Regarding 3, the sprockets 9 and 10 are rotated appropriately to position the tools 13 to be used one after another at the tool holding position X and continue machining, but the tool 13 stored in the supplementary tool magazine 20 is used. In this case, move the carriage 3 in the Z-axis direction and the Cutroslide 5 in the X-axis direction to a predetermined tool exchange position, drive the tool exchange device 16 there, and store the tools in the replenishment tool magazine 20. Tool 13
are stored in the tool magazine 7, and the tools 13 that are no longer needed in the tool magazine 7 are returned to the replenishment tool magazine 20. The tool exchange operation by the tool exchange device 16 is performed by first positioning the tools 13, 13 to be exchanged at predetermined tool exchange positions Z1, Z2, and then
The ATC arm 17 is made to protrude in the direction of arrow A and perpendicular to the plane of the paper, and the tools 13, 13 are grasped by the tool gripping parts 13a, 13a provided at both ends, and in this state, the ATC arm 17 is retreated in the direction B. Then pull out the tool 13 from the tool holding pocket 12, and in that state, remove the ATC arm 17.
By rotating the tool 180°, the tool 13 that had been stored in the tool magazine 7 is positioned on the replenishment tool magazine 20 side, and the tool 13 that was stored in the replenishment tool magazine 20 is positioned on the tool magazine 7 side. Therefore, when the ATC arm 17 is made to protrude in the A direction again, the tools 13 are held in their respective tool holding pockets 12.
The tools 13 that were previously stored in the replenishment tool magazine 20 are stored in the tool magazine 7, and the tools 13 that were stored in the tool magazine 7 are stored in the replenishment tool magazine 20. Therefore, the tool 13 stored in the tool magazine 7 from the supplementary tool magazine 20 is positioned at the tool holding position X, and the tool 13 is held from the tool holding table 6 to perform a predetermined machining.

The machining program PRO inside includes:
As shown in FIG. 4, an exchange command (in the figure, T
Command by code. ) exists each time machining for one tool 13 is completed. Therefore, before the main control section 21 causes the mechanism control section 29 to perform machining based on the machining program PRO, it instructs the tool exchange control section 25 to read in advance the machining program PRO to be executed next. Then, the tool change control section 25
reads the machining program PRO to be executed next from the machining program memory 23, reads the machining program PRO in advance, and executes the machining program PRO.
The tools 13 scheduled to be used in the PRO are extracted and stored in the exchange tool memory 30. Next, the tool 13 currently stored in the tool magazine memory 26 and the tool 13 in the replacement tool memory 30 are compared, and the tool 13 required for the next machining is determined. A tool 13 that is not currently stored in the tool magazine 7 but is stored in the replenishment tool magazine 20 is extracted and selected, and a predetermined flag is set in the address corresponding to the tool 13 in the replacement tool memory 30 for the tool 13. attach

A plurality of tools 13 are provided on the intermediate joint so as to be able to be selectively positioned at a bent part such as the sprocket 9 portion of the intermediate joint, and the tool holding table 6 is provided so that the tool holding stand 6 can freely hold the tool positioned at the bent portion on the intermediate joint while being held on the intermediate joint, and furthermore, the tool magazine is attached to the main shaft together with the tool holding stand. One or more replenishment tool magazines 20 which are movable synchronously in the axial direction and the direction perpendicular thereto and store a plurality of tools are provided, and a tool exchange device is provided between the tool magazines and the replenishment tool magazines. A tool exchange means such as 16 is provided, and a memory means such as a machining program memory 23 is provided which stores a machining program PRO to be executed, and the machining program to be executed is read out from the memory means in advance and used in the machining program. A used tool extracting means such as a tool change control unit 25 for extracting a tool to be used is provided, and among the tools to be used extracted from the used tool extracting means, the replenishment tool is not stored in the tool magazine. A replenishment tool selection and extraction means such as a tool exchange control unit 25 for selectively extracting replenishment tools stored in a magazine is provided, and the replenishment tools selected and extracted by the replenishment tool selection and extraction means are transferred to the replenishment tool magazine. Since the configuration is provided with tool replenishment command means such as the main control unit 21 that instructs the tool exchange means to replenish the tool magazine at once from the tool magazine 7, the shortage of tools in the tool magazine 7 can be easily detected.
This can be compensated for by exchanging tools between the tool magazine and the replenishment tool magazine using the tool exchange means, and a large number of tools can be used even if the tool magazine on the tool holding stand side is not very large. By downsizing the tool magazine on the table side, the time required for tool exchange (time required for selecting a target tool) can be reduced as much as possible.

での干渉の発生を極力防止することができる。 Note that even if many tools are attached to the wrapping joint, adjacent tools will separate from each other at the bend, so there will be space between the tool used for machining and other tools, and between the tool used for machining and the workpiece. It is possible to prevent interference between the two as much as possible.

Regarding tools 13 that should be used in PRO,
The tools extracted by the used tool extraction means and the replenishment tool selection means are replenished at once by the tool exchange means via the tool replenishment command means, and are already stored in the tool magazine 7. During the execution of machining, it is possible to avoid as much as possible the time-consuming tool exchange operation that would be required if the tools 13 stored in the replenishment tool magazine 20 are taken out one by one, and it is possible to perform highly efficient machining operations. In addition, the number of tool exchange operations during machining is greatly reduced, so you can use this time to
It is also possible to easily supply and replenish tools to the replenishment tool magazine 20.
