Detailed description
2.6 Generic 5-axis transformation and variants
Transformation types
Both variants of generic 3- or 4-axis transformation are described by the following
transformation types:
• 3- or 4-axis transformation with rotatable tool
• 3- or 4-axis transformation with rotatable workpiece
In conventional 3-axis or 4-axis transformations, the transformation type also defined the
basic tool orientation in addition to the position of the rotary axis, which could then no longer
be influenced.
Effects on orientations
Generic 3-axis or 4-axis transformation has the following effect on the various orientations:
The resulting tool orientation is defined according to the hierarchy specified for generic 5-
axis transformation.
Priority:
• high: programmed orientation,
• medium: tool orientation and
• low: basic orientation
Allowance is made, in particular, for the following orientations:
• A programmed tool orientation
• A basic tool orientation, modified by orientable toolholders.
Note
Further information on programmable tool orientation and on basic tool orientation can be
