Inclusion of wear values in calculation
The setting data SD42935 $SC_WEAR_TRANSFORM defines which of the three wear
components:
● Wear
● Total offsets fine
● Total offsets coarse
should be subject to a rotation using adapter transformation or a tool holder that can be
orientated if one of the following G codes is active:
●
TOWSTD Default setting
For offsets in the tool length
●
TOWMCS wear values
In the machine coordinate system (MCS)
●
TOWWCS wear values
In the workpiece coordinate system (WCS)
●
TOWBCS wear values (BCS)
In the basic coordinate system
●
TOWTCS wear values in the tool coordinate system at the tool holder reference (T tool
holder reference)
●
TOWKCS Wear values in the coordinate system of the tool head for kinematic transformation
Note
Evaluation of individual wear components (assignment to geometry axes, sign evaluation)
is influenced by:
• The active plane
• The adapter transformation
• Following setting data:
– SD42910 $SC_MIRROW_TOOL_WEAR
– SD42920 $SC_WEAR_SIGN_CUTPOS
– SD42930 $SC_WEAR_SIGN
– SD42940 $SC_TOOL_LENGTH_CONST
– SD42950 $SC_TOOL_LENGTH_TYPE
