G Functions for Machining

The following functions must be preceded with the section
code MACHINING.

For contour-based turning cycles define the reference to the
contour description in ”NS, NE.” You can determine this
reference as follows:

Activate contour display (menu item ”Graphic”).
Place the cursor on the ”NS/NE” field and press the

Continue key.

Select the desired contour element with the left/right arrow

key.

The up/down arrow keys can be used to switch between

several contours (also end face contours, etc.)

Transfer the block number of the contour element (”Enter”

key).

If you activate the up/down arrow keys, the
CNC PILOT also considers contours that are not
displayed on the screen.
