A 3D printer can create parts of any shape by inputting 3D data.Since it is a simple process of stacking melted materials from bottom to top, anyone with data can easily make parts of any shape with full automation.On the other hand, the mainstream method for processing metal parts is to carve out the desired shape from a metal block. Based on the 3D model, the technician will program where and in what order to cut.This method has problems that only engineers with knowledge and experience can do it, it takes time to create a program, and it is difficult to deal with troubles during processing.

　Professor Shirase and his colleagues have developed a method that leaves all the assembly of the cutting procedure to the machine by making the machine tool intelligent.It is possible for a computer to calculate the position and posture of the tool based on the 3D data of the part to be made, and to assemble the procedure sequentially, eliminating the need for programming that was done by a person with knowledge and experience. increase.This makes it possible for anyone to easily perform metal processing as if it were a 3D printer, as long as they have 3D data.

　The development of innovative technologies in manufacturing is also a national focus, and the Cabinet Office is also implementing a strategic innovation creation program.This achievement is one of the research themes being conducted at Kobe University as part of the program, and it is expected that this achievement will greatly contribute to reducing the time and cost required for manufacturing.
