Smooth Acceleration of Transverse Axis Movements in CNC Threading Machining

Popis výsledku v původním jazyce

Most of the complex details of modern technical products are manufactured on CNC equipment. The threaded surface is one of the most critical elements of such parts. Their reliability and durability largely depend on the accuracy of the machining process. Machining threaded surfaces requires precise synchronization of periodic tool movements with the continuous rotation of the spindle. Ensuring smooth movement along the transverse axis with a synchronized approach to the machined surface is one of the important tasks. A variant of solving this problem in a two-level CNC system is proposed. A mathematical model of the movement along the transverse axis with a smooth variation in acceleration has been developed. A technique is proposed using an S-shaped feed profile based on the sin(2) function, which provides ease of calculation and high accuracy. The model is implemented in a two-level CNC. The results of experimental studies are shown that servo error decreases to a value of the order of 0...–1 μm before the end of the approach section, outside the workpiece.
