Guide for Face Grooving (Continued) Point (I) (Turning after Grooving) 1) Grooving Depth Over 0.5mm: For roughing (Refer to Fig.4) Before turning, pull the tool back about 0.1mm after grooving, instead of turning subsequent to grooving. (Failure to pull the tool back before traverse machining will result in an unbalanced load applied on only one side of the cutting edge.) Before turning, pull the tool back about 0.1mm after grooving. (Grooving Depth Over 0.5mm: At roughing) Fig.4 2) Grooving Depth under 0.5mm: For finishing (Refer to Fig.5) Turning subsequent to grooving is possible because shallow groove depths relate a small load on the cutting edge. (Retention time is not necessary.) Turning subsequent to grooving (Grooving Depth under 0.5mm: At finishing) Fig.5 Point (II) 1) When widening the groove width. (Ref. to Fig.6) Apply the “Step Turning. 2) The widened groove and side walls should be finished last. (For better chip control, ap over 0.5mm is recommended.) Trouble shooting > 5 Trouble Countermeasures Whitish trace remains at the groove bottom. (1) Increase the cutting speed for finishing process o (This can handle most of the cases. ) If the method is not successful, try (2) as follows. (2) Check the insert edge’s parallelness. Adjustment: Apply the insert edge to the workpiece face and adjust the toolholder within the angle of ±5'. (Fig.7) nly. -x 1 1 1 1 / Fig 1 7 Chips are entangled. (1) Install the toolholder in the reverse position. Adjust the coolant flow to the cutting edge. (2) When widening the groove, do not machine one deep groove. Instead, repeat shallow grooving and turning. Insert cracks when turning. Reverse the facing direction. Groove is not straight. Check the edge's parallelness. Decrease the feed rate. G107
