p 3.5 Machine setup
The machine always requires a few preparations, regardless of
whether you are machining a workpiece manually or automatically. In
Manual mode the following functions are subitems of the Setup menu
item:
 Setting the axis values (defining workpiece zero point)
 Machine reference (axis reference run)
 Setting the protection zone
 Defining the tool change position
 Setting C-axis values
Defining the workpiece zero point
In the dialog, the distance between the machine zero point and the
workpiece zero point (also know as offset) is shown as XN and ZN. If
the workpiece zero point is changed, the display values will be
changed accordingly.
Select Setting up
Select Set axis values
Touch the workpiece zero point (end face)
Define this point as the "workpiece zero point Z"
Enter the distance between the tool and the workpiece zero point as
"measuring point coordinate Z"
The CNC PILOT calculates the workpiece zero
point Z
The workpiece datum can now also be set in the direction
of the Z axis using a touch probe. When setting the zero
point, the control checks which type of tool is currently
active. If you select the Workpiece zero point setup
function and a touch probe is inserted, the control
automatically adjusts the input form. Press NC Start to
start the measuring process. Press the Save soft key to
apply the measured value as workpiece zero point in the Z
axis.
