Application of Support Vector Regression in assessment of geometric errors

International Journal of Manufacturing Research (IJMR), Vol. 3, No. 2, 2008

Abstract: Manufactured components are verified using Coordinate Measuring Machine (CMM) and form-measuring instruments or setups. Standards define form error based on a Minimum Zone (MZ) principle which establishes an ideal reference feature. This principle is extended in the present work to arrive at the relationship errors. Additionally, idealisation of relationship has been attempted for the first time. Support Vector Regression (SVR) technique is used to evaluate form and relationship errors from CMM and form data. For new data sets and data taken from literature, the results show that SVR method can produce unique parameters for MZ.
