Abstract
A system and method for manufacturing and/or reconditioning side frames and bolsters for railway cars includes at least one robot adapted to access positions along the length of the part. A map of the part dimensions, which may be obtained by a probe or scanner on the robot(s), allows a processor to determine where welding and machining are required to meet certain dimensional tolerances, leveraging novel reference surfaces on the part which cannot be leveraged using conventional gauges. The robot(s) may locate and mount welding and material removal tools to carry out the welding and material removal operations determined by the processor.
