METHOD AND DEVICE FOR CONTROL OF THERMOELEMENT Russian patent published in 2021 - IPC B23B1/00 

FIELD: high-speed details machining.

SUBSTANCE: invention relates to the field of high-speed details machining on equipment with numerical control (CNC), in particular to devices for increasing productivity during machining by controlling the cooling of the cutting tool. To increase the speed of the thermoelement control process and increase the speed of machining details on CNC machines, the thermoelement control device contains a temperature sensor in the cutting zone, a product feed rate sensor, a cutting speed sensor, a part, a tailstock, a headstock, a cutting plate, a box with a Rose's alloy, a Peltier element, a holder, a power source, a DC generator containing a resistor, a bipolar transistor, an operational amplifier, a potentiometer, a programmable logic integrated circuit, consisting of a current-to-voltage conversion unit and a current calculation unit, a computer. The thermoelement control method calculates the current strength to control the cooling of the cutting plate using the Peltier element.

EFFECT: invention increases the speed of the thermoelement control process and increase the speed of machining details on CNC machines.
