摘要：

This paper presents mathematical techniques capable of recovering the profile of twin screw rotors. In a case study a rotor is recovered from scrap, using only measured data. The same techniques may be used in analysis of production errors or in paring male and female rotors. The methodology consists of step wise refinement of the description. Simple means suffice to find the overall dimensions. A statistical estimator provides the parameters of a theoretical model of the profile. Finally, a set of fitted polynomials eliminates systematic productions inaccuracies. Together they provide an accuracy within the size of the leakage paths.
