The article presents an analytical description of the threaded coupling between the tool and the workpiece as a complex geometric object characterised by specific manufacturing precision. We analyse the extent to which components of manufacturing imprecision in the tool cutting edge affect thread cutting dynamics. The study shows that the radial force component that depends on the effective thread diameter deviation proper is the most significant one for taps of all tolerance classes. We consider the possibility of computing dynamic properties based on the actual thread profile outline, to be used at the design stage for standardising manufacturing precision of surface-shaping points of the threading tool implementing a nibbling cutting pattern.
