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 TNC 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 (see figure at right). The
normal vector is defined by the components
NX, NY and NZ.
Before programming, note the following
The base vector defines the direction of the
principal axis in the tilted machining plane, and the
normal vector determines the orientation of the
tilted machining plane, and at the same time is
perpendicular to it.
The TNC calculates standardized vectors from the
values you enter.
