Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Tool changing thinking of the present invention is tool changing to be got nowhere be regarded as machine failure, could process after need handling well earlier.On general tool changing logic flow, after each work step interrupted, the different situations that occur are marked and processed, specifically see Fig. 2.
Interrupting on the flow process of tool changing, needing mark tool changing commencing signal, tool changing end signal.These two signals use the M code in the Siemens system to realize.Be beginning tool changing signal like " M84 ", " M85 " is the tool changing end signal, refreshes cutter table simultaneously and puts in place this step at tight cutter.Therefore, can handle under the various states by the result after interrupting with table 1.
The various situation of table 1 system when quilt interrupts tool changing
Situation analysis:
1. sequence number 1, sequence number 2, sequence number 9, sequence number 10: this four step is interrupted, and the tool magazine position is in the original position that puts in place of shifting out, and the main shaft cutter number equals tool magazine cutter number; Cutter on the cutter table number equals main shaft cutter number; Therefore, the cutter that tool changing next time can swap out normally and need is judged as normal condition.
2. sequence number 3, sequence number 8: after this two step interrupted, the main shaft cutter number equaled tool magazine cutter number, and the cutter on the cutter table number equals main shaft cutter number, but the tool magazine position not at initial position, under this state, tool changing stops the Z axle and moves and can cause tool magazine along bad.Be judged as fault, processing mode is normal condition for using the withdrawing program that tool magazine is shifted out the back
3. sequence number 4, sequence number 5, sequence number 6, sequence number 7:: after this four step interrupted, do not have cutter on the main shaft, just be not equal to tool magazine cutter number, the cutter on the cutter table number be the cutter number after the last normally tool changing, also is not equal to tool magazine cutter number.In this case, even use the withdrawing program to shift out tool magazine, the cutter that can't swap out next time and need.Be judged as random cutter state.
By on can know, after having analyzed whole exchanging knives process and having interrupted the situation that tool changing need handle,, can correct even can guarantee that whole tool changing interrupts also as long as handle second kind of tool magazine fault and the random cutter of the third tool magazine well.
This vertical machining centre umbrella shape tool magazine of the present invention is the control method of random cutter not, need to detect whether random cutter of tool changing last time, is confirmed that by random cutter mark whole new tool changing logic flow is seen Fig. 3, and concrete steps are following:
(1), according to general tool changing logic flow, each work step is interrupted different situations that the back occurs marks and process;
(1.1) if interrupted at the work step of " the Z axle moves to tool changing point position ", mark is normal;
(1.2) if interrupted at the work step of " warrant stop of spindle ", mark is normal;
(1.3) if interrupted at the work step of " the tool magazine shift-in is cutter also ", use the withdrawing program that tool magazine is shifted out after, be labeled as normal condition;
(1.4) if interrupted at the work step of " main shaft pine cutter ", the random cutter of mark, tool changing stops;
(1.5) if interrupted at the work step of " the Z axle moves to the tool changing ready position ", the random cutter of mark, tool changing stops;
(1.6) if interrupted at the work step of " tool magazine rotation seek target cutter number ", the random cutter of mark, tool changing stops;
(1.7) if the work step in " Z axle arrival tool changing point position " is interrupted, the random cutter of mark, tool changing stops;
(1.8), be labeled as normal condition after using the withdrawing program that tool magazine is shifted out if interrupted at the work step of " the tight cutter of main shaft also refreshes cutter table ";
(1.9) if interrupted at the work step of " tool magazine shifts out ", mark is normal;
(1.10) if interrupted at the work step of " warrant stop of spindle release ", mark is normal;
(2), the tool changing program begins, and reads whether random cutter mark is arranged;
(3) if there is not random cutter mark, then the Z axle moves to tool changing point position--warrant stop of spindle--the tool magazine shift-in is cutter also--main shaft pine cutter; If random cutter mark is arranged, then the Z axle moves to tool changing point position, and--the Z axle moves to the tool changing ready position, and--the Z axle moves to tool changing point position to tool magazine shift-in--tool magazine rotation seek former cutter number--;
(4), the Z axle moves to the tool changing ready position--target cutter number is sought in tool magazine rotation--the Z axle arrives tool changing point position--the tight cutter of main shaft and--tool magazine shifts out--warrant stop of spindle release-completion tool changing program that refreshes cutter table.
Tool magazine quits a program to be needed to handle two kinds of different situations, during fault 1, over against the no cutter of the cutter of main shaft, can earlier tool magazine be shifted out on the tool magazine; During random cutter, tool magazine has cutter on the cutter of main shaft number, and main shaft is loose cutter state, needs earlier main axle moving then tool magazine to be shifted out to the tool changing ready position.Whole withdrawing logic flow is seen Fig. 4;
(1), the withdrawing program begins, and reads whether random cutter mark is arranged;
(2) if random cutter mark is arranged, then the Z axle moves to the tool changing ready position, pauses 1.5 seconds, and tool magazine shifts out, and the withdrawing program is accomplished then;
(3) if there is not random cutter mark, then tool magazine shifts out, and pauses 1.5 seconds, and the Z axle moves to the tool changing ready position, and the withdrawing program is accomplished then.
Embodiment 1: Siemens 802S/C does not have address signal mutual between PLC and the NCK, therefore, is judging that whether the record tool magazine must can only handle in the realization of random cutter and new tool changing logic on PLC.802D has the interface IP address between PLC and the NCK, realizes but can use with a kind of method.
