10.1 Product brief
Axes for auxiliary movements
In addition to axes for machining a workpiece, modern machine tools can also be equipped
with axes for auxiliary movements, e.g.:
● Axis for tool magazine
● Axis for tool turret
● Axis for workpiece transport
● Axis for pallet transport
● Axis for loader (also multi-axis)
● Axis for tool changer
● Axis for sleeve assembly / end support
The axes for the workpiece machining are called path axes. Within the channel they are
guided by the interpolator such that they start simultaneously, accelerate, reach the end
point and stop together.
Axes for auxiliary movements are traversed independently of the path axes at a separate,
axis-specific feedrate. In the past, many of these axes were moved hydraulically and started
by an auxiliary function in the part program. With the closed-loop axis control implemented in
the NC, the axis can be addressed by name in the part program and its actual position
displayed on the screen.
