V
Variable land
Shape of the cutting edge with different width land on the periphery of the rake face of the insert.
Vibrations
Shaking movement of the tool and the workpiece due to bad cutting conditions.
W
Waviness
Wave shape on the vertical wall surface produced by end milling.
Wetting angle
When a liquid droplet is placed on the surface of another material, the wetting angle refers to the tangential angle between the base and the surface of the droplet. The larger the angle is the lower is the wettability. This basically refers to the ability to adhere with other materials.
Width of wiper edge
The width of the wiper edge.
Wiper edge normal clearance
The clearance angle below the wiper edge.
Y
Young’s modulus
Tensile modulus on normal stress and normal strain.
Z
Zero cut (Spring cut)
Zero cut (Spring cut) is an operation to recut a component at a zero depth of cut.
V-T diagrams
A graph showing a relationship between cutting speed and tool life.
Wiper Insert
An insert to cut a machined surface again and finish it level.
Work Hardening
When cold-working (rolling, drawing, forging) metal, its hardness and tensile strength will increase, and metal will not extend and will become brittle.
