, Z direction generally have a guide mechanism, and coordinates in each coordinate measuring distance measuring elements and reading devices, while the table has a workpiece placed , The measuring head can be moved by hand or by maneuver to the measurement point lightly, and the coordinate values in all directions can be displayed through the digital display device. It also measures parts on four or five axes if such measuring machines are equipped with attachments such as indexing heads or universal turntables. A wide variety of CMMs existed long ago. For example, length measuring machine, which is used to measure the workpiece in one direction
