SETTING AND DISPLAY OF DATA
2. TOOL DATA AND TOOLING
“AS”, “ZS” and “XS” indicate the setting direction and setting
position of the cutting tool defined by the previous method.
Determine the “AS” value and sign by turning the cutting tool
figure in an optional direction as it is.
The ”AS” angle is minus in the clockwise direction.
(2)When the turret is set at the front side.
In this case, select or as the drawing format in order to clearly
identify positive and negative value of tool data.
(a) Tool figure
Input dimensions, referring to the following figures, irrespective of
whether the outer diameter cutting or inner diameter cutting is
done. Assume that a tool was placed on paper with its mounting
face to an NC lathe turned upward, regardless of the front face or
rear face of the cutting tool.
The “AC” plus direction is counterclockwise around the major
cutting edge as the center, while the “AN” plus direction is
clockwise around the major cutting edge as the center. (The bold
line in the figure shows the major cutting edge.)
