ABSTRACT:
A numerical control system in which a numerical control device is adapted to control a machine tool equipped with a plurality of tables, as one example, on which workpieces may be secured to be machined by a tool mounted on a head. A table which is not being controlled automatically by the numerical control device can be operated independently of the automatic operation network of the numerical control device and placed in a manual operation mode or manual data input mode in which the table can be moved manually even while the numerical control device controls the other table or tables automatically.
