Contour transition
elements
A transition element can be used whenever there is a point of
intersection between two neighboring elements which can be
calculated from the input values.
You can choose between a radius RD and a chamfer FS to be
inserted as the transition between any two contour elements. The
transition is always appended to the end of a contour element. You
select transition elements in the parameter input screen form for the
relevant contour element.
Abort
When you select "Abort", the contour element values are discarded
and you return to the basic display. The input focus switches back to
the contour chain.
Delete
value
The values for the element are deleted.
Parameters
on gray background
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.
Input value
is already calculated
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.
Free text input
Under "Free text input" you can enter a comment that is inserted in
the program at the end of the contour (e.g. specifying the technology,
feedrate, M function).
Contour allowance
(SW 6.3 and higher)
By selecting "Cont. allow.", you can specify the allowance parallel to
the contour and the side of the contour on which the allowance
applies. It is displayed as an allowance in the graph window.
It is possible to change the allowance and the parameters from the
original contour. These changes are applied to subsequent machining
operations in the part program, e.g. for grinding.
