The hypernym Dynamic Precision stands
for a number of HEIDENHAIN solutions for
milling that can dramatically improve the
dynamic accuracy of a machine tool. It is
the result of a new perspective on the
competing demand for accuracy, high
surface quality and short machining times.
The dynamic accuracy of machine tools
can be seen in position errors at the Tool
Center Point (TCP), which depend on the
motion quantities such as velocity and
acceleration (also jerk) and result from
vibrations of machine components and
other causes.
All the deviations are together responsible
for dimensional errors and faults in the
workpiece surface. They therefore have a
decisive influence on quality and, when
poor-quality parts are scrapped, also on
productivity.
Because the stiffness of machine tools is
limited for reasons of design and economy,
problems such as compliance and vibration
within the machine design are very difficult
to avoid. Dynamic Precision counteracts
these problems with intelligent control
technology to enable designers to further
improve the quality and dynamic perfor-
mance of machine tools. That saves time
and money in production.
The machine tool builder can use the
options comprised by Dynamic Precision
either individually or in combination:
• CTC – Compensation of position errors
through compliance between the
machine and TCP, thereby increasing
accuracy during acceleration phases
• AVD – Active vibration damping
improves surfaces
• PAC – Position-dependent adaptation of
controller parameters
• LAC – Load-dependent adaptation of
control parameters enhances accuracy
regardless of load and aging
• MAC – Motion-dependent adaptation of
control parameters
Quick and reliable machining with high contour accuracy
