ABSTRACT:
A numerical control device for a multi-axis lathe which is capable of controlling movements of a plurality of tools simultaneously. With the numerical control device, the movement of a first tool in a Z-axis direction is controlled according to the movement of a workpiece to be machined and the other movement of remaining tools in the Z-axis direction are controlled taking the Z-axis movement of the first tool into consideration, so that the different machining operations using different tools can be attained simultaneously or successively.
