Изобретение относитс к механической обработке материалов, в частности к исследованию изнЬсоустойчивости режущих инструментов, и может использоватьс в области металлообработки дл непрерывного измерени термотока, протекающего через различные участки режущей кромки сверла и последующего определени закономерностей процесса износа инстру мента, св занных с термоэлектрическими влени ми при резании металлов.The invention relates to the machining of materials, in particular to the study of the wear resistance of cutting tools, and can be used in the field of metal processing for continuous measurement of the thermal current flowing through different parts of the cutting edge of the drill and the subsequent determination of the patterns of tool wear associated with cutting effects. metals.
Известен образец дл исследовани процесса сверлени путем измерени термотока, содержащий несколько металлических пласти.н и слои злектроизол цйи , расположенные между ними 1.A known sample for investigating the drilling process by measuring a thermal current, containing several metal plates and electrolytic layers located between them 1.
Однако достоверность исследовани процесса сверлени с этим образцом недостаточна из-за вли ни трибоэлектрических влений - возбуждени электропотенциалов в слоистой структуре образца за счет трени .However, the reliability of the study of the drilling process with this sample is insufficient due to the influence of triboelectric effects — the excitation of electrical potentials in the layered structure of the sample due to friction.
Наиболее близким по технической сущности к изобретению вл етс образец дл измерени термотока при сверлении металлов, содержащий основание и два установленных наThe closest to the technical essence of the invention is a sample for measuring the current flow when drilling metals, containing a base and two mounted on
нем конгруэнтных полых металлических элемента и размещенный между ними слой электроизол ции 2.there is a congruent hollow metal element and an electrically insulating layer 2 placed between them.
Однако точность измерени термотока этим образцом недостаточна, так как при сверлении измер ют термоток, протекающий между двум участками режущей кромки и термоток между сверлом и образцом только в However, the accuracy of the measurement of the thermal current by this sample is insufficient, since during the drilling, the thermal current flowing between the two sections of the cutting edge and the thermal current between the drill and the sample is measured only in
0 одной точке.0 one point.
Цель изобретени - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.
Эта цель достигаетс тем, что элементы выполнены в виде усеченных This goal is achieved by the fact that the elements are made in the form of truncated
