Example:
The same applies in the event that the resulting tool length is modified due to a change in the mirroring status of
an axis. The tool must be selected again after the mirror command, in order to activate the modified tool-length
components.
18.10.4 Tool length and plane change (SD42940 $SC_TOOL_LENGTH_CONST)
Plane change
The assignment of tool length components (length, wear and tool base dimension) to geometry axes does not
change when the machining plane is changed (G17–G19).
Assignment of tools
The assignment of tool length components to geometry axes for turning and grinding tools (tool types 400 to 599)
is generated from the value of the following setting data in accordance with the following table:
SD42940 $SC_TOOL_LENGTH_CONST (change of tool length components on change of planes).
N10 $SC_WEAR_SIGN = 0 ; No sign inversion of the wear values
N20 $TC_DP1[1,1] = 120 ; End mill
N30 $TC_DP6[1,1] = 100 ; Tool radius 100 mm
N40 $TC_DP15[1,1] = 1 ; Wear dimension of tool radius 1 mm, resulting
tool radius 101 mm

N200 $SC_WEAR_SIGN = 1 ; Sign inversion for all wear values; the new
radius of 99 mm is activated on a new
selection (D1). Without D1, the radius would
continue to be 101 mm.
