METHOD FOR MEASURING TEMPERATURE AND POWER PARAMETERS IN PROCESS OF CUTTING WHILE DRILLING Russian patent published in 2024 - IPC B23B49/00 B23Q17/09 

FIELD: processing materials by cutting.

SUBSTANCE: invention is intended for measuring the temperature and power parameters of the cutting process during drilling, also supplying lubricating media (LM) in the form of an aerosol, watering, and also a jet under pressure into the cutting zone when using metal-cutting tools with internal channels for supplying LM. The method includes electrically isolated fastening of a metal workpiece in a lathe chuck and processing of the workpiece using a drill electrically isolated from the machine, fixedly mounted on a stand mounted on the machine support, during which thermo-EMF is measured using a personal computer comprising Power Graph Professional software, connected to an amplifier and an analogue-to-digital converter, in turn, the amplifier is connected to an electrical wire made of tool material, with a natural thermocouple junction placed in a container with ice, formed by electrical wires from the tool and material being processed, attached to the drill and to the current collector, electrically associated with the workpiece. The fastening elements of the drill together with it are installed in a housing that also comprises a linear bearing, fixed in the housing using retaining rings, configured for rotation and axial movement of the drill, connected through a mandrel and a metal adapter with a metal stop fixed in the electronic dynamometer. A system for supplying LM to the cutting zone during blade processing using metal-cutting tools with internal supply of LM has also been implemented. The use of this technical solution makes it possible to expand the process capabilities of the invention through the additional ability to measure the axial cutting force.

EFFECT: expanding the scope of application of animal fats in metalworking and possibilities for the use of LM, while providing the necessary parameters of the gas-oil mixture.
