ABSTRACT:
A numerical controller capable of performing path-table operations in a plurality of systems individually or synchronously, such that during a path-table operation in one system, a path-table operation or an operation according to NC statements can be selectively performed in another system. The plurality of systems are provided with their respective reference variables. It is selected whether the reference variable is set common or specific to each of the plurality of systems. During a path-table operation in one system, it is possible to command a path-table operation in another system to start a path-table operation thereof or to perform waiting of path-table operations in the plurality of systems. If the reference variable is set in common for all systems, path-table operations can be performed synchronously, and if the reference variable is set specific to each of the plurality of systems, path-table operations can be performed individually.
