Embodiment
(1), the implementation method of parametrization design:
Utilize the inventive method when software design; Respectively with tool magazine type, the number of axle select for use, cutter holder quantity selects or the like many control function to be programmed in the ladder diagram as an independently opening module; Use self-defining correlation parameter position again, as the soft switch of opening and closing selected function, like this; To product, as long as just passable with a kind of PMC Control Software with a series of even whole company.And be column and knee type or lathe bed formula for lathe; Be general NC lathe or machining center; Work in-process is to adopt the umbrella shape tool magazine or the Different control function of different model lathes such as mechanical arm tool magazine and tool magazine capacity in the heart, selects just to be provided with and can accomplish as long as press actual needs through a detailed function control table.How be one below simply utilizes the built-in PMC platform of FANUC to carry out secondary development; To the instance that parametrization design control is carried out in the start and stop of cooling motor, this control method can both can adopt the method for conventional establishment part program to carry out to the opening and closing of liquid coolant through the setting of custom parameter position; Also can realize when not having the rotate command of main shaft; Liquid coolant stops automatically, and the automatically actuated function in main axis rotation order back is arranged, and its PMC program is as shown in Figure 2.
The definition of the contact signal relevant with this function and function are following among Fig. 2:
R560.3 stops M signal from the selection that NC comes:
R600.0 is that main shaft is just changeing M signal:
R600.1 is a main shaft counter-rotating M signal:
R600.5 is M08 (liquid coolant starting) M signal that comes from NC:
R600.6 is M09 (liquid coolant stops) M signal that comes from NC:
R635.7 is a lathe automated manner M signal:
R660.4 is that liquid coolant is suspended M signal:
R660.7 is that the cooling starting keeps M signal:
G8.4 is the emergent stop signal that PMC outputs to the NC side:
Fl.1 is the reset signal that NC is input to PMC:
Y2.0 is the cooling motor initiating signal that PMC outputs to the lathe side;
K13.2 is that the type of cooling is controlled soft switch:
The practical implementation step is following:
As shown in Figure 2, during original state, Y2.0; R660.4, R660.7 are " 0 ", and suddenly stopping G8.4 is l; If select the function of liquid coolant for use with the main shaft start and stop, only need parameter K 13.2 is made as " l ", automated manner is down when there is the M8 order in system; (liquid coolant starts R600.5 and becomes " 1 " M08, and corresponding M08 holding signal R660.7 becomes " 1 " and self-locking.When main shaft just changes (R600.O) and counter-rotating (R600.1) signal when all being " O " (main shaft is rotation not), liquid coolant halt signal R660.4 is by set, makes the output (Y2.0) of liquid coolant be " 0 ", no liquid coolant outflow this moment.When the arbitrary signal of forward or reverse became " l ", promptly during main axis rotation, R660.4 was reset to " O ", and set has realized that liquid coolant flows out to liquid coolant output signal Y2.0 in main axis rotation through the maintenance effect of R660.7.
In like manner, cool off when signal is effective and also follow action, parameter K 12.1 then can be set be " 1 " if select to stop (M01), when stop signal is selected in NC output (R560.3), through the output of R660.4 control Y2.0, realization parameter control function.
(2), the method for designing embodiment of fault demonstration:
In practical application, often, show a plurality of failure messages simultaneously because the appearance of a fault can cause the chain reaction of other dependent failure, as long as and in fact got rid of the most original failure cause, other fault also will disappear.
But in the failure message that shows, the maintainer does not also know which is the immediate cause that causes fault, can only search one by one, not only loses time but also increased the maintenance difficulty usually.To this problem; The present invention has designed a large amount of fault alarm measuring abilities and disposal route directiveness text function or the like in this cover PMC Control Software; The trapezoid figure program of Fig. 3 is the reason that a system can judge primary fault automatically, and the example of display alarm number and content thereof, in the maintenance; As long as number get rid of these faults according to the warning of screen display, other initiating failure will be died away.
R680.1, R680.2 are the distributors that detects tool changing and air pressure failures, and R680.3, R680.4 and R680.5 are the zone bits that fault shows, are used for triggering the fault display message of tool changing, air pressure and feed shaft.The manipulator behavior of tool changing realizes that by tool arm motor and solenoid valve the Z axle can at first move to preposition during tool changing.If occur air pressure failures in the exchanging knives process, for preventing the generation of mishap, program can stop the tool changing action with the protection lathe.By in the past design, can show that cutter does not put in place this moment simultaneously, baric systerm fault and feeding block three failure messages.Program above we have designed will only show this warning message of air pressure failures in this case.Its principle of work is: during non-fault, three fault show label positions all are 0, because system is a sequential scanning PMC program; When air pressure failures took place, in first cycle of program scanning, fault detecting point R680.2 became " l "; Make R680.6 be changed to " 1 "; Fault shows that position R680.4 becomes " 1 " and self-locking like this, and R680.4 can trigger demonstration " air pressure failures ", is excluded (R680.6 becomes " 0 " automatically) up to fault; System reset (Fl.l is " l ") back R680.4 just is reset to 0, and warning message disappears.Because the R680.4 set also keeps; Realized blockade to R680.7, R680.3 and R680.5; Even fault detect this moment position R680.1 is " 1 ", the zone bit R680.3 that its fault is shown becomes " 1 ", and corresponding so with it failure message just can not show.Through the control of such PMC program, just can automatically in a plurality of similar fault that takes place in succession, judge primary fault and also show, thereby shorten the unnecessary repair time.
As shown in Figure 4, R800.0 is the interposition of umbrella shape tool magazine passage among the figure, and its dozens of soft contact is distributed in the whole software ladder figure statement relevant with the umbrella shape tool magazine; R800.1 is the interposition of hand type tool magazine passage, and its dozens of soft contact is distributed in the whole software ladder figure statement relevant with the hand type tool magazine; R800.2 is the interposition of four control lathe passages, and its dozens of soft contact is distributed in whole software and controls in the relevant ladder figure statement with four.
Among the present invention, with the soft switch of K7.6 as machine tool and machining center selection, when K7.6 is 0, close tool magazine software passage, lathe is a machine tool; When K7.6 is 1, open tool magazine software passage, lathe is a machining center.
Simultaneously, with the soft switch of K7.2, when K7.2 is 0, open umbrella shape tool magazine software passage as umbrella shape tool magazine and the selection of mechanical arm tool magazine; When K7.2 is 1, open mechanical arm tool magazine software passage.In addition, K8.5 when K8.5 is O, is three control lathes as three and four soft switches that lathe is changed mutually, when K8.5 is 1,, open the various function passages of four controls, lathe is four control lathes.Among the present invention, similar above-mentioned function is controlled soft switch and all is provided with one by one as required with similar said method, and just conversion goes out the numerically-controlled machine and the machining center of various functions easily.
