Activating a transformation with TRAFOON
In addition to the name of the transformation, the reference diameter can also be specified for
TRACYL and a setting as to whether the "Slot side offset" function is active is also possible:
TRAFOON (<transformation name>, <diameter>, <k>)
With k = 1, the slot side offset is carried out, see Activating a transformation (TRAFOON)
(Page 317).
Supplementary conditions
● There must be exactly one rotary axis (the polar axis), with its name in
$NT_ROT_AX_NAME[n,1].
● There can be 1 to 3 entries for linear axes in the system parameters
$NT_GEO_AX_NAME[n,i].
Coordinate systems for cylinder surface transformations
The workpiece coordinate system and the basic coordinate system are independent of the
world coordinate system in which the kinematic chains are defined.
● The Z axis is parallel to the polar axis (axis B - see above) and parallel to the longitudinal
axis, if it is defined.
● The geometry axes X, Y and Z are vertical to one another and form a perpendicular
coordinate system in the order 1st, 2nd and 3rd geometry axis.
● If the longitudinal axis ($NT_GEO_AX_NAME[n, 2]) exists, it must always be parallel to the
rotary axis ($NT_ROT_AX_NAME[n, 1]).
