A tool or a workpiece is fed by the cut feed by cut feed commands during periods when the tool or the workpiece would normally be fed by rapid feed. These periods are chosen to occur when the distance of the sections to be fed is a predetermined distance or less. Then, in the case that the feeding distance is the predetermined distance or less, the tool or the workpiece can be fed more rapidly by cut feed rather than rapid feed. Thus, machining time is shortened to that extent.

Feed control method in a numerically controlled machine tool

A method of controlling the indexing of magazine pockets in a machining center. The tools used in a current machining program are compared with the tools to be employed in the next machining program. When there are tools used in both programs, the pocket numbers of the tools in the present machining program are indexed to the identical tools to be used in the next machining program. The data concerning such common tools are displayed together with the indexed pocket numbers.
