The Function and Significance of Three-dimensional Measurement

The industry has made great progress since the 1960s. With the rise of industrial production machinery, automobiles, aerospace and electronics industries, the development and production of various complex objects require advanced detection technology and instruments, which are reflected in the three coordinate measuring machine and three-dimensional measurement technology came into being, and have been rapidly developed and improved.

The appearance of coordinate measuring machine is a milestone of the transition of measuring instrument from classic manual method to modern automatic testing technology. CMM plays an important role in 3D measurement technology in the following aspects:

1. It solves the problem of measuring the aperture and hole position of the box parts, blades and gears, automobiles and aircraft.

2. The accuracy of 3D measurement is improved. At present, the accuracy of high-precision CMM can reach less than 1um. For the CMM used in workshop inspection, the measurement accuracy of each axis can reach 2um. The accuracy of DIPSEC produced KYUI series CMM can reach 0.75um.

3. CMM can be combined with CNC machine tools and machining centers to form production lines or flexible manufacturing systems, which promotes the development of automated production technology.

4. With the continuous development of automation technology, the measuring efficiency of CMM has been greatly improved.
