9.5 Defining the Machining Plane
with Two Vectors:
VECTOR PLANE
Function
You can use the definition of a machining 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 –99.999999
and +99.999999.
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.
The base vector defines the direction of the X axis in the tilted
machining plane, and the normal vector determines the direction of
the machining plane, and at the same time is perpendicular to it.
Before programming, note the following:
The TNC calculates standardized vectors from the values
you enter.
