18.10.3 Mirror wear lengths (SD42920 $SC_WEAR_SIGN_CUTPOS)
Activation
Wear length mirroring is activated by:
SD42920 $SC_WEAR_SIGN_CUTPOS <> 0 (TRUE) (Sign of wear for tools with cutting edge systems)
Function
In the case of tool types without a relevant cutting edge position, the wear length is not mirrored.
SD42930 $SC_WEAR_SIGN
Setting data not equal to zero:
Inverts the sign of all wear dimensions. This affects both the tool length and other variables such as tool radius,
rounding radius, etc.
Entering a positive wear dimension makes the tool "shorter" and "thinner".
Activation of modified setting data
When the setting data described above are modified, the tool components are not reevaluated until the next time
a tool edge is selected. If a tool is already active and the data of this tool are to be reevaluated, the tool must be
selected again.
Length of cutting edge Length 1 Length 2
1 --- ---
2 --- Inverted
3 Inverted Inverted
4 Inverted ---
5 --- ---
6 --- ---
7 --- Inverted
8 Inverted ---
9 --- ---
Note
The mirroring (sign inversion) in one or more components can cancel itself through a
simultaneous activation of the functions:
Tool length-mirroring (SD42900 <> 0)
And:
Tool length-mirroring (SD42920 <> 0)
