The invention discloses a vibration damping tool automatically compensating machining method for precision deep hole cutting and a case. The machining allowance reserved for machining of a precision deep hole is 3a, three feeds are performed until the final size is machined, comprise primary feed, secondary feed and tertiary feed, and comprise the following steps: S1, primary feed machining is performed, and the feed amount of primary feed is a1; S2, the size of the precision deep hole is measured, the remaining machining allowance A is calculated, secondary feed machining is performed, and the feed amount of secondary feed is a2, wherein a2 = A - a1; S3, the size of the precision deep hole is measured again, the final machining allowance B is calculated, tertiary feed is performed, and the feed amount a3 of the tertiary feed is B. According to the vibration damping tool automatically compensating machining method for precision deep hole cutting, the tool yielding error is automatically compensated and eliminated on the basis of yielding rules by three-feed machining, and machining precision and surface quality of the precision deep hole are ensured.
本发明公开了一种减振刀具自动补偿切削精密深孔的加工方法和机匣,精密深孔处加工预留的加工余量为3a,分三次进刀加工至最终尺寸,三次进刀加工包括第一次进刀、第二次进刀和第三次进刀;三次进刀加工包括以下步骤:S1:进行第一次进刀加工,第一次进刀的进刀量a1为S2:测量精密深孔的孔径尺寸,计算剩余加工余量A,进行第二次进刀加工,第二次进刀的进刀量a2为a2=A-a1;S3:再测量精密深孔的孔径尺寸,计算最终加工余量B,进行第三次进刀加工,第三次进刀的进刀量a3为B。本发明的减振刀具自动补偿切削精密深孔的加工方法,通过三次进刀加工,利用让刀规律自动补偿消除让刀误差,提高切削稳定性,保证精密深孔的加工精度和表面质量。
