transformation machine

Two-axis swivel head with
tool which rotates around
itself and single-axis rotary
table
When calling "generic three-, four-, and five/six-axis transformation", the basic orientation of
the tool can also be transferred. The restrictions in respect of the directions of the rotary
axes no longer apply. If the rotary axes are not exactly vertical to one another or existing
rotary axes are not exactly parallel with the linear axes, "generic five-/six-axis transformation"
can provide better results in respect of tool orientation.
Kinematic transformations TRANSMIT, TRACYL and TRAANG
For milling on turning machines or an axis that can be set for inclined infeed during grinding,
the following axis arrangements apply by default in accordance with the transformation
declared:
TRANSMIT
Face machining in the
turning clamp
TRACYL
Machining of grooves with
any path on cylindrical
bodies
TRAANG
Machining with an oblique
infeed axis

6.1 General programming of transformation types
Programming of orientation transformation
Programming of orientation transformation. Kinematics with
three linear axes and three orthogonal rotary axes.
The rotary axes are parallel to two of the three linear axes. The
first rotary axis is moved by two Cartesian linear axes. It rotates
the third linear axis with the tool. The second rotary axis rotates
the workpiece. The basic tool orientation can also be
programmed with additional rotation of the tool around itself with
the THETA rotary angle.
