Selecting A Tool And Machining Plane - Siemens SINUMERIK 840D sl Turning Operating Manual

Programming technology functions (cycles)
10.7 Additional cycles and functions in ShopTurn
● Straight line with polar coordinates
● Circle with polar coordinates
If you want to program a straight line or a circle using polar coordinates, you must define the
pole first.
NOTICE
Risk of collision
If you retract the tool to the retraction area defined in the program header using either straight
or circular path motion, then you must carefully ensure that a collision cannot occur as a result
of the normal retraction logic.
To be on the safe side, you should also move the tool back out of the retraction area again.
10.7.10

Selecting a tool and machining plane

Before you can program a line or circle, you have to select the tool, spindle, spindle speed and
machining plane.
If you program a sequence of different straight or circular path motions, the settings for the tool,
spindle, spindle speed and machining plane remain active until you change them again.
If you change the selected machining plane subsequently, the coordinates of the programmed
path motion are automatically adjusted to the new machining plane. The originally programmed
coordinates remain unchanged only for a straight motion (right-angled, not polar).
Procedure
