Field Robustness Evaluation of Products Incorporating Linear Encoders

Abstract

Adhesive technology is often used to attach the scales of linear encoders used in precision measuring equipment, in order to reduce size and weight. If the design and adhesive conditions are not robust with respect to external disturbances, however, poor accuracy may occur. We therefore conducted an experiment aimed at minimizing the error in a dynamic characteristic with zero point proportionality. Although optimization of the bonding conditions was achieved, problems remained such as discrepancies between the results and the S/N ratio under zero-point proportionality.
