Purpose. Search for promising ways to intensify of the GTE discs and shafts hard materials turning. Analysis of the scientific advances in this field. Specification purpose of scientific research aimed at the intensification of turning.
Design/methodology/approach. The problem of increasing the efficiency of the GTE disks and shafts production through the intensification of the turning is still relevant because of the tendency of materials used in aircraft engine. With regard to the manufacturing processes of the gas turbine engines discs and shafts, the proportion of turning operations in the structure of some of them reaches 60%. The authors offer the phenomenological model of the intensification of difficult to cut materials turning and describe in short the basic methods of the cutting process improving. A review of the progressive combined machining methods of difficult to machine materials detects the presence of significant shortcomings. For a more elegant technical solution proposed the method of the direct control of contact and thermal phenomena for intensification of the difficult to cut materials turning.
Findings. In order to intensify the turning of the GTE discs and shafts necessary to investigate the possibility of implementing the method of direct control of contact and thermal phenomena during processing.
Originality/value. The phenomenological model of the intensification of difficult to cut materials turning is offered. The purpose of scientific research aimed at the intensification of turning is specified.References
