Abstract
Изобретение относитс к обработке материалов резанием и может быть использовано при точении деталей из труднообрабатываемых высоколегированных и жаропрочных сталей. Целью изобретени вл етс повышение стойкости режущего инструмента. В процессе обработки заготовки 1 режущим инструментом 2 на ее поверхность дополнительно воздействуют лазерным излучением одновременно в двух зонах, одна из которых расположена на линии отделени стружки, а друга - на поверхности резани на рассто нии, составл ющем 0,3 ширины срезаемого сло , но не менее половины диаметра сфокусированного луча лазера от линии пересечени поверхности резани с обрабатываемой поверхностью. 1 ил.The invention relates to the processing of materials by cutting and can be used in turning parts of hard-machined high-alloyed and heat-resistant steels. The aim of the invention is to increase the durability of the cutting tool. During the processing of the workpiece 1 by the cutting tool 2, its surface is additionally affected by laser radiation simultaneously in two zones, one of which is located on the chip separation line and the other on the cutting surface at a distance of 0.3 of the cutting layer width, but not less than half the diameter of the focused laser beam from the line of intersection of the cutting surface with the treated surface. 1 il.
Description
Изобретение относится к обработке материалов резанием и может быть использовано при точении деталей из труднообрабатываемых высоколегированных и жаропрочных сталей.The invention relates to the processing of materials by cutting and can be used for turning parts from hard to work high alloy and heat resistant steels.
Целью изобретения является повышение стойкости режущего инструмента и производительности обработки.The aim of the invention is to increase the durability of the cutting tool and processing performance.
На чертеже представлена схема обработки по предложенному способу.The drawing shows a processing scheme for the proposed method.
Способ лазерно-механической обработки осуществляется следующим образом.The method of laser-mechanical processing is as follows.
В процессе обработки вращающейся заготовки 1 режущим инструментом 2 поверхность заготовки дополнительно нагревают одновременным воздействием в двух локальных зонах лазерным излучением, устанавливая одну из зон 3 нагрева на линии отделения стружки 4, а другую зону 5 — на поверхности резания на расстоянии, составляющем 0,3 ширины срезаемого слоя, но не менее половины диаметра сфокусированного луча лазера, от линии пересечения поверхности резания с обрабатываемой поверхностью, что способствует устранению нежелательной топографии износа режущего инструмента, характеризуемого образованием риски износа на границе контакта главной задней поверхности с обрабатываемым материалом и передней поверхности инструмента со сходящей стружкой, а также вызывает появление на участке срезаемого слоя внутренних напряжений, способствующих отклонению стружки на 5—7° в сторону обрабатываемой поверхности, что улучшает условия ее отвода из зоны обработки.In the process of processing a rotating workpiece 1 with a cutting tool 2, the surface of the workpiece is additionally heated by simultaneous exposure to laser radiation in two local zones, setting one of the heating zones 3 on the chip separation line 4, and the other zone 5 on the cutting surface at a distance of 0.3 width the cut-off layer, but not less than half the diameter of the focused laser beam, from the line of intersection of the cutting surface with the surface to be treated, which helps to eliminate unwanted wear wear topography cutting tool, characterized by the formation of wear risks at the interface between the main back surface with the material being processed and the front surface of the tool with descending chips, and also causes internal stresses to appear on the section of the cut layer, contributing to a 5–7 ° deflection of the chips towards the surface to be treated, which improves conditions for its removal from the processing zone.
