Turning and external grooving Turning with a parting and grooving insert. When side turning, use a depth of cut (a p) larger than the insert corner radii; Wiper effect − feed rate per depth of cut (f n/a p) must be relatively high to ensure a slight deflection of tool and insert. This provides a clearance between the cutting edge and machined surface

Y-axis parting is a completely new way of parting-off. In conventional parting off, most of the cutting force is generated by the cutting speed, the rest by the cutting feed. The resulting force is directed approximately 30 degrees into the tool. Thereby, the parting-off blades are loaded in their second weakest direction.
