Abstract
A conical workpiece length measurement method is provided. Two laser displacement sensors are symmetrically arranged at opposite sides of a to-be-measured conical workpiece or a tooling loaded with the to-be-measured conical workpiece. Distance Xfrom each displacement sensor to a bottom plane of the to-be-measured conical workpiece is calibrated. An elongated base plate is arranged at a tip of the to-be-measured conical workpiece, and the two displacement sensors measure their respective distances to the base plate. The total length of the to-be-measured conical workpiece is calculated as follows: X=X+(X+X)/2, where Xrepresents distance from one of the two displacement sensors to the base plate, and Xrepresents distance from the other of the two displacement sensors to the base plate. Factors influencing the length measurement include calibration of the fixed length, measurement accuracy of the displacement sensor and a tilt error of the base plate.
