FIELD: technological processes.
SUBSTANCE: method includes definition of cut contours by contours of side walls and/or bladed channels, further removal of material by drilling from blank in places of interblade channels location, and after drilling - final milling of interblade channels location by means of material removal left in interblade channels. In process of interblade channels drilling material is removed by drill in direction of gas flow in interblade channel, and axes of openings are installed approximately parallel to direction of gas flow in interblade channel drilled in blank.
EFFECT: increased efficiency of processing.
