Guide for face grooving

1. Toolholder selection Check the range of applicable "external diameter of the groove" as well as the groove width 図2 and depth. 2. Cutting conditions (Feed rate: f) When machining on steel, set the feed rate (f) so that chips are created in a helical form in cut-off. f 3. How to widen the groove (plunge milling and turning) Start machining from the outside and then proceed to the inside. Chip control will be better in this way. Plunge milling (Grooving + side grooving) Turning 図2 GG 図3 図3

4. Guide for turning 図2 A. When the cutting amount (ap) is over 0.5 mm 1. Perform plunge milling. 2. Return the cutting by 0.1 mm. Failure to pull the tool back before traverse machining will result in an unbalanced load applied on only one side 図3 of the cutting edge. 3. Perform turning (Ref. to fig. 1)

3 When widening the face groove width(Ref. to fig. 2). Apply the “step turning”. Then perform finishing.

Fig. 2 図3 B. When the cutting amount (ap) is under 0.5 mm 1. Perform Plunge milling. 2. Perform turning. Machining without interruption is possible. (Ref. to fig. 3) 1
