The orientation and location of machined surfaces in three-dimensional space are important for the function of many car chassis components. Vectorial Tolerancing (VT) is mathematically unambiguous model for describing nominal and actual geometry as well as tolerances using three-dimensional orientation and location vectors. VT is particularly useful to control the three-dimensional orientation and location deviations of a machining process. This paper describes how VT can be used to control the machining process in the manufacturing of one specific chassis control arm at Raufoss Technology. Multivariate Statistical Process Control (SPC) is used since there is more than one parameter for each surface. Correction is made by mirroring the calculated sample means onto the nominal means. The quality characteristics on one surface are correlated. Multivariate Process Control is therefore used. A Multivariate SPC of the orientation deviation on a bushing boring on a automotive wheel suspension control arm was shown.
