Abstract:
1. An interference check device disposed in an apparatus provided with a plurality of moving bodies, which is capable of moving in a predetermined direction, moving devices for moving said plurality of moving bodies, and another moving device for moving at least one of said moving bodies in a same axial line direction as one of the moving devices, said interference check device conducting interference check when said at least one of said moving bodies is moved, and comprising: an absolute movement amount calculating part which synthesizes a movement amount of said at least one of the plurality of moving bodies, which is a subject to be checked; in the same axial line direction based on data inputted for said at least one of the plurality of moving bodies and said plurality of moving bodies, when said at least one of the plurality of moving bodies is provided on a moving table, and is moved on the moving table by one of the moving devices and the moving table is moved in the same axial line direction as the moving body by said another moving device, thereby to determine an absolute movement amount in said same axial line direction; and an interference check part associating with the absolute movement amount calculating part, said interference checking part checking the interference check from said absolute movement amount, wherein said absolute movement amount calculating part synthesizes a plurality of moving axes in the same axial line direction by the plurality of moving devices, provides a virtual axis in the same axial line direction as a moving axis, and obtains said absolute movement amount based on the virtual axis.
