Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Supplementary conditions
If the "Scratch" function is used in the
RESET
state, the following must be noted with respect
to the initial setting:
• The wear components are evaluated depending on the initial settings of the G-code
groups
TOWSTD
,
TOWMCS
and
TOWWCS
.
• If a value other than the initial setting is needed to ensure correct calculation, scratching
may be performed only in the STOP state.
Note
"Special handling of tool compensations" pays particular attention to tool compensations
with evaluation of sign for tool length with wear and temperature fluctuations.
The following are taken into account:
• Tool type
•
Transformations for tool components
•
Assignment of tool length components to geometry axes independently of tool type
2.8 Special handling of tool compensations
2.8.1 Relevant setting data
SD42900- 42960
Setting data SD42900 - SD42940 can be used to make the following settings with reference
to tool compensation:
•
Sign of the tool length
•
Sign of the wear
•
Behavior of the wear components when mirroring geometry axes
•
Behavior of the wear components when changing the machining plane via setting data
•
Allocation of the tool length components independent of actual tool type
•
Transformation of wear components into a suitable coordinate system for controlling the
effective tool length
