Circle Center Cci - HEIDENHAIN ITNC 530 - CONVERSATIONAL PROGRAMMING User Manual

Circle center CCI

You can define a circle center for circles that you have programmed
with the C key (circular path C). This is done in the following ways:
Entering the Cartesian coordinates of the circle center in the
working plane, or
Using the circle center defined in an earlier block, or
Capturing the coordinates with the ACTUAL-POSITION-CAPTURE
key
U Enter the coordinates for the circle center, or
If you want to use the last programmed position,
enter no coordinates
Example NC blocks
5 CC X+25 Y+25
or
10 L X+25 Y+25
11 CC
The program blocks 10 and 11 do not refer to the illustration.
Duration of effect
The circle center definition remains in effect until a new circle center
is programmed. You can also define a circle center for the secondary
axes U, V and W.
Entering the circle center incrementally
If you enter the circle center with incremental coordinates, you have
programmed it relative to the last programmed position of the tool.
The only effect of CC is to define a position as circle
center: The tool does not move to this position.
The circle center is also the pole for polar coordinates.
