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.
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.
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.
