Machine tool and method of machining workpiece

A method of machining a workpiece, the method comprising:

• mounting a workpiece on a table of a work holder;
• first machining of machining the workpiece supported by the table using a first group of rotation tools sequentially held by a machining head of a first machining apparatus;
• second machining of machining the workpiece supported by the table using a second group of rotation tools sequentially held by a multi-joint arm of a first robot;
• and
• turning the table that supports the workpiece about a first axis,
• wherein the first machining comprises moving the machining head using a plurality of linear movers,
• wherein the table supporting the workpiece is turned about the first axis after a part of the first machining and a part of the second machining have been simultaneously performed, and
• wherein the part of the first machining and the part of the second machining are simultaneously performed after the table supporting the workpiece has been turned about the first axis.
