Special points to be noted
If TOWMCS or TOWWCS is active, the following setting data does not affect the non-transformed wear components:
SD42920 $SC_WEAR_SIGN_CUTPOS (Sign of wear for tools with cutting edge systems)
The following setting data also does not affect the non-transformed wear components in case of TOWWCS:
SD42910 $SC_MIRROR_TOOL_WEAR (Sign change tool wear when mirroring)
In this case, a possibly active mirroring is already contained in the frame, which is referred to for evaluating the
wear components.
On a plane change, the assignment between the nontransformed wear components and the geometry axes is
retained, i.e., these are not interchanged as with other length components. The assignment of components
depends on the active plane for tool selection.
Example
Let's assume a milling tool is used where only the wear value $TC_DP12 assigned to length L1 is not equal to
zero.
If G17 is active, this length is effective in the direction of the Z axis.
This measure always acts in the Z-direction also upon a plane change after the tool selection, when TOWMCS or
TOWWCS are active and the bit 1 is set in the setting data:
SD42935 $SC_WEAR_TRANSFORM (transformations for tool components)
If, for example, G18 is active on tool selection, the component is always effective in the Y direction instead.
