摘要： A method of machining a workpiece after preheating consists in that the workpiece material to be removed by a cutting tool is subjected immediately before the removal operation to intense localized heating and notching by a plasma jet, with a groove being formed on the surface to be machined. To this end, a plasma torch is positioned ahead of the cutting tool so that the angle between the direction of the cutting speed and the plasma jet axis ranges from 0 to 45 degrees, and the angle between the direction of feed of the cutting tool and the plasma jet axis from 10 to 45 degrees.
