PURPOSE:To improve operating efficiency and reduce the number of tools by exchanging only a necessary tool between a tool bulk storage and an automatic tool feeding buffer by a conveying vehicle via a tool cassette and, then, loading said tool on a tool housing device and starting machining. CONSTITUTION:A required exchanging tool 11a and its positions in a tool cassette 11 and in a housing device 21b are outputted from a control computer 400 based on a data file, and the tool is conveyed between a tool bulk storage and an automatic tool feeding buffer 10 by means of a conveying vehicle 3 via a cassette 11 by a control device 300. In the case of exchange of a tool 11a to be mounted on plural machining centers 2 by a control device 200, the necessary tool 11a is fed to the prescribed position of the housing device 21b of an automatic tool changer 21 from the cassette 11 of the buffer 10 through an exchange means 10a by a control device 100. Accordingly, the exchange can be carried out without interrupting cutting and a tool which is not in use can be returned, thereby, reducing the number of tools. |
