Mirroring of tool lengths (SD 42900: MIRROR_TOOL_LENGTH)
Activation
Tool length mirroring is activated by:
SD42900 $SC_MIRROR_TOOL_LENGTH <> 0 (TRUE)
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.
2-116
(mirroring of tool length components and components of the tool base dimension)
(mirroring of wear values of tool length components)
(sign evaluation of the wear components)
(inverts the sign of the wear dimensions)
(allocation of the tool length components to the geometry axes)
(allocation of the tool length components independent of tool type)
(transformation of wear values)
(tool length offsets)
