Milling a Line
In the operating mode PROGRAMMING you can use the POSITIP 880 for
milling a line.
Lines are defined by their “FROM” point (the point where they begin)
and “TO” point (the point where they end).
There are two ways you can program a line:
„ With four coordinates(X1, Y1) (X2, Y2)
„ With three of the coordinates above (X1, Y1) or (X2 or Y2) and an
angle.
Choose a method based upon the information available from your
print.
Select the cycle with the LINE soft key, and enter the required data.
See Fig. I.49. This data can usually be taken quite easily from the
workpiece drawing.
The POSITIP 880 calculates the tool path and offers graphic
positioning aid.
