The three-axis displacement measurement system ( Such as optical ruler) through the data processor or computer to calculate the coordinates (X, Y, Z) of each point of the workpiece and the instrument for measuring various functions. The measurement function of the three-coordinate measuring instrument should include dimensional accuracy, positioning accuracy, geometric accuracy and contour accuracy.

However, using a three-dimensional coordinate measuring instrument to measure the installation hole position and the important installation support surface, it is necessary to place the workpiece on the ground and then determine a coordinate position point on the workpiece. According to the selected coordinate position point, use The three-dimensional coordinate measuring instrument measures the mounting holes and supporting surfaces required to be detected on the workpiece, and then performs coordinate conversion on the measured relevant dimensional data to determine whether each dimension is within the allowable dimensional tolerance range. This measurement method is used in the measurement Sometimes it is difficult to locate parts, and the coordinate conversion needs to be performed many times during the measurement process, the measurement efficiency is low, and it is difficult to meet the production requirements.
