Токарные канавочные резцы Mitsubishi для наружного и внутреннего точения GROOVING _ MACHINING RECOMMENDATIONS I Notes on multi-functional machining (BM breaker) Copying APMX IWith the BM breaker insert, 3 dimensional copying is possible. Set the depth of cut (APMX) to 40% less than the insert width. Roughing L J lUse plunging and cross-feed machining. When machining the corner, vibration is likely to occur. To avoid this, reduce the feed by 50%. Finishing f) I APMX 2 Carry out finishing in one process. For the depth of cut (APMX 2) when back turning, refer to the table on the right.

If necessary, stop the feed prior to reaching the centre of the workpiece to prevent it falling under its own weight. Revolution aa Distance from the cutting edge to the workpiece centre 0.5xD When using constant cutting speed during a cutting off cycle, it is recommended to limit the spindle speed to 80% of maximum to ensure stability. To prevent the workpiece from being expelled, lower the spindle speed before finishing the grooving operation. Insert When there is a centre stub on solid bar work or bun's are formed on pipe material, it is possible to decrease them by using a handed insert. With a handed insert, machining tends to be less stable when compared to using a neutral insert. Pay special attention to avoid fracturing of the cutting edge and decrease the feed when necessary.
