The purpose of the invention is to increase the productivity in rotary processing by optimizing the cutting mode. The drawing shows a graph of the change in cutting temperature from the ipocTH rotation of the workpiece and the ratio of the rotation speeds of the tool and billet, to clarify the implementation of the proposed method of processing with optimization of cutting conditions for the minimum cutting temperature. Example. From steel 50 with a diameter of 120 mm with a rotary cutter made of hard alloy VK8 with a diameter of 50 mm on a 16K20 lathe using a device for rotational cutting. Geometry of the cutting part of the tool. Elements of cutting mode, 5-3.0 m / s. W mm / rev; The cutting temperature was measured using a natural thermocouple. During processing, the rotational speed of the workpiece was changed to a value corresponding to the optimum cutting temperature, such as the temperature of the structural phase transformation () in the material being processed (curve 1 in the drawing), and at the same time The rotational speed of the cutter was adjusted, while the ratio of the Vp / V ratio was from 0.2 to 0.6. In this interval, the value of the optimal ratio of the rotation speeds of the cutter and the workpiece was determined, corresponding to the minimum cutting temperature (curve 2 in the drawing) and the optimum cooling conditions for the rotary cutter. The proposed optimization of the rotational speed of the workpiece and the ratio of the speeds of rotation of the cutter and the workpiece according to the cutting temperature provides an increase in the durability of the cutter, the number of parts machined by it and, consequently, the processing performance.
