Parametric Programming - Definition
Parametric programming is similar to macro programming in that equations can be used
to specify axis position rather than decimal numbers. The 9000 CNC does not restrict the
use of parametrics to subroutines or macros. They may be used anywhere throughout
a program. Parametric expressions may be used to specify M, G, F, and S functions.
When a parametric expression is used for an axis position, it will first be evaluated and
then cutter compensation will be applied. All the normal cutter compensation rules will apply
to the evaluated point. Values generated by equations may be displayed on user parameter
screens. Other listed system parameters may be used as input data to parametric equations,
but under normal circumstances these parameters should not be changed.
