Running program V80 can have following all functions in principle, for example introduces in German patent application DE 10 2,005 045 028 A1.
So this German patent application of full content reference.
For can with true lathe 10 on the simulation on virtual lathe V10, implemented workpiece WS processing by the job sequence bag of making 78 for this reason in an identical manner under the identical as far as possible condition by virtual manufacture virtual workpiece VWS, in the program limit V132 of core control program V38, be provided with and be applicable to the parameter region V130 that receives core controlled variable 134.
At this, core controlled variable 134 can be the same parameter of using on the true lathe 10 of core controlled variable.
Under any circumstance, core controlled variable 134 includes the configuration parameter of model specific, for example as general parameters 136, because these parameters are special-purpose to the lathe 10 of single type.
In individual other configuration parameter, the configuration parameter that preferably also exists all to dynamically associate in the parameter region V130, special-purpose parameter 142 and the CNC functional parameter 154 of axle particularly is because these parameters are for very important in the processing speed of NC data set when simulating processing work WS by job sequence bag 78 processing virtual workpiece VWS.
Preferably include all configuration parameters that exist in the parameter region 130 of true lathe 10 in the parameter region V130 of virtual lathe V10.
In addition, can be additional function control program V58 allocation of parameters district V160 equally, parameter region V160 is applicable to and receives the additional function parameter that adopts 162 marks.
The additional function parameter 162 of all model specific for example all is present in the parameter region V160 as axle parameter 166 or interrupt parameters 170.
If when simulation job sequence bag 78, also need to consider in the lump additional function and therefore simulate additional function in the lump, need also to exist in the parameter region V160 other configuration parameter so equally, for example as Spindle Name parameter 188, so as can on the virtual lathe V10 with true lathe 10 on identical mode handle additional function.
At last, running program V80 also is provided with parameter region V180, can store in the parameter region V180 to be used for operating parameter 182 that running program V80 is cooperated with separately virtual lathe V10.
For the operator for simulation job sequence bag 78 realizes same operational circumstances, therefore preferably be set to: the configuration parameter to the model specific of major general's real machine bed 10 from operating parameter 182 is transferred in the parameter region V180 of virtual lathe V10.Be more preferably, also pass on other configuration parameter.
For this reason, the configuration feature V116 of running program V80 is equipped with configuration feature parameter receiver module V124, configuration feature parameter receiver module V124 can read from the external data carrier V202 of external data storage device V200 in the individual configuration parameter 142,154,168,188 of distributing to the true lathe 10 of complete special use and the parameter region 130,160,180 that writes virtual lathe V10 from the data storage device V200 of outside for example before beginning for the first time simulation.Therefore from the virtual lathe V10 of for example model specific configuration, generate the main at least configuration parameter of the virtual lathe V10 that matches with each other real machine bed 10.
Pack in the data storage device V200 as data carrier V202 if will distribute to the data carrier 202 of the data storage device 200 of true lathe 10, the configuration parameter that exists on the so true lathe 10 can be transferred on the virtual lathe V10 simply.
Another kind of possibility is that data storage device 200 arrives the interface of data storage device V200 with the data carrier 202 of true lathe by data transmission coupling arrangement (for example data line) and is connected with operating control device V70.
If should guarantee the absolute consistance of configuration parameter, configuration parameter receiver module V124 writes all configuration parameters that exist in the memory storage V200 in the parameter region 130,160,180 so.
For add by job sequence bag 78 simulation virtual workpiece VWS man-hour as on true lathe 10 like that with accurate same all processes of time synchronized operation, for core control program V38 distributes virtual chronotron, it comprises the interpolation pulse transmitter 262 that is used to produce virtual interpolation pulse VIT, and distribute time detecting unit 264, the virtual recurrent interval that is used for producing by virtual interpolation pulse is scaled and at interval and therefore virtual time VT is scaled RT actual time actual time.
Actual time, RT for example exported in the V100 of the viewing area of running program V80 by running program V80.
The interpolation pulse transmitter 262 of virtual chronotron 260 can generate virtual interpolation pulse VIT, and wherein, the recurrent interval is different from the recurrent interval of true interpolation pulse IT, for example obvious interval greater than true interpolation pulse IT.
Because in dummy activity control device V30, the processing of NC data set and the interpolation of each intermediate value are carried out based on virtual interpolation pulse VIT ground, so all temporal processes of dummy activity control device V30 and then also have the action of virtual processing unit V14 to change in time with identical degree prolong or shorten such as the interval with respect to true interpolation pulse IT, the interval of virtual interpolation pulse VIT.
If at this moment virtual lathe V10 utilizes the processing of machine control unit V20 by job sequence bag 78 simulation virtual workpiece VWS, simulation can for example be carried out in time based on the virtual interpolation pulse VIT of interpolation pulse transmitter 262 with delaying so, so that for the operator provides possible collision of accurate inspection or approximate possibility of collision, wherein, according to the indivedual cooperations of virtual interpolation pulse and lathe model 240 and the reception of individual configuration parameter, machining cell V14 accurately moves relative to one another as in the truth basically in real time when carrying out this inspection.
In addition, the possibility that time detecting level 264 also realizes is, non-ly from virtual time VT directly know RT actual time indirectly, thereby in the man-hour that adds by CNC job sequence bag simulation virtual workpiece VWS, not only can know the collision of machining cell V14, and can know be used for data set working time that the CNC data set handles or even every man-hour of workpiece VWS separately, every man-hour is according to virtual time VT is converted into RT actual time, and corresponding to the data set working time of processing every man-hour of true workpiece WS on true lathe 10, thereby virtual lathe V10 just can provide data set working time or every man-hour and therefore optimize every man-hour when simulation CNC job sequence bag 78.
Aspect the formation of cutter modeling 250, with not being elaborated as yet relatively to foundation solution of the present invention introduction up till now.
Therefore, first embodiment with advantage of the cutter modeling 250 shown in Fig. 7 is set to, this cutter modeling 250 has cutter model 270, stores the 3 dimensional coil geometry data of part in cutter model 270, can constitute virtual cutter VWZ by this geometry data.
Cutter modeling 250 comprises cutter data V280 in addition, cutter data V280 comprises the information of virtual cutter VWZ physical size, wherein, these physical sizes of virtual cutter VWZ are indispensable and as long as cutter data V280 and CNC job sequence bag 78 are stored in jointly in its set storer V76 for processing virtual workpiece WS, then when handling the CNC data set, consider in the lump by core control program V38.
Cutter modeling 250 comprises cutter configuration data maker 290 in addition, cutter configuration data maker 290 is by cutter model 270 and cutter data V280 configuration cutter configuration data 292, send cutter configuration data 292 to visualization procedure 238, so that this visualization procedure 238 and virtual lathe V10 will pack into corresponding to the virtual cutter VWZ of cutter data V280 configuration explicitly in each tool position of virtual processing unit V14.
This virtual cutter VWZ illustrates in Fig. 8 example of passing the imperial examinations at the provincial level, and wherein, virtual cutter VWZ is so-called 3 dimensional coil geometry model.
This virtual cutter VWZ comprises the knife rest also that can discern by the cutter identiflication number, that pass through 302 formation of knife rest main body that integral body employing 300 marks, this knife rest main body 302 for example has handle of a knife 304, and the cutter that knife rest main body 302 utilizes handle of a knife 304 to be fixed on machining cell V14 holds in the place.
Knife rest main body 302 has composition surface 306 in addition, utilizes this composition surface 306 this knife rest main body 302 can be installed on the supporting surface of machining cell V14, and described machining cell V14 is cutter capstan head or other types knife rest for example.
At this, keeper 304 and knife rest main body 302 are mutually permanently connected and form a unit that is associated.
Integral body can be adopted the handle of a knifes of 308 marks to pack in the knife rest main body 302, wherein, handle of a knife 308 can be assemblied in holding in the place 310 of knife rest main body 302 with respect to knife rest main body 302 on diverse location.
Handle of a knife 308 carries cutting members 312 (for example blade), and the blade 314 of cutting members 312 is used for cut.
For make virtual cutter VWZ by core control program V38 in company with knife rest 300 location and motion, basically two of blade 314 sizes play a decisive role, i.e. length value L 1 that the position of blade 314 on composition surface 306 described and length value L 2 that blade 314 is described with respect to the position of axle 316, this 316 distributes perpendicular to composition surface 306 and in the mode of passing keeper 304 between two parties.
The corresponding cutters of machining cell V14 holds the position in the place as long as also additionally definite knife rest 302 is packed into, then by this two length value L 1 and L2, has for example determined its position spatially for blade 314.
Under Fig. 8 and the exemplary knife rest that illustrates 300 situations of Fig. 9, in the cutter model, there are the 3 dimensional coil geometry data of knife rest main body 302 together with composition surface 304 3 dimensional coil geometry data and handle of a knife 308 and cutting members 312.
In addition, length value L 1 and L2 are corresponding to cutter data V280, cutter configuration data maker 290 is formed by the 3 dimensional coil geometry data of knife rest main body 302, handle of a knife 308, cutting members 312, and 292 of the cutter configuration datas of virtual cutter VWZ that are sent to visualization procedure 238 then are corresponding to length value L 1 and L2.
Be the cutter configuration data 292 that effectively to arrange to generate like this, operating control device 180 is equipped with tool function V118, the possibility that tool function V118 provides in cutter data input module V322 is, directly by predesignating cutter data V280 to the data input of cutter modeling 250 and having generation cutter configuration data 292 in the cutter generation module 324 of cutter configuration data maker 290 then, so that can be by visualization procedure 238 display of visually cutter VWZ on the display screen 212 of visualization 210.
But except in the cutter data input module V322 of running program V80, manually importing by machine tools control panel V90, also the possibility of Cun Zaiing is, in cutter data transmission module V326, arrangement receives cutter data 280 from storer V76, and cutter data 280 are stored in this storer 76 jointly and from this storer 76 cutter data 280 are offered core control program V38 with CNC job sequence bag 78 and process to utilize CNC job sequence bag 78.
Be configured with cutter WZ on true lathe 10 and measured under the situation of measuring position the operator, cutter data 280 ability that store that are associated down with job sequence bag 78 are distributed to corresponding C NC job sequence bag 78 then corresponding to real tool data 280 and these cutter data 280 in storer 76.
The structure of real tool WZ and measurement are in most of the cases directly being carried out before the true workpiece WS of processing on the true lathe 10.For this reason, the cutter data 280 of real tool were also directly being known before processing work WS on the measuring position and are being utilized the cutter data input module 322 of the tool function 118 of running program 80 to be stored in the storer 76 in the mode of distributing to job sequence bag 78.
If at this moment directly implemented the simulation to job sequence bag 78 once more on virtual lathe V10 before the true workpiece WS of processing, real tool data 280 also are transferred in the storer V76 so.
In order to realize: when simulation processing virtual workpiece VWS, real tool data 280 not only with true lathe 10 on identical mode by core control program V38 by with respect to, and when generating cutter configuration data 292, cutter data transmission module V326 realizes real tool data 280 are sent in the cutter modeling 250 from storer V76, thereby real tool data 280 are present in this system and are used to generate cutter configuration data 292.That is to say that the input of real tool data 280 in cutter modeling 250 carried out and can be directly used in generating cutter configuration data 292 in the approach that real tool data 280 is carried out Data Receiving from storer V76.
To this alternatively, giving following possibility according among first embodiment of cutter modeling 250 of the present invention, in the cutter data generation module V328 of tool function 118, at first based on the 3 dimensional coil geometry data of cutter model, diagram gives expression to each component of knife rest 300, knife rest main body 302 for example just, keeper 304, handle of a knife 308 and cutting members 312, for example also locate toward each other, thereby only pass through tool setting frame body 302 manually at the enterprising line display of the viewing area of machine tools control panel V90 V100, handle of a knife 308 and cutting members 312 relative positionings and generate virtual cutter VWZ.
But because the operator that each component diagram is located does not toward each other understand the cutter data of this virtual cutter VWZ, thus the cutter data also do not had for virtual cutter VWZ, thus will need this virtual cutter VWZ of detailed measurements.
This point is dispensable under the situation of using cutter data generation module 328, this cutter data generation module 328 is according to the position of cutter 300 each components, and just the relative position of knife rest main body 302, handle of a knife 308 and cutting members 312 is known cutter data V280 and is stored in the cutter modeling 250.
Cutter data V280 in the cutter modeling 250 also can utilize cutter data transmission module V326 to send storer V76 to and distribute to CNC job sequence bag 78 from cutter modeling 250 then, thereby core control program V38 utilizes 280 work of cutter data when implementing simulation, and these cutter data 280 utilize cutter data generation module 328 to generate by cutter modeling 250 and the control of therefore each action is also carried out under the situation of considering this virtual cutter data V280.
Foundation shown in Figure 12 cutter modeling 250 of the present invention ' another embodiment in, cutter model 270 ' the do not comprise accurate geometry data of each component that is used for constructing virtual cutter VWZ, but comprise geometric configuration volume body, therefrom can choose each individually long-pending body and import its size by the operator.
Therefore, under the situation of using cutter data V280, cutter configuration data maker 290 is not to generate and the essentially identical cutter configuration data 292 of real tool, but generate the cutter configuration data 292 draw virtual cutter VWZ ' ', this virtual cutter VWZ ' is aspect the cutter data, particularly length value L 1 and L2 aspect are very accurate, but the knife rest main body 302 of virtual cutter VWZ ' ' and handle of a knife 308 ' can with the truth of reality under significantly different.
Yet utilize this cutter modeling 250 ' but can show on the display screen 212 of visualization 210 situation of approximate correct spatial geometric shape at least, the situation of this spatial geometric shape is applicable to checks collision.
At this, cutter data V280 in this embodiment also can be according to importing with the identical approach of situation that first embodiment introduces relatively.
