Approaching On A Straight Line With Tangential Connection: Appr Lt; Approaching On A Straight Line Perpendicular To The First Contour Point: Appr Ln - HEIDENHAIN ITNC 530 - CONVERSATIONAL PROGRAMMING User Manual

Approaching on a straight line with tangential
connection: APPR LT
The tool moves on a straight line from the starting point P
auxiliary point P . It then moves to the first contour point P
H
straight line that connects tangentially to the contour. The auxiliary
point P is separated from the first contour point P

LEN.
U Use any path function to approach the starting point P
U Initiate the dialog with the APPR/DEP key and APPR LT soft key:
U
Coordinates of the first contour point P
U LEN: Distance from the auxiliary point P
contour point P
U Radius compensation RR/RL for machining

Approaching on a straight line perpendicular to
the first contour point: APPR LN
The tool moves on a straight line from the starting point P
auxiliary point P . It then moves to the first contour point P
H
straight line perpendicular to the first contour element. The auxiliary
point P is separated by the distance LEN plus the tool radius from the
H
first contour point P .
