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

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.

O{constant}
Function:
Alternate Line Label
Type:
Motion program (PROG and ROT)
Syntax:
O{constant}

{constant} is an integer from 0 to 262,143 (2

This is an alternate form of label in the motion program. It allows the flow of execution to jump to that
line with a GOTO, GOSUB, CALL, G, M, T, or D statement or a B command.

Turbo PMAC will store and report this as an N{constant} statement, but O labels are legal to send to
the program buffer. (N10 and O10 are identical labels to Turbo PMAC.)
the program buffer. (N10 and O10 are identical labels to Turbo PMAC.)
A line only needs a label if the user wishes to be able to jump to that line. Line labels do not have to be in
any sort of numerical order. The label must be at the beginning of a line. Remember that each location
label takes up space in Turbo PMAC memory.
