Detailed description
Note
The transformations described below require that individual names are assigned to machine
axes, channels and geometry axes when the transformation is active. Compare macchine
data:
MD10000 $MN_AXCONF_MACHAX_NAME_TAB (machine axis name)
MD20080 $MC_AXCONF_CHANAX_NAME_TAB (name of the channel axis in the channel)
MD20060 $MC_AXCONF_GEOAX_NAME_TAB (name of the geometry axis in the channel)
Besides this no unambiguous assignments are present.
2.1 5-axis transformation
2.1.1 Kinematic transformation
Task of orientation transformation
The task of orientation transformation is to compensate movements of the tool nose, which
result from changes in orientation, by means of appropriate compensating movements of the
geometry axes. The orientation movement is therefore decoupled from the movement on the
workpiece contour. Various machine kinematics each require their own orientation
transformation.
Fields of application
The "5-axis transformation" machining package is provided for machine tools, which have
two additional rotary axes (rotation about the linear axes) in addition to three linear axes X, Y
and Z: This package thus allows an axially symmetrical tool (milling cutter, laser beam) to be
oriented in any desired relation to the workpiece in every point of the machining space.
The workpiece is always programmed in the rectangular workpiece coordinate system; any
programmed or set frames rotate and shift this system in relation to the basic system. The
kinematic transformation then converts this information into motion commands of the real
machine axes.
