Process control methods are developed that leverage compliant robot control, CAD model data extracts, self-acquired surface geometry measurements, and strategy based programming to finish grind cast turbine blades. The processes achieve high finishes, accommodate varying work needs, and require only a brief teaching session to program for new parts.
Impediments to robot usage in manufacturing settings that arise from position-oriented control are identified. Process methods that leverage compliant robot control together with CAD model data and strategy based programming are shown to help overcome these impediments. The techniques are shown in the context of automating finish grinding of cast turbine… (More)
