Influence of Setting Size Control Errors of Thread-cutting Heads with Round Radial Combs on Cutting Conditions
DOI: 10.22184/2499-9407.2025.41.4.44.49
Theoretical studies have been conducted on influence of recommended setting sizes of thread-cutting heads equipped with round radial combs, and the errors in their control, on the pattern of changes in the rake angle and bearing surfaces of the threaded pair, taking into account the kinematic features of cutting and the arrangement of forming elements on the cutting part of the tool. Values of the setting sizes of the thread-cutting head have been obtained that ensure the required rake angles on the elementary cutting profiles of the working part of the tool. The parameters of the thread being cut have been determined under which the possibility of using special means of excess size control, applied in industry, is limited. It has been shown that to ensure the cutting and calibrating part of the tool can perform its functions, selection or design of means for controlling the amount of excess must be carried out taking into account the analytically derived relationship between the structural and geometric parameters of the threaded pair a comb and a workpiece.
