ではＮ０Ｏ７）を探し出す。By the way, the conventional mekuken sequence search function finds the machine sequence number that includes the tool position when machining was interrupted, and uses the sequence number search function to run the NC program at the sequence number position that is one sequence number before the machine sequence number. Load it into NC memory. Then, by restarting the tool, the tool returns from the retracted position to the command value of the read sequence number, and then executes the machining sequence that was used when machining was interrupted. That is, as shown in the lathe machining diagram in FIG. 1 and the machine program in FIG. 2, the workpiece 2 is shaped into the final shape P8-
Considering the case of cutting Pb-Po-Pd...
Point P in fast forward α river at sequence number N0OI. Then, at sequence number N0O2, cutting feed Go
The program is created according to the following sequence: to point P1 at l (feed rate MP), then to point P2 at sequence number N0O3, and so on. If a problem occurs at point Ps while cutting is being performed according to the cutting program, the operator must stop cutting, move the tool 1 to a safe retreat position f"l"IL, and Necessary operations such as replacement and dimension measurement are performed, but when attempting to continue machining again, the sequence number (N0O7 in this example) that includes the point PS where machining was interrupted is searched.

Since it is set to move (3) where it has already been cut, there is a time loss, and the distance M (P4-
If Ps) is large, damage will become a problem. In addition, in the case of a command program without a sequence number, there is a drawback that the sequence cannot be restored. Cases without a sequence number are typified by complex cutting cycles/automatic program cutting functions, etc. Built-in computer
C0) This is a case where the computer has a function to automatically calculate the Canadian program. Taking the machining process shown in Figure 1 as an example, if only the final shape Pa-Pb-Po is programmed as shown in Figure 3, all intermediate cutting paths will be automatically calculated. It is something that However, when cutting is performed using such a cutting program and the machining is interrupted at the point Ps, the problem is how to return to that position and continue the machining. SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a sequence post-tightening method that does not have the above-mentioned drawbacks.

While the movement of the table is locked, the NC function generator is operated for 10 seconds) to come to the point PsAlt on the machining trajectory. When the operator inputs the sequence return signal SR after completing the approximation operation, the approximate points obtained by the approximation operation and the prepared state of the NC function generator 10 at that time are stored in the state save register via G3. 16, the tool cutting edge of the tool rest is moved in rapid traverse to the displayed approximate point (PsA). In other words, the modern point is a state save register]
6 to the command register 11, and the NC function generator 10
outputs the machining trajectory up to the point P)(,→approximate point.The prepared state of the NC function generator 10, which is evacuated by the sequence return signal SR, is the state in which the NC function generator 10 is prepared in the normal NC manual interrupt function. This is used as P4 in Figure 1→
Therefore, when the operator inputs the start signal ST, the NC function generator 1 saved in the status save register 16 can be continued.
The state of 0 is transferred to the NC function generator 10 via G5, thereby making it possible to continue cutting from the approximate point (PsA).
