Transformations
6.8 Kinematic transformation
Syntax
TRACYL(d) or TRACYL(d, n) or
for transformation type 514
TRACYL(d, n, groove side offset)
TRAFOOF
Rotary axis
The rotary axis cannot be programmed as it is occupied by a geometry axis and thus cannot
be programmed directly as channel axis.
Significance
TRACYL(d)
TRACYL (d, n)
D
n
Slot side compensation
TRAFOOF
OFFN
Note
An active TRACYL transformation is likewise deactivated if one of the other transformations
is activated in the relevant channel (e.g., TRANSMIT, TRAANG, TRAORI).
414
Activates the first TRACYL function specified in the channel
machine data. d is the parameter for the working diameter.
Activates the n-th TRACYL function specified in the channel
machine data. The maximum for n is 2, TRACYL(d,1)
corresponds to TRACYL(d).
Value for the working diameter. The working diameter is
double the distance between the tool tip and the turning
center. This diameter must always be specified and be larger
than 1.
Optional 2nd parameter for the TRACYL data block 1
(preselected) or 2.
Optional 3rd parameter whose value for TRACYL is
preselected using the mode for machine data.
Value range:
0: Transformation type 514 without groove wall offset as
previous
1: Transformation type 514 with groove wall offset
Transformation OFF (BCS and MCS are once again identical).
Offset contour normal: Distance of the groove side from the
programmed reference contour.
