TopGroove™ Machining Guidelines Machining Guidelines for Chip Control • Grooving When the proper cutter diameter is not available, proper cutter positioning will provide positive results. • Centre height of insert should be positioned at the centre of the workpiece or up to 0,13mm above. • Dwell time in the bottom of the groove (more than three revolutions) is not recommended. • Chip control is feed-rate related and should be adjusted to fit the particular situation. Recommended feed range is 0,08–0,3 mm/rev. Machining Guidelines for Chip Control • Turning/Profiling Maximum depth of cut for side cutting (turning/profiling) Groove Limits depends on the material being cut and the width of the tool. • 0,79–1,6mm wide insert maximum internal minimumgroove depthbore diameter can cut up to 0,6mm deep. insert • 1,7–3,3mm wide insert catalogue number mm mm can cut up to 1mm deep. NG-1094L 1,91 20,32 • 3,5–4,8mm wide insert — 1,02 11,18 can cut up to 2mm deep. NG-2031R/L 1,27 18,54 • 5–6,35mm wide insert can cut up to 3mm deep.

To avoid insert chipping and to achieve groove wall NG-3142R/L — — perpendicularity, follow the tool path outlined. 4.

The same internal grooving depth limits are a function of bar clearance versus bore diameters. E86 widia.com
