The study deals with the development of a movable machine tools with multi spindles and axes that can efficiently process large-sized parts to expect an additional value. The main specification of the machine tool is not having the major construction such as bed, column and saddle absolutely. Instead, the machine tool is built by only linear motor rails and beams to support. The developed machine tool can reduce the cycle time for cutting large materials by means of multi spindles and axes, equipped with 6 to 9 spindles and simultaneously control up to 40 at maximum. In addition the installation area of the machine tool is approximately 120% of area that the material occupies. The previous report explained the basic specification of the machine tool, its concept and performance evaluation. Then, this report presents the management of simultaneous movement, the division of NC program for each spindle and interference avoidance of multi axes, as well as the method of tool path generation to confirm the rapid production of large sized die and mold.
