Departing in a straight line with tangential connection:
DEP LT
The tool moves on a straight line from the last contour point P
the end point P . The line lies on the extension of the last contour
N
element. P is separated from P
N
Program the last contour element with the end point P
radius compensation
Initiate the dialog with the APPR DEP key and DEP LT soft key
LEN: Enter the distance from the last contour
element P
Example
23 L Y+20 RR F100
24 DEP LT LEN12.5 F100
25 L Z+100 FMAX M2
Departing in a straight line perpendicular to the last
contour point: DEP LN
The tool moves on a straight line from the last contour point P
the end point P . The line departs on a perpendicular path from the
N
last contour point P
plus the tool radius.
Program the last contour element with the end point P
