The following are contour elements:
Starting point
Straight line (planar, longitudinal, inclined)
Circular arc
A pole is a pseudo contour element. Straight lines and circular arcs
can also be defined by polar coordinates in reference to a pole.
Additional information
1. The valid geometry axes in the first channel are determined and
used in the part program.
2. The contour editor uses the last programmed axis position for the
starting point, without allowing for previously valid G functions.
3. You must also specify the side on which the contour allowance
should lie, e.g., "right" or "left".
Sequence of operations
Use the "Workpiece" and "Part program" softkeys in the Program
operating area to select an existing program and press the "Input" key
or open a new part program using the "New" softkey, enter a name
and confirm with "OK". You are now in the ASCII editor.
The "Contour" softkey displays a vertical softkey bar with the following
options:
The contour calculator is activated to generate a contour chain from
contour elements.
Preparatory cycles are displayed with help displays for creating
straight lines and transition elements, if applicable.
You can edit an existing contour by selecting the "Recompile" softkey.
The editor cursor must be positioned inside the contour to do this.
