Title: Apparatus and method for measuring coordinates for pressing mold
Inventor: MORIYA TAKASHI
IPC: G01B21/00
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To directly measure the coordinates of a molded product by attaching an angular distance-measuring means to a guide post of a pressing mold and detecting the distance to the measuring point and the angle in the XY plane. SOLUTION: The angular distance measuring means 1 is attached to the guide post of a pressing die and a wire for measurement is laid between the guide post and the measuring point to measure the length L of the extended wire for measurement and the angle α of the measuring point in the XY plane. A circle coordinate-computing means 3 computes the coordinate expression of a circle from the length L and the angle α and transmits it to the shape-computing means 4. The shape-computing means 4 computes three-dimensional coordinates of crossing points from the coordinate expression of a circle and three dimensional CAD data housed in a memory means 2 and uses the coordinates as that of the measuring point.  These processes are carried out for every measuring point and the three-dimensional coordinates for each measuring point are compared with one another to judge the flowing state of a material. Consequently, without requiring a pressing mold to be moved, measurement is carried out while using the molding mold as it is in the work field in pressing process.
