摘要： PURPOSE:To reduce a required storage space by coding tool holders with specific discrimination codes, coding blades to be installed with information discrimination codes, memorizing, sorting and storing them in a management means, and selecting and combining them when necessary. CONSTITUTION:A memory element 3 is embedded in the forward end surface of a tool holder 1 to make it possible to write and read information. A blade 4 is also provided with a discrimination code 9 based on the number of ring grooves 5, etc. After use, the length of the blade 4 is measured by means of a measuring machine 6, and the code is discriminated by a CCD camera 9 and inputted to a personal computer 8. For the tool holder 1, also, a discrimination code in the memory element 3 is read by a reader 7 and inputted to the personal computer 8, and both are memorized. The tool holder 1 and the blade 4 are stored in a storage rack separately. When necessary, selected holder 1 and blade 4 are assembled by a management person and transferred to a magazine. A required storage space can thus be reduced.

摘要： PURPOSE:To control the position of the tool by figuring out a positional value on the basis of border wear amount at the rear side of an end of the tool in the direction of feeding the tool at a position corresponding to a half of feed amount per one rotation to send the output to the input of a numerical control unit. CONSTITUTION:In a numerical control lathe, a probe 14 of an electric micrometer 13 is moved Ao by an end 16 of a tool 10 when the tool 10 is slided to a predetermined position in the direction of cut, and this Ao is a initial value of the end 16 of the tool. Also, Bo is a positional value corresponding to 1/2 of feed f of the tool 10 per one revolution in the rear side of the tool end 16 in the direction of feeding the tool 10, i.e. when Bo value in a border wear portion 17 is detected, a carriage 7 is first located at a position offset by f/2 from that in which the end 16 is detected, and then only an inner bed 8 is slided in the cut direction of the tool 10. Thus, the position of the tool can be controlled.
