FIELD: process engineering.
SUBSTANCE: proposed method comprises locating the workpiece over its length at centering stocks and feeding the cutter in lengthwise direction. To up the precision working, workpiece is located in inscribed circle in roughing while, in finishing, in circumscribed circle. Centering stocks are located in zones of workpiece nodal patter formation. Note here that coordinates of stock and workpiece contact points are set proceeding from the condition of the absence of pressure to workpiece location surface. In machining, workpiece axis is controlled by switching of centering stocks to stepwise variation of aforesaid coordinates at workpiece diameter decrease at cutter displacement by the stock under conditions of electric isolation of the cutter and the tool.
EFFECT: higher location accuracy.
