8.4.2 Turntable Off-Centering (DAT3)
Offsets related to off-centering of the turntable (DAT3) are no longer processed as
such when the RTCP function is enabled. Since the position of the turntable rotary
axis is known, this correction is automatically included in the RTCP function.
8.4.3 Tool Length Correction
When the tool is carried by a twist axis, the length correction is no longer processed
as an offset on the tool axis, but is included in the twist movements with the orientation
declared in the IJK vector programmed (see «Description of Twist Heads»).
Declaration and dimension assigned to the tool correction
The tool correction must be declared before enabling the RTCP function. The value
assigned to the correction is stored when RTCP is enabled and saved as long as
RTCP remains enabled. Any changes in the correction are ignored until RTCP is
inhibited (G26-) then reenabled.
8.4.4 Tool Wear Offset
Tool length wear offsets less than 100 µ (0.1 mm) are immediately taken into account
and included (like the length correction) in the twist movements with the orientation
declared in the vector IJK programmed (see «Description of Twist Heads»).
8.4.5 3D Tool Correction (G29)
3- or 5-axis tool correction in G29
3-axis tool correction
When the RTCP function is used with 3-axis tool correction (no tool orientation vector
IJK in the G29 blocks), the system processes only the case of the spherical tool.
5-axis tool correction
When the RTCP function is used with 5-axis tool correction (presence of tool
orientation vector IJK in the G29 blocks), the system is able to process the case of
the toroid tool.
Display of the tool centre in G29.
During interpolation, the tool centre dimensions can be displayed on the «AXIS»
current position coordinate page with respect to the programme origin (OP).
