17 Guide for External Grooving 1) Traversing After Grooving 1. Grooving Depths Over 0.mm : At Roughing (see Fig.1) Before traversing, pull the tool back about 0.1mm after grooving, instead of traversing subsequent to grooving. (Failure to pull the tool back before traverse cutting will result in an unbalanced load applied on only one side of the cutting edge.) Fig.1 Before traversing, pull the tool back about 0.1mm after grooving. (Grooving depth over 0.mm : At roughing) 2. Grooving Depths Under 0.mm : At Finishing (see Fig.2) Traversing subsequent to grooving is possible because shallow groove depths relate a small load on the cutting edge. (Dwell-motion is not necessary) Fig.2 Traversing subsequent to grooving. (Grooving depth under 0.mm : At Finishing) 2) 1. hen widening the groove width, apply the "Step Turning" as shown in Fig. Fig. 2. The widened groove and side walls should be finished last. (For better chip control, D.O.C. over 0.mm is recommended.) Note: If the workpiece is not supported at the center, reduce the feed rate when grooving towards center 0.1 mm 1
