Defining The Working Plane With Two Vectors: Plane Vector - HEIDENHAIN TNC 620 User Manual

Defining the working plane with two vectors:
PLANE VECTOR
Application
You can use the definition of a working plane via two vectors if your
CAD system can calculate the base vector and normal vector of the
tilted machining plane. A normalized input is not necessary. The
control internally calculates the normal, so you can enter values
between -9.999999 and +9.999999.
The base vector required for the definition of the machining plane
is defined by the components BX, BY and BZ. The normal vector is
defined by the components NX, NY and NZ.
Programming notes:
The control calculates standardized vectors from the
values you enter.
The normal vector defines the slope and the
orientation of the working plane. The base vector
defines the orientation of the main axis X in the
defined working plane. To ensure that the definition of
the working plane is unambiguous, you must program
the vectors perpendicular to each other. The machine
tool builder defines how the control will behave for
vectors that are not perpendicular.
The programmed normal vector must not be too
short, e.g. all directional components having a length
of 0 or 0.0000001. In this case, the control would not
be able to determine the slope. Machining is aborted
and an error message is displayed. This behavior
is independent of the configuration of the machine
parameters.
You can select the desired positioning behavior.
