18.10.2
Mirror tool lengths (SD42900 $SC_MIRROR_TOOL_LENGTH)
Activation
Tool length mirroring is activated via the setting data:
SD42900 $SC_MIRROR_TOOL_LENGTH <> 0 (TRUE) (Sign change tool length when mirroring)
Function
The following components are mirrored by inverting the sign:
• Tool lengths: $TC_DP3, $TC_DP4, $TC_DP5
• Tool base dimensions: $TC_DP21, $TC_DP22, $TC_DP23
Mirroring is performed for all tool base dimensions whose associated axes are mirrored. Wear values are not
mirrored.
Mirror wear values
The following setting data should be set in order to mirror the wear values:
SD42910 $SC_MIRROR_TOOL_WEAR <> 0 (Sign change tool wear when mirroring)
Inverting the sign mirrors the wear values of the tool length components whose associated axes are mirrored.
