Bit 0 = TRUE: Do not apply transformations to $TC_DP12 - $TC_DP14.
Bit 1 = TRUE: Do not apply transformations to $TC_SCPx3 - $TC_SCPx5.
Bit 2 = TRUE: Do not apply transformations to $TC_ECPx3 - $TC_ECPx5.
The bits not mentioned here are (currently) not assigned.

Description:
If this setting data is not equal to 0, the assignment of tool length components
(length, wear, base dimensions) to geometry axes is not changed when the machining
plane (G17 - G19) is changed.
The assignment of tool length components to geometry axes can be derived from the value
of the setting data according to the following tables.
The assignment of the tool orientation components is not affected by this setting
data. Setting data SD42945 $SC_TOOL_ORI_CONST_M and SD42947 $SC_TOOL_ORI_CONST_T may
have to be set accordingly.
A distinction is made between turning and grinding tools (tool types 400 to 599)
other tools (typically milling tools) in the assignment.
Representation of this information in tables assumes that geometry axes 1 to 3 are
called X, Y and Z. For assignment of an offset to an axis, not the axis identifier but
the axis sequence is relevant.
Assignment for turning tools and grinding tools (tool types 400 to 599):

* Any value which is not 0 and is not one of the six values listed, is treated as value
18.
For values that are the same but with a different sign, assignment of length 3 is
always the same, lengths 1 and 2 are reversed. Assignment for all tools which are
neither turning nor grinding tools (tool types < 400 or > 599):

For values that are the same but with a different sign, assignment of length 1 is
always the same, lengths 2 and 3 are reversed.
