Departure On A Circular Path With Tangential Connection: Dep Ct - HEIDENHAIN ITNC 530 - CONVERSATIONAL PROGRAMMING User Manual

Departure on a circular path with tangential
connection: DEP CT
The tool moves on a circular arc from the last contour point P
end point P . The path is tangentially connected to the last contour
N
element.
U Program the last contour element with the end point P
compensation
U Initiate the dialog with the APPR/DEP key and DEP CT soft key:
U
Center angle CCA of the arc
U Radius R of the circular arc
If the tool should depart the workpiece in the
direction of the radius compensation (i.e. to the
right with RR or to the left with RL): Enter R as a
positive value
If the tool should depart the workpiece in the
direction opposite to the radius compensation:
Enter R as a negative value
Example NC blocks
23 L Y+20 RR F100
24 DEP CT CCA 180 R+8 F100
25 L Z+100 FMAX M2
Departing on a circular arc tangentially
connecting the contour and a straight line:
DEP LCT
The tool moves on a circular arc from the last contour point P
auxiliary point P . It then moves on a straight line to the end point P
H
The arc is tangentially connected both to the last contour element and
to the line from P to P . The radius R uniquely defines the arc.
H N
U Program the last contour element with the end point P
compensation
U Initiate the dialog with the APPR/DEP key and DEP LCT soft key:
U Enter the coordinates of the end point P
U Radius R of the circular arc. Enter R as a positive value
