Deactivating Function Polarkin - HEIDENHAIN TNC 620 User Manual

Notes
Programming notes:
Before activating the polar kinematics, you must program the
function PARAXCOMP DISPLAY with at least the principal axes X,
Y, and Z.
HEIDENHAIN recommends defining all of the available
axes within the PARAXCOMP DISPLAY function.
Position the linear axis that will not be included in the polar
kinematics to the coordinate of the pole, before the POLARKIN
function. Otherwise, a non-machinable area with a radius that
corresponds to at least the value of the deselected linear axis
would result.
Avoid performing machining operations at the pole or near the
pole, because fluctuations in feed rate may occur in this area. For
this reason, ideally use the following POLE option: SKIPPED.
Polar kinematics cannot be combined with the following
functions:
Traverse motions with M91
Tilting the working plane
FUNCTION TCPM or M128
Machining information:
The polar kinematics may require continuous motions to be divided
into submotions (e.g., a linear motion that is divided into two
submotions: a motion for approaching the pole and a motion for
departing the pole). As a result, the distance-to-go display may differ
from that of the standard kinematics.

Deactivating FUNCTION POLARKIN

Use the POLARKIN OFF function to deactivate the polar kinematics.
Program this as follows:
Show the soft key row with special functions
Press the PROGRAM FUNCTIONS soft key
Press the POLARKIN soft key
Press the POLARKIN OFF soft key
Example
6 POLARKIN OFF
When the polar kinematics is not active, the control does not display
the corresponding icon or entries on the POS tab.
