Position the cursor on the "Facing axis dimension" field and click on
the field using softkey "Alternative" (or with the "Selection" key)
repeatedly until the dimension you require is displayed.
Enter the values for the starting point.
The values you have entered are accepted when you select "Accept
element", you can add the next element by selecting the appropriate
softkey.
Beginning at the starting point, enter the first contour element, e.g. a
straight line. Input all the data specified on the workshop drawing:
Length of straight lines, end position, transition to following element,
angle of pitch, etc.
Select softkey "All parameters" to display a selection list of all the
parameters for the contour element.
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.
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:
Straight line in horizontal direction. Enter the end point of the straight
line (incremental/absolute can be selected with softkey "Alternative"),
program the transition to the following element and then press softkey
"Accept element".
Straight line in X direction.
Oblique line in X/Z direction. Enter the end point of the line as a
coordinate or angle.
Arc with any direction of rotation
