Abstract

FIELD: mechanical engineering, machining. SUBSTANCE: cutting tool consists of holder and cutting member in the shape of plate. The plate has insert going out on back auxiliary surface of cutting plate. The insert is made of material having higher intensity of gas escape in the cutting process in comparison to main material of plate and is mounted perpendicular to front surface of plate. Insert width is less than length of admissible maximal wear of tool back surface. Insert height is less or equal to plate height but more than value of admissible critical wear along auxiliary surface. Distance between tool top and right edge of insert is less or equal to length of admissible maximal wear of tool back surface. Insert can be disposed parallel to tool main axis. EFFECT: enhanced accuracy of processing due to possible control of wear value of cutting tool in the course of cutting process.

Изобретение относится к машиностроению, в частности к обработке металлов резанием. В режущем инструменте, состоящим из державки с режущим элементом в виде пластины, пластина выполнена с вставкой, выходящей на заднюю вспомогательную поверхность режущей пластины. Вставка выполнена из материала с более высокой интенсивностью газовыделения в процессе резания по сравнению с основным материалом пластины и установлена перпендикулярно передней поверхности пластины. Ширина вставки меньше длины допустимого максимального износа задней поверхности инструмента и высота вставки меньше или равна высоте пластины, но больше величины допустимого критического износа по вспомогательной поверхности. Расстояние между вершиной инструмента и правой гранью вставки меньше или равно длине допустимого максимального износа задней поверхности инструмента. Вставка может быть расположена параллельно основной оси инструмента. Режущий инструмент позволяет повысить точность обработки за счет обеспечения возможности контроля величины износа режущего инструмента в течение всего процесса резания.The invention relates to mechanical engineering, in particular to the processing of metals by cutting. In the cutting tool, consisting of a holder with a cutting element in the form of a plate, the plate is made with an insert facing the rear auxiliary surface of the cutting plate. The insert is made of a material with a higher gas evolution during cutting compared to the main material of the plate and is installed perpendicular to the front surface of the plate. The width of the insert is less than the length of the permissible maximum wear of the rear surface of the tool and the height of the insert is less than or equal to the height of the plate, but more than the value of the critical wear on the auxiliary surface. The distance between the top of the tool and the right edge of the insert is less than or equal to the length of the maximum allowable wear on the back surface of the tool. The insert may be parallel to the main axis of the tool. The cutting tool allows you to increase the accuracy of processing by providing the ability to control the amount of wear of the cutting tool during the entire cutting process.
