7.3.3 Activation of TRACYL
TRACYL
After the settings described above have been made, the TRACYL function can be activated:
TRACYL(d)
or
TRACYL(d,t) TRACYL(reference diameter, Tracyl data block)
TRACYL(d) is used to activate the first declared TRACYL function. TRACYL(d,t) activates the
t-th declared TRACYL function – t may not be greater than 2. The value d stands for the
current diameter of the cylinder to be machined.
Between activation of the function and deactivation as described below, the traversing
movements for the axes of the cylinder coordinate system can be programmed.
Transformation type 514 with groove side offset
An additional call parameter is used for transformation type 514; this is the third parameter
with which TRACYL transformation with groove side offset can be selected:
TRACYL(reference diameter, Tracyl data block, groove side offset).
● Reference diameter: Obligatory parameter (must always be defined)
● Tracyl data block: Optional parameter, preset value is 1
● Groove side offset: Optional parameter, preset value corresponds to value specified in
7.3.4 Deactivation of the TRACYL function
TRAFOOF
The keyword TRAFOOF deactivates an active transformation. When the transformation is
deactivated, the base coordinate system is again identical to the machine coordinate system.
An active TRACYL transformation is likewise deactivated if one of the other transformations is
activated in the relevant channel (e.g. TRANSMIT, TRAANG, TRAORI).
