Abstract:
A machine tool that attaches and detaches workpieces to and from a spindle in a shorter time includes: a machining mechanism part including a spindle, a tool rest, a first-axis feed mechanism moving the spindle in a a first axis extending along a center axis of the spindle, and a second-axis feed mechanism relatively moving the spindle and the tool rest in a second axis orthogonal to the first axis; a loading mechanism part including holding parts for holding a workpiece, and a third-axis feed mechanism moving the holding parts in a third axis orthogonal to the first axis to position them at the transfer position; and a numerical controller. The numerical controller operates to move the spindle toward the transfer position and to position the holding parts at the transfer position such that the operations at least partially overlap.

Claim (Index 8):
The machine tool according to  claim 5 , wherein the numerical controller is configured to,\n when executing a machining program containing a position command for a workpiece coordinate system having its origin at a workpiece zero point, and numerically controlling the first-axis feed mechanism and the second-axis feed mechanism with respect to a machine coordinate system having its origin at a machine zero point, numerically control the first-axis feed mechanism and the second-axis feed mechanism using a workpiece offset amount for compensating for a difference between the workpiece zero point and the machine zero point, and when executing the workpiece transfer operation program containing a position command for the machine coordinate system, and numerically controlling the first-axis feed mechanism and the third-axis feed mechanism with respect to the machine coordinate system, numerically control the first-axis feed mechanism and the third-axis feed mechanism without using the workpiece offset amount.
