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 fi t the particular situation. Recommended feed range is 0,08–0,3 mm/rev.

p ggpig depends on the material being cut and the width of the tool.		Groove Limits
