Sleeves Size Testing With Coordinate Measuring Machine
The Coordinates measuring instrument can be defined as a kind of can make three direction of the detector, can be in three perpendicular guide rail, the detector to contact or non-contact transmission signals, such as three axis displacement measurement system (such as optical ruler) by the data processor or calculation work pieces, such as computers, each point coordinates (X, Y, Z) and various functions of measuring instruments. The measurement function of CMM should include dimensional accuracy measurement, positioning accuracy measurement, geometric accuracy measurement and contour accuracy measurement, etc. Any shape is composed of three-dimensional space points, and all geometric measurement can be summed up as the measurement of three-dimensional space points. Therefore, accurate collection of space point coordinates is the basis of evaluating any geometric shape.
