Configuring a CNC as two and a half axes
7.17 Configuring a CNC as two and a half axes
A two-and-a-half-axis configuration is a milling machine where the X and Y axes are motorized and
the Z axis is set as a DRO axis (display only). In this configuration, the Z axis is moved manually.
The CNC cycles and interface have been adapted for this type of configuration.
Cycle editing and execution
The cycles are edited, stored and simulated just like a 3-axis configuration.
The most significant different lays in the execution because the operator must move the Z axis by
hand. The standard screen shows the operations to be carried out by the operator. In each case,
it shows the status of the Z axis and the various actions to be executed by the operator.
• Move Z up (it shows an icon next to the final Z coordinate).
The operator must move the axis up manually. When the Z axis is in position, the message will
change.
• Move Z down (it shows an icon next to the final Z coordinate).
The operator must move the axis down manually. When the Z axis is in position, the message
will change.
• Press [CYCLE START].
The operator must press [CYCLE START] to begin the automatic movement in the X-Y plane.
•Moving in X-Y.
The machine is moving in X-Y. When a Z axis move is required, the machine will stop and it will
request the operator's intervention.
• Tool inspection.
It went into tool inspection.
Canned cycles
Not all the cycles can be applied to a two-and-a-half-axis configuration. The forbidden cycles may
be hidden by machine parameters.
In some of the permitted cycles, some data has been eliminated to adapt the cycle to the two-and-
a-half-axis configuration. The eliminated data is the one referring to the Z axis operations.
