Abstract

FIELD: jewelry working. SUBSTANCE: method involves recording acoustic emission signals from working zone; finishing surfaces of diamond, with criteria based on values of measured acoustic emission signals being taken into account. Apparatus has diamond orienting mechanism and acoustic emission recorder connected to indication system and formed as piezoelectric element which is in acoustic contact with diamond. According to first variant, piezoelectric element is fixed on diamond orienting mechanism and according to second variant, orienting mechanism is fixed on working members of table body. EFFECT: increased efficiency, reduced processing time, increased precision of diamond orienting during working and provision for automated process. 5 cl, 6 dwg

Изобретение относится к технологии обработки ювелирных камней, может быть использовано при создании автоматизированного оборудования. Способ заключается в том, что перед выполнением операций по механической обработке поверхности ювелирных камней регистрируют сигналы акустической эмиссии из зоны обработки, а окончательную обработку камней ведут с учетом критерия, основанного на величинах измеренных сигналов акустической эмиссии (АЭ). Устройство для ориентации алмаза при обработке включает механизм ориентации алмаза и регистратор АЭ, подключенный к системе индикации и выполненный в виде пьезоэлемента, имеющего акустический контакт с алмазом. По первому варианту пьезоэлемент закреплен на механизме ориентации, а по второму варианту - на рабочих элементах корпуса стола. Изобретение позволяет сократить время и повысить точность ориентации алмаза при обработке, а также автоматизировать данный процесс.The invention relates to a technology for processing jewelry stones, can be used to create automated equipment. The method consists in the fact that before performing machining of the surface of jewelry stones, acoustic emission signals from the processing zone are recorded, and the final processing of stones is carried out taking into account a criterion based on the values of the measured acoustic emission signals (AE). The device for orienting diamond during processing includes a diamond orientation mechanism and an AE recorder connected to an indication system and made in the form of a piezoelectric element having acoustic contact with diamond. In the first embodiment, the piezoelectric element is fixed on the orientation mechanism, and in the second embodiment, on the working elements of the table case. EFFECT: invention reduces time and improves accuracy of diamond orientation during processing, as well as automates this process.
