The threaded surface is an important element of various technical products, such as leadscrew, worm drive, high-pressure gas, oil tubing, etc. The accuracy of the manufacture of the threaded surface largely determines its reliability and durability. Threaded surface machining on CNC equipment requires accurate synchronization of the periodic movements of the tool with the continuous rotation of the spindle. One of the possible options for organizing such synchronization in a two-level CNC system is observed. Mathematical models of movement at the acceleration stage of the longitudinal movement axis synchronized with the spindle have been developed. Models based on uniformly accelerated motion and motion with a smooth change in differential characteristics such as speed, acceleration, and jerk are considered. An S-shaped feedrate profile using the sin2 function is applied. The movement of the longitudinal axis at thread machining is synchronized with the position of the rotating spindle. The problem of axis acceleration at synchronized movement on a section of a given length with the implementation of an S-shaped feed profile is solved. The proposed model is implemented in the two-level CNC. The results of its experimental studies are presented.
