Compensation of the deviations caused by mechanical deformations during machining of threads

In the paper deviations during threading caused by mechanical deformations are analysed. Machining with full and partial profile of the cutting insert is investigated. A new method for inspecting the machined thread profile is suggested where the profile deviations caused by mechanical deformations can be compensated. The method is based on a workpiece-cutting tool touch probe inspection system. A detailed description is given on the cutting tool setup and monitoring algorithm for threading inserts with both full and partial profiles. The method can be applied to all types of internal or external threaded surfaces.
