Abstract
In some embodiments, a system uses a two-dimensional polar plot to analyze imbalance of components. On the two-dimensional polar plot imbalance magnitude and orientation are depicted relative to a reference. Some embodiments use the two-dimensional polar plot to assess measurement error for measurement devices and components. Some embodiments use the two-dimensional polar plot to determine patterns associated with processing operations to identify sources of imbalance from the manufacturing process. Some embodiments use the two-dimensional polar plot to determine correlations between processing operations to identify sources of imbalance.

A balance assessment system comprising:
- a balance measurement system;
- a processor in communication with the balance measurement system;
- and
- a memory storing instructions that, when executed by the processor, configure the apparatus to:
- measure, via a balance measurement system, a plurality of components after a first operating process to obtain a first group of imbalance measurements, wherein each imbalance measurement comprises a magnitude and an orientation;
- measure the plurality of components after a second operating process to obtain a second group of imbalance measurements;
- generate a polar plot comprising the first group of imbalance measurements, the second group of imbalance measurements, and vectors connecting measurements from the first group of imbalance measurements and the second group of imbalance measurements that correspond to a same component;
- determine a correlation factor between the first group of imbalance measurements and the second group of imbalance measurements based on an average length of the vectors;
- determine that the first operating process drives an imbalance present after the second operating process when the correlation factor exceeds a threshold;
- and
- generate a report identifying the first operating process as a source of imbalance when the correlation factor exceeds the threshold.
