5.1 Simulation Mode of Operation
Status of the zero point shifts
Zero point shifts are included in
calculation
Zero point shifts are not included in
calculation
A change of status is not accounted for
until the simulation is restarted.The
symbols are shown faded as long as the
changed setting is not yet in effect.
Several workpieces in the working space
The CNC PILOT depicts up to four workpieces in the working space
and simulates machining of these workpieces. You define the (first)
position of the workpiece in CONTOUR. It is possible to shift the
workpiece position later with G99.
Zero point shift
In the ”Contour selection” dialog box (”Set up – Contour selection”)
you define whether zero point shifts will be accounted for in the
simulation. – As an alternative you can use the touch pad to click the
”zero point shifts” symbol in order to change the setting.
Changed settings do not become effective until the simulation is
restarted.
Including zero point shifts:
■ The machine zero point is the reference point for the positioning of
contours and for the traverse paths.
■ Zero point shifts are included in calculation
Zero point shifts are not included in calculation:
■ The workpiece zero point is the reference point for the paths of
traverse
■ Zero point shifts are ignored
If you use the program section code CONTOUR and G99, no matter
what the status of the zero point shift:
■ The workpiece (the contour) is depicted at the position defined in
CONTOUR
■ G99 X.. Z.. shifts the workpiece to a new position
Coordinate systems of the contours
■ Qn (n: 1..4): Contour n – the selected
contour is marked
■ Symbol: Coordinate system of this
contour
