Axes Management
Coordinated, Auxiliary, Pseudo and Spindle axes
The OPENcontrol CNC can manage different kinds of axes:
Coordinated Axes (or Process axes) moved by the Operator via manual or
programmed movements. They are managed by the Process Interpolator.
Auxiliary Axes moved by the Machine Logic and managed by a number of Auxiliary
Interpolators that have the same characteristics and potentiality of the coordinated
axes interpolator.
Pseudo Axes. They are used to send information from the part program to the
machine logic.
Spindle axes are those to which tools are normally fitted. They are controlled
by the Machine Logic and managed by a specific Interpolator. One spindle can be
configured for each process and hence up to 24 spindles. Moreover, it is possible to
share or exchange spindles between processes
With the CNC systems up to 12 axes (12 coordinated axes, 6 pseudo axes) can be
programmed in the same part program block. The Machine Logic can manage up to 40
interpolators with dynamic axes conguration. Also in this case, up to 12 axes can be
interpolated by each interpolator.
Linear and Rotary Axes
Both coordinated and auxiliary axes can be declared as linear (programmed in mm or
inches) or rotary (programmed in degrees).
Rollover Axes
Linear or rotary axes whose position is always displayed in the range from zero to a
maximum congurable positive value (“rollover pitch”). These axes can be programmed
either in absolute or incremental mode.
Diameter Axes
For a diameter axis, the programmed position is twice the actual movement. This
programming mode is typically used in cylindrical geometry machines (lathes or grinding
machines).
Dual Axes (UDA, SDA)
Dual axes are two or more physical axes that follow an identical path (typically in Multi-
head machines). One is the "master" programmed by the Machine Operator, while the
others are "slaves" commanded by the system to follow the master movements (directly
or in mirror mode).
The link between master and slaves is enabled or disabled by the part program. It is
possible to program up to 6 master axes and up to 17 slave axes for each master.
