Position the cursor on the "Transverse axis dimension" field and click
on the field using the "Alternative" softkey (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" and you can then add the next element by selecting the
appropriate softkey.
Sequence of operations
From the starting point enter the first contour element, e.g.,, straight
line. Enter all of the data from the workpiece drawing: Length of
straight lines, end position, transition to following element, angle of
pitch, etc.
Select the "All parameters" softkey 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 these from
the settings of the 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 bar; 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 the horizontal direction. Enter the end point of the
straight line (incremental/absolute can be selected with the
"Alternative" softkey), program the transition to the following element
and then press the "Accept element" softkey.
Straight line in the X direction.
Oblique line in the X/Z direction. Enter the end point of the line using
coordinates or an angle.
Arc with any direction of rotation
