Crankshaft Shape Inspection Method, Computation Device, Program, And Shape Inspection Device
Abstract: This crankshaft shape inspection method comprises: a first step for acquiring three-dimensional point cloud data for the surface of a crankshaft S; a second step for superimposing the three-dimensional point cloud data over a surface shape model of the crankshaft S; a third step for moving the three-dimensional point cloud data that has been superimposed over the surface shape model so as to match the coordinate system at the time of crankshaft S machining; a fourth step for generating, within the coordinate system at the time of crankshaft S machining, an estimated machined surface that will be the surface after the machining of a predetermined machining region of the crankshaft S; and a fifth step for calculating the distance between machining region point cloud data extracted from the three-dimensional point cloud data after the movement in the third step and the estimated machined surface generated in the fourth step and determining a machining allowance insufficiency for the crankshaft S on the basis of the calculated distance.
