Three-coordinate measuring instrument is a high-precision measuring tool, which measures the size, shape and position of workpiece by mechanical and optical means. Its main principle is to measure the workpiece with three coordinate axes, which has the advantages of high accuracy and good repeatability, and is suitable for measuring the workpiece with high dimensional accuracy.
Second, the 3d scanner
3d scanner is a tool to scan an object in three dimensions by laser or optical sensor. Different from CMM, 3d scanner has the function of computer-aided design and manufacturing, and can carry out rapid reverse engineering and complex terrain and surface measurement.
Third, the difference between them.
Although CMM and 3d scanner are both 3D measuring tools, they are obviously different. The main difference lies in the working principle and scope of application.
Three-coordinate measuring instrument is suitable for workpiece measurement with high dimensional accuracy, and can provide high precision and high repeatability measurement results. 3d scanner is suitable for complex terrain and surface measurement and rapid reverse engineering.
In addition, there are differences in usage methods. Three-coordinate measuring instrument needs to put the workpiece on the measuring table, while 3d scanner needs to put the object in the scanning area. Therefore, according to different measurement requirements, appropriate measuring tools can be selected for measurement.
abstract
Coordinate measuring instrument and 3d scanner are common 3D measuring tools, but there are obvious differences between them. Three-coordinate measuring instrument is suitable for workpiece measurement with high dimensional accuracy, while 3d scanner is suitable for complex measurement of morphology and curved surface and rapid reverse engineering. According to different measurement requirements, you can choose a suitable measuring tool to measure.
