Description
Изобретение относитс к обработке металлов резанием и может быть использовано при обработке жаропрочных сталей и сплавов.The invention relates to the processing of metals by cutting and can be used in the processing of heat-resistant steels and alloys.
Целью изобретени вл етс повышение производительности обработки и качества обрабатываемой поверхности деталей.An object of the invention is to increase the processing productivity and the quality of the workpiece surface.
Дл этого повышают пластичность материала при одновременном увеличении стойкости инструмента в услови х высоких скоростей резани .To this end, the ductility of the material is increased while the tool life is increased under conditions of high cutting speeds.
Способ осуществл ют следующим образом .The method is carried out as follows.
Детали из жаропрочных сталей или сплавов обрабатывают резанием с применением инструментального материала, теплостойкость которого не ниже (6U+300) например материала на основе кубического нитрида бора (КНБ).Parts of heat-resistant steels or alloys are processed by cutting using tool material, the heat resistance of which is not lower than (6U + 300), for example, material based on cubic boron nitride (CBN).
Если дл данного жаропрочного сплава впп не известна, ее определ ют в результатеIf the runway is not known for a given heat-resistant alloy, it is determined as a result
кратковременных стандартных испытаний. Определ ют температуру на различных скорост х резани и стро т график зависимости в - f(V), из которого определ ютshort-term standard tests. The temperature at various cutting speeds is determined and a plot of in - f (V) is constructed, from which the
скорость резани V. соответствующую ( $1л+30°). Дл VK определ ют пор док величины скорости деформации с. (Дл жароп- рочностных сталей и сплавов при V-300-600. м/мин к 1015 ). Корректируют значени впп и соответственно VK с учетом ё . Если не учитывать вли ние е, то вV. cutting speed appropriate ($ 1L + 30 °). For VK, an order of magnitude of strain rate c is determined. (For heat-resistant steels and alloys at V-300-600. M / min to 1015). The values of runway and VK are adjusted accordingly taking into account g. If we ignore the effect of e, then in
р де случаев, когда впп зависит от Ј , мож- но не попасть в диапазон скоростей резани , где достигаетс положительный эффект.In some cases when runway depends on Ј, one may not fall into the range of cutting speeds where a positive effect is achieved.
