ABSTRACT:
A numerical control method for controlling a machine tool having a plurality of turrets including supplying a control device with data items indicative of cutting conditions for respective tools mounted on the turrets, a machining program, and material conditions of a workpiece to be cut by the machine tool for computing a capability required to cut the workpiece based on the supplied data items. It is then determined whether the value of the capability exceeds a range of an allowable capability of the machine tool or the tools. An output is issued to reduce the cutting conditions when the value of the capability exceeds the allowable capability range to correct the capability required to cut the workpiece to the allowable capability range of the machine tool or the tools. The reduced cutting conditions are issued to the machine tool for machining the workpiece.
