The surface-normal vector affects the compensation for the end-point of the move commanded on the
same line as the surface-normal vector. It also affects the compensation for subsequent moves until
another surface-normal vector is declared. In typical use, a new surface-normal vector is declared with
each move, so the vector only affects the move on the same line in this case.

Example:

X3.76 Y8.29 Z-4.83 A34.32 C-29.75 NX0.866 NY0 NZ-0.5

Function:

Set 3D-comp surface-normal vector Y-component

Type:

Motion program (PROG and ROT)

Syntax:

NY{data}

where:



{data} is a signed floating-point constant or expression representing the Y-component of the
surface-normal vector

This statement specifies the Y-component of the surface-normal vector used for three-dimensional cutter-
radius compensation. This value is used along with the X and Z-components specified by the NX{data}
and NZ{data} statements, respectively, to compute the orientation of the vector.

The total magnitude of the surface-normal vector specified with these three components does not matter,
although a unit-magnitude vector is typically specified.  The relative magnitudes (including signs) of the
three components are what determine the orientation of the vector.  The vector must be defined from the
surface toward the tool.  Generally, all three components be declared together on one line; if only one or
two components are declared, the others are left at their old values, possibly leading to unpredictable
results.

X3.76 Y8.29 Z-4.83 A34.32 C-29.75 NX0.866 NY0 NZ-0.5
