Internal Rough tool

Definition

A	The width of the tool holder.
B	The distance between the tool tip point and the side of the tool holder. Note that a negative value will cause the holder side to move outwards from the tool tip point.
C	The height of the tool tip carrier.
D	The height of the tool (not including the turret); must be greater than C.
D1, D2	The lengths of the two cutting edges of the tool tip. These lengths define the maximum step down size during turning.
a°	The tool tip angle; must be between 0 and 180 degrees.
b°	The angle between the tool tip edge and a perpendicular passing through the tool tip point. The sum of a° and b° must be smaller than 90.
E	The position of the left side of the turret with reference to the tool tip point. A negative value means that the left side of the turret will be to the left of the tool tip point.
F	The width of the turret.
Ra	The tool nose radius.
Thickness	The thickness of the tool.
