This paper presents a measuring technique and a data-processing algorithm for conical taper parts. Applied in this research are the measuring method of radial deviation and the 10mm range digital transducer with 0.1μm resolution. The acquired data involve the tilting and eccentric errors. It is, however, very hard to remove these errors because the formulae for this problem become nonlinear. Then this paper proposes a newly developed algorithm iterating the linear regression formulae in the least square method. This algorithm is simplified and rationalized for a micro-computer processing.
