Non-contact measurement system gear chamfering object coordinate system and system positioning of coordinates of movement platform is to bring laser sensor to move so as to make laser spot to project onto lower left corner point

checkerboard XY mobile platform via manual control

this method has some human error

which increases in system measurement error gear chamfering[1]. Present measurements with using laser displacement sensor to scan calibration plate and the lower edge of the right side of point mutations in the lower right corner location coordinates to determine the calibration board position coordinate information from the lower left corner of the effective area of the checkerboard point between the calibration plate lower right corner is known

control XY motion of two-dimensional motion platform

laser spot is projected onto location of the lower left corner point of checkerboard in active area

complete system positioning.
