Transformations
7.8 Kinematic transformation
Job planning
7-56 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
For cylinder peripheral curve transformation with groove side compensation, the axis used
for compensation should be positioned at zero (y=0), so that the groove centric to the
programmed groove center line is finished.
Axis utilization
The following axes cannot be used as a positioning axis or a reciprocating axis:
• The geometry axis in the peripheral direction of the cylinder peripheral surface (Y axis)
• The additional linear axis for groove side compensation (Z axis).
Programming
TRACYL(d) or TRACYL(d, n) or
for transformation type 514
TRACYL(d, n, groove side offset)
or
TRAFOOF
Rotary axis
The rotary axis cannot be programmed because it is occupied by a geometry axis and
cannot thus be programmed directly as a channel axis.
Parameters
TRACYL(d) Activates the first TRACYL function specified in the
channel machine data. d is the parameter for the working
diameter.
TRACYL (d, n) 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).
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.
n Optional 2nd parameter for the TRACYL data block 1
(preselected) or 2.
Slot side compensation 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
TRAFOOF Transformation OFF (BCS and MCS are once again identical).
OFFN Offset contour normal: Distance of the groove side from the
programmed reference contour.
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).
