2.8.3 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
Length of cutting edge Length 1 Length 2
1 --- ---
2 --- Inverted
3 Inverted Inverted
4 Inverted ---
5 --- ---
6 --- ---
7 --- Inverted
8 Inverted ---
9 --- ---
In the case of tool types without a relevant cutting edge position, the wear length is not
mirrored.
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)
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".
