Define a start point
Operating sequences
When entering a contour, begin at a position which you already know and enter it as the
starting point. The sequence of operations for defining the start point of a contour is as
follows:
●
You have opened a part program and selected softkey "Contour" to program a new
contour. The input screen for specifying the start point of the contour is displayed (see
screenshot below).
Figure 7-10 Define a start point
Note
The input field with the input focus is indicated by the dark background color. Once the
input is acknowledged with "Accept element" or "Abort", you can navigate around the
contour chain (left of the screen) using the ↑, ↓ cursor keys. The actual position in the
chain is color-coded.
1.
Select programming plane G17 for the milled part using softkey "Alternative" (or the
"Select key") in the "Selected plane" input field.
The default tool axis or programming plane (defined in the machine data) can be changed
for machines with more than two geometry axes. The associated starting point axes are
automatically adjusted.
Note
Together with defining the contour start point, a pole can also be defined for contour
programming in polar coordinates. The pole can also be defined or redefined at a later
time. The programming of the polar coordinates always refers to the pole that was
defined last.
