Program Operating Area

Input value
is already calculated
Further information
The NC code generated by the contour programming in the part
program must never be altered manually. Otherwise recompilation is
no longer possible.
Exception: Insertion of block numbers and masking blocks.
These parameters have been calculated by the control system. You
cannot alter them.
When the programmed parameter input fields (white background) are
altered, the control calculates new data, which are then immediately
displayed again in the input screen form.
With some contours, the control system may already have calculated
an input value from other settings.
Problems may then arise if the control-calculated value does not tally
with the workshop drawing. In this case, you must delete the settings
from which the control has automatically calculated the input value.
You can then enter the setting exactly from the workshop drawing.
The technology (turning/milling) and the position of the coordinate
system are read from the appropriate machine data. You can see the
selected configuration with "Settings".
