Description

Изобретение относитс  К области металлообработки и может  айти применваие во всех отрасл х прамышлениости при 1вьгборе режимов |работы (саиральными оверлами.The invention relates to the field of metalworking and can be applied in all fields of industry during the first choice of work modes (with satellite overlays.

Известен слособ Э:кспер1име;нталь«ого определени  оптимального режима Сверлени  ио стошадоти дл  сверл малых диаметров (до 1 ) при работе без колдуктора.The following method is known: xper1im; ntal “determination of the optimal mode of drilling and drilling for small diameters (up to 1) when working without a coil.

По этому способу при определбн.ии оптимальной величины одного параметра, например скорости резани , другие параметры процесса сверлени  юохран  ют посто иными.According to this method, when determining the optimal value of one parameter, for example, cutting speed, other parameters of the drilling process keep constant.

В ходе СТОЙКОСТ1НЫХ экспериментов при различных фи-ксиро&аиных значени х скорости резааи  s соответств ии с при.н тым критерием затупле н  сверла определ ют фактическую его стойкость и после графоа1налитической обработки у1Ста1наВЛИвают оптимальную велич1ину скорости резаии .In the course of STABILITY experiments with various phi-xi & ai cut values of the cutting speed s, the actual strength of the bit is determined, and after the graphical processing of the i1St1 1 1, the optimal value of the cutting speed is affected.

Предлагаемый Способ отличаетс  от изве .стного тем, что параметрьЕ устаиавливают по велдачиие наименьшего начального смещени  вершины сверла при сверлении.The proposed method differs from the well-known fact in that the parameters are set by the minimum initial displacement of the drill tip when drilling.

Такой 1Способ ускор ет испытани  при сверлении определенного материала с неизменным качеством ло верхнасти (сверла1ми од1И1накозых размеров.Such a method accelerates testing when drilling a certain material with a constant surface quality (drill bits of one size).

Предлагаемый способ осуществл ют следующиМ образом. В ходе опытов Л131мен ют лищь одии пара.метр, иаиример скорость резаии , а другие пар а.метры процесса сверлени  сохран ют посто нными. При различных фИКоированных значени х скорости резани  определ ют величину начального смещени  вершииы сверла, став  ио 5-10 опытов в каждой точке. После соответствующей графоаналитической обработк.и экспср1Н ментальных данных определ ют величаиу скорости резани , соответствующую минимальному начальпюму смещению. Эта величина и  вл етс  скоростью сверлени , оптимальной по стой.кости . Аналогично поступают и при определении подачв.The proposed method is carried out as follows. In the course of the experiments, L131 changes the parameters of the meter, the measuring process, and the other pairs and meters of the drilling process are kept constant. At various fixed values of the cutting speed, the magnitude of the initial displacement of the drill tip is determined, becoming about 5-10 experiments at each point. After the corresponding graphoanalytical processing and expr1H of the mental data, determine the magnitude of the cutting speed corresponding to the minimum initial displacement. This value is the drilling speed optimal in stability. Similarly, they do in determining the pitches.
