Activating a transformation (TRAFOON)

A transformation defined with kinematic chains is activated with the predefined TRAFOON
procedure. The call must be alone in a block.
Note
Alternatively, a transformation defined with kinematic chains can also be activated via
conventional NC commands, such as TRAORI or TRANSMIT. For this purpose, an appropriate
value, not equal to zero, must be entered in the $NT_TRAFO_INDEX system variable.
For further information on $NT_TRAFO_INDEX see "System Variables List Manual".
Syntax
TRAFOON(<Trafoname>,<Diameter>,<k>)
Meaning
TRAFOON:
<Trafoname>:
<Diameter>:
<k>:
Example
Program code
TRAFOON["Trans_1"]

Procedure for activating a transformation defined with kinematic chains
Name of the transformation data set
Data type: STRING
Range of val‐ All names of transformation data sets defined via $NK_NAME
ues:
Note:
The name of the transformation data set must be unique. It must only occur once
in $NT_NAME.
Reference or working diameter (TRACYL only)
Data type: REAL
The value must be > 1.
Defines the use of the groove side offset (TRACYL only).
Data type: BOOL
Value: FALSE
TRUE
Corresponds to the TRACYL transformation type 514 (groove side offset can be
programmed). If <k> is not specified, the parameterized setting of bit 10 in
$NT_CNTRL[<n>] applies.
Comment
Activates the transformation with the name Trans_1.
Without groove side offset
With groove side offset
