6.11 Machine Kinematics (As of NC Software 548328-03)
As of software version 548328-03, a new kinematic model is available for
describing the machine kinematics of the MANUALplus 620. The
MANUALplus 620 can be operated as selected with the old or the new
kinematic model. The use of KinematicsDesign is possible only with the new
kinematic model, which is also activated in the factory default condition.
Machine parameters in the MANUALplus 620 describe the machine
kinematics. It is a precondition that the kinematic models consist of translation
axes and rotation axes which are linked to each other. This structure can also
be used for configuring axes that are not perpendicular with respect to each
other.
Multiple sets of kinematics can be configured for one machining channel.
Multiple sets of kinematics are needed, for example, if the spindle and C axis
on a lathe are driven by the same motor. The kinematics description consists
of a transformation chain, starting from the tool reference point to the the
linear axes, all the way to the last axis or transformation.
The transformation chain consists of
fixed lengths (machine dimensions)
variable lengths (linear axes)
fixed rotations (machine conditions)
variable rotations (rotary axes)
starting from the tool reference point (e.g. spindle housing, machine base,
linear axes, machine envelope). Each translation is described.
All machine axes in the kinematic model are described in the position REF=0
(machine center).
The KinematicsDesign software for PCs can only be used in conjunction
with the new kinematic model described below.
