On the basis of the requirements on design and measurement of the cam lifting, the author expounded the dualism of the cam lifting and analyzed the advantages and disadvantages over existing measuring methods of cylindrical cam lifting. A cam lifting error measuring method has been put forward based on tertiary sample functional combinations. Theoretical analysis and comparing with measuring test results are shown that the measuring precision using this method is high.
