COMBINED METHOD OF TURNING PLASTIC WORKPIECES Russian patent published in 2017 - IPC B29C37/00 B29C39/30 B29C59/02 

FIELD: technological processes.

SUBSTANCE: according to the method of turning plastic workpieces, the workpiece and the cutting tool are imparted the relative motion of forming and the feeding is carried out discretely. Herewith pre-treatment of the plastic workpiece is carried out by twisting it to a tangential stress value of not more than 0.8 of the tensile strength of the workpiece material. Twisting of the workpiece is carried out in the direction opposite to the direction of the workpiece rotation during turning.

EFFECT: increasing the productivity and quality of processing the workpiece, receiving the set physical and mechanical properties of products.
