Abstract
On the basis of location information which signifies a clamp location of a jig with respect to a new workpiece, new workpiece cross-section information is recognized in the clamp location. Next, a search is carried out among existing workpiece cross-section information for information similar to the recognized new workpiece cross-section information. Next, jig information is selected which is linked to the found workpiece cross-section information. Next, the selected jig information and the location information are linked and set to new workpiece design information.
Claims4
A jig information setting method of setting jig information of a jig for supporting a new workpiece, with respect to design information of the new workpiece for a welding operation, the method performed by a processor, comprising:
- a cross-section information recognition step of recognizing new workpiece cross-section information at a clamping position of the jig, based on positional information indicative of the clamping position;
- and
- a jig information setting step of retrieving information similar to the new workpiece cross-section information from existing workpiece cross-section information, selecting the jig information associated with the existing workpiece cross-section information retrieved, and setting the selected jig information and the positional information in association with each other to the design information,
- wherein the new workpiece cross-section information contains information about coordinates of a center of gravity of a cross section of the new workpiece, information about a normal vector of the cross section of the new workpiece, and information about a shape of the cross section of the new workpiece,
- wherein the existing workpiece cross-section information contains information about coordinates of a center of gravity of a cross section of the existing workpiece, information about a normal vector of the cross section of the existing workpiece, and information about a shape of the cross section of the existing workpiece, and
