Spraying robot system and spraying method wherein spray conditions are determined by using computer

摘要

An object of the present invention is to provide a thermal spraying robot system capable of automatically determining spraying conditions according to the shape of a workpiece. Shape data on a workpiece (9) and material data on a thermal spray material are entered by operating a data input unit (1). A spray condition database 3 stores a plurality of spray parameters for kinds of thermal spray materials and for qualities of sprayed coatings. A path calculating unit (4) selects values of spray parameters from the spray condition database (3), and then calculates a path for a thermal spraying gun (14) according to a predetermined program on the basis of the shape data on the workpiece and the selected values of the spray parameters. The path calculating unit (4) decides whether or not a thermal spraying operation can be carried out by moving the thermal spraying gun along a calculated path. If it is decided that the thermal spraying operation is feasible, a thermal spraying apparatus 10 carries out the thermal spraying operation in which the thermal spraying gun is moved along the calculated path.
