Scientific novelty

An innovative technology for improving the surface quality of products made from hard-to-machine materials, based on modifying the surface structure, changing the cutting tool design, and controlling the machining process. The technological effect is achieved through a combination of physical influences (laser and cryogenic treatment, thermoplastic deformation, high-frequency wave action).

Advantages

- effective reduction of vibration amplitude during machining is ensured, allowing for surface quality control of products made from hard-to-machine materials; - the magnitude and frequency of built-up edge formation on the tool cutting edge is reduced when machining products from hard-to-machine materials; - stable chip segmentation and removal from the machining zone is achieved; - machining process efficiency is increased by reducing the number of operations and enabling technology automation.

Commercial implementation

The proposed set of technological solutions can be successfully implemented within machine-building facilities specializing in the manufacture of critical components from hard-to-machine materials. The advantage of this integrated technological solution over analogs is the possibility of its adaptation to specific features of the machining process, taking into account partial or full production automation.
