A measuring machine feeds imbalance data of the workpiece to a solution processor. The associated memory defines a model data structure to store the imbalance data and also store data indicative of the geometry of the workpiece, where the model data structure stores workpiece geometry data representing the location of at least one workpiece modification site, referenced to at least one predetermined reference frame. The solution processor is programmed to execute a solver program that seeks at least one solution to reduce the imbalance, using the model data structure as solver constraints. The solution processor outputs at least one solution as imbalance reduction data representing the location of at least one workpiece modification site together with a datum indicative of a weight to be added to or removed from the workpiece at the modification site. A workpiece modification machine has a workpiece modification processor that uses the output of the solution processor to control a machine that physically modifies the workpiece to reduce imbalance, by adding or removing material.

Weight splitting control system

A crankshaft balancer machine for balancing a crankshafts having a measurement station configured to rotate the crankshaft to obtain vibration-related data, a transfer station configured to transfer the crankshaft between the measurement station and the correction station, and a correction station configured to drill at least a portion of the crankshaft to correct an imbalance in response to the imbalance data. The measurement station includes a base structure, a measurement bridge support, a plurality of flexural support legs extending therebetween, at least one sensor, and a drive system to spin the crankshaft and output imbalance data. The transfer station includes at least one lifting arm selectively engaging the crankshaft and supporting the crankshaft during transfer. The correction station includes a drilling device horizontally disposed to achieve a horizontal drill direction into the crankshaft to correct any imbalance according to a customized software protocol.
