Embodiment Construction

[0041] The present invention is described in detail below in conjunction with accompanying drawing.

[0042] Such as figure 1 As shown, a three-axis CNC machine tool online error testing system based on laser dot matrix includes a CNC machine tool 1, a laser dot matrix generator 2, a grid positioning board 3, an industrial camera 4, and a computer 5.

[0043] Such as figure 2 As shown, the laser dot matrix generating device 2 is made up of a handle 2-1, a laser generating device 2-2, a grating 2-3 and a grating fixing device 2-4, wherein the grating can convert the single beam light generated by the laser generator into A 3×3 array of nine beams evenly arranged, in which the outermost two beams of each row form an angle of θ with each other. The laser dot matrix generating device 2 is similar to the common cutting tool, and can be placed in the CNC machine tool in the disc and changed to the main shaft by the tool changer provided by the CNC machine tool.
