Description
(54) СПОСОБ КОНТРОЛЯ ИЗНОСА ИНСТРУМЕНТА ПРИ ТОКАРНОЙ ОБРАБОТКЕ(54) METHOD OF CONTROL OF WEARING TOOL DURING TURNING
1one
Изобретение относитс к области металлообработки на токарных станках и предназначено дл определени величины износа режущего инструмента, а также дл управлени процессом резани и контрол .The invention relates to the field of metalworking on lathes and is intended to determine the amount of wear of the cutting tool, as well as to control the cutting process and control.
Известны способы контрол износа инструмента при токарной обработке, при которых в теле инструмента располагают датчики взаимно перпендикул рно друг другу в трех плоскост х, две из которых перпендикул рны оси вращени детали, регистрируют амплитуды действующих сил по отношению к третьей, выбранной в качестве эталонной, и определ ют разность между этими измерени ми 1.Methods are known for monitoring tool wear during turning, in which sensors are placed in the tool body mutually perpendicular to each other in three planes, two of which are perpendicular to the axis of rotation of the part, register the amplitudes of the acting forces with respect to the third, selected as the reference, and determine the difference between these measurements 1.
Недостатком таких способов вл етс отсутствие контрол износа инструмента в процессе обработки.The disadvantage of such methods is the lack of control of tool wear during processing.
Целью изобретени вл етс повышение точности контрол износа режущего инструмента .The aim of the invention is to improve the accuracy of control of wear of the cutting tool.
Поставленна цель достигаетс тем, что по предложенному способу формируют временной интервал измерени разности на первом временном интервале, сравнивают со значени ми на последующих временных интервалах и по величине отклонени значени разностей определ ют степень износа инструмента.This goal is achieved by the fact that according to the proposed method, the time interval for measuring the difference in the first time interval is formed, compared with the values for the subsequent time intervals and the degree of tool wear is determined from the deviation of the difference value.
На чертеже показана структурна схема устройства, реализующего предлагаемый способ.The drawing shows a block diagram of the device that implements the proposed method.
При токарной обработке датчики 1-3 устанавливают в теле инструмента взаимно перпендикул рно и измер ют силы / , Ри и Яг - соответственно.During turning, the sensors 1-3 are installed in the tool body mutually perpendicular and the forces I, Pu and Yag are measured, respectively.
В качестве датчиков могут быть использованы акселерометры или другие датчики. Accelerometers or other sensors can be used as sensors.
10 позвол ющие измерить внутренние напр жени , возникающие в резце под действием сил РХ., PIJ и .10 which allow one to measure the internal stresses arising in the tool under the action of forces PX, PIJ and.
Сигналы поступают с датчиков в блок измерени сдвига фаз 4, куда поступают curis налы с блока формировани временного интервала 5. Сигналы с блока 5 поступают на блок пам ти 6 и блок сравнени 7, откуда сигнал идет на блок измерени разности значений 8.The signals come from the sensors to the phase shift measurement unit 4, where curys flow from the time interval shaping unit 5. The signals from block 5 go to memory block 6 and comparison unit 7, from where the signal goes to the value difference measurement unit 8.
В процессе резани датчики I - 3 вос20 принимают действие сил резаш . а тгккже как резец в процессе резани совершаег колебани в результате действи этих сил, то на выходе датчиков сигнал, хг.рактернзующий действие сил, имеет колеб; тельный x;iDuring the cutting process, I-3 sensors 20 take action of the cutting forces. and, as a cutter, in the process of cutting, it oscillates as a result of the action of these forces, then at the output of the sensors the signal, xy. The drawing effect of the forces, has a vibration; solid x; i
