In the weight correction of workpieces prior to finish-machining, such as connecting rods, the dimensions of the pre-machined surfaces are measured and employed as a factor in the adjustment of the machine tool for weight correction of the workpieces, for example, by machining material off or adding material onto the workpiece, so that the workpiece will have the desired weight characteristics after final machining.
