6.5 Free contour programming
When you have created a new contour and specified the start point,
you can define the individual elements that the contour comprises.
If you leave any parameter input fields blank, the control assumes that
you do not know the right values and attempts to calculate them from
the settings of other parameters.
The contour is always machined in the programmed direction.
As soon as you have entered an element, the input focus is moved to
the contour chain on the left of the graphic display. The input focus
has a yellow border. You can navigate within the contour chain using
the cursor keys.
You can select an existing contour element with "INPUT". A new
contour element is inserted after the cursor when you select one of
the contour elements on the horizontal softkey menu; the input focus
is then switched to the parameter input on the right of the graphic
display. You can navigate around the contour chain again after
selecting "Accept element" or "Abort". The following contour elements
(example for turning: G18) are available for the definition of contours.
Select a contour element via softkey.
Enter all the data available from the workpiece drawing in the input
form (e.g. length of straight line, target position, transition to next
element, angle of lead, etc.).
Press the "Accept element" softkey to accept all values.
The contour element is added to the contour. Repeat the procedure
until the contour is complete.
The individual contour elements are listed. Use the cursor keys to
select the element in front of the end marker.
Select the required contour element via softkey.
Press the "Accept element" softkey.
The required contour element is appended to the contour.
Use the cursor keys to select the contour element behind which you
wish to insert another element.
