Coordinate Measuring Machine

A coordinate measuring instrument refers to an instrument capable of expressing measurement capabilities such as geometric shapes, lengths, and circumferential divisions within the space of a hexahedron. It is also called a coordinate measuring machine or a coordinate measuring bed. The CMM can also define "a detector with three directions of movement, which can be moved on three mutually perpendicular guides. This detector transmits signals in a contact or non-contact manner, and the displacement of three axes A measuring system (such as a grating ruler) calculates each point (x, y, z) of the workpiece and an instrument for measuring various functions through a data processor or a computer. " The measurement functions of the CMM should include dimensional accuracy, positioning accuracy, geometric accuracy, and contour accuracy.
