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.

“Specifying the Positioning Behavior of the PLANE 
Function,” page 460.
