Cutting edge position and cut direction
Turning tools are limited by their main and secondary cutting edges. The tool parameter "Cutting edge position"
is defined via the position of these two cutting edges relative to the coordinate axes. The ratios are displayed with
diagram in the following figure:
Figure 18-44 Cutting edge position and cut direction for turning tools
The values 1 to 4 characterize the cases in which both cutting edges lie in the same quadrant; the values 5 to 8
characterize the cases in which both cutting edges lie in neighboring quadrants or there is a coordinate axis
between the two cutting edges. The cutting edge position is stored in the tool parameter $TC_DP2.
A cut direction can be defined for each turning tool. It is stored in the tool parameter $TC_DP11. It has values
between 1 and 4, and it characterizes a positive or negative direction of the coordinate axes:
Two different cut directions can be assigned to each cutting edge position:
