6.5 Chained transformations
Extended Functions
388 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
● Assignment of geometry axes to channel axes
– general situation (no transformation active)
● Assignment of channel axes to machine axis numbers
● Identification of spindle, rotation, modulo for axes
● Allocation of machine axis names.
● Transformation-specific settings (for individual transformations and for chained
transformations)
– Transformation type
– axes going into transformation
– Assignment of geometry axes to channel axes during active transformation
– depending on transformation, rotational position of the co-ordinate system, tool zero
point in relation to the original co-ordinate system, angle of the inclined axis, etc.
Number of transformations
Up to ten transformation data blocks can be defined for each channel in the system. The
machine data names of these transformations begin with $MC_TRAFO .. and end with ... _n,
where n stands for a number between 1 and 10.
Number of chained transformations
Within the maximum of 10 transformations of a channel, a maximum of two chained
transformations may be defined.
Transformation sequence
When configuring the machine data, the data concerning the single transformations (that
may also become part of chained transformations) must be specified before the data
concerning the chained transformations.
Chaining sequence
With chained transformations the second transformation must be "inclined axis" (TRAANG).
Chaining direction
The BCS is the input for the first of the transformations to be chained; the MCS is the output
for the second one.
Supplementary conditions
The supplementary conditions and special cases indicated in the individual transformation
descriptions are also applicable for use in chained transformations.
