When the automatic operation of lathe restarts after this automatic operation is interrupted midway, this generator 9 is arranged from the main cohort of main cohort storage unit 5 outputs according to the execution sequence of appointment, wherein this execution sequence is based on the data of the machining state of exporting from machining state storage unit 4, and the output signal when interrupting based on the machining state of output signal storage unit 6 outputs when interrupting is recovered order 8 thereby automatically produce machining state.The machining state that produces recovers order 8 and is output to NC device 1,1a, or have more terrain ground, be output to NC device 1, the program analyzer 7 of 1a.
Above-mentioned control method and control device 10 according to this lathe, 10a, when the automatic operation of lathe is had no progeny in midway when restarting according to the NC program command at this automatic operation, the operator need not manually to produce or correct machining state and recovers order 8 machining state is returned to the identical state of machining state when interrupting.
Further, automatic operation restarts from breakpoint P, has for example to have avoided during for example workpiece falls, the security of Physical Interference problem being arranged between workpiece and instrument during workpiece and instrument move.
According to present embodiment, will indicate the NC program command of the action of the machining state that changes lathe to be categorized into five main cohorts, it comprises the first to the 5th cohort.
Each main cohort comprises one or more subgroup groups.In each main cohort, be these one or more subgroup groups' distribution numbering separately.Therefore, with the Sequential output NC program command of the numbering of distributing to the subgroup group.
The first cohort comprises at least one the subgroup group who has be used to the NC program command of cancelling (retract) parts, described parts are for example for being used for the sensor of measuring workpieces, as not cancelling, these parts will become when the movable axle of lathe moves the obstacle to this shifting axle.
This is not cancelled the parts that will become obstacle and trends towards when movable axle moves this movable axle being caused Physical Interference, and therefore trends towards hindering when movable axle moves movable axle.This first cohort comprises be used to the NC program command of cancelling these parts.By these parts being left in given position these parts are cancelled.
Owing to cancel this by the M code in the first cohort and do not cancel the parts that will become obstacle, can avoid for example when movable axle moves, damaging the trouble that instrument and workpiece and workpiece drop.
The second cohort comprises at least one the subgroup group who has be used to the NC program command of clamping and decontrol movable axle.
The second cohort arranges the M code in a sub-cohort, be used for clamping and decontrol each movable axle, and the M code also is set in another subgroup group, is used for connecting and disconnecting movable axle.
The 3rd cohort comprises having the subgroup group who is not included in the NC program command in other main cohorts (the first cohort, the second cohort, the 4th cohort and the 5th cohort), and this order belongs to the required order of machining state that recovers this lathe.
Subgroup group in the 3rd cohort comprises, for example is used for opening the M code that grooving obtains the NC program command of screw thread circulation.

The 5th cohort comprises at least one subgroup group, and this subgroup group has for behind the internal state of determining lathe, the NC program command of making immediately action before automatic operation restarts.
The M code relevant with providing of refrigerant is provided the subgroup group of the 5th cohort.For example, the 5th cohort comprises the subgroup group who has for opening or close the M code that provides of refrigerant, and comprises the subgroup group for the M code of opening and closing air blast.
When by machine tool processing workpiece, wherein utilize control method and control device 10 according to lathe of the present invention, 10a automatically operates this lathe, main cohort comprise following one of at least: comprise at least one subgroup group the first cohort, comprise at least one subgroup group the second cohort, comprise described subgroup group the 3rd cohort, comprise at least one subgroup group's the 4th cohort and comprise at least one subgroup group's the 5th cohort.
When the automatic operation of lathe restarts after this automatic operation is interrupted midway, machining state recovers the execution sequence (sequence) that order generator 9 is determined the NC program commands, thereby will be from arranged sequentially according to the first cohort, the second cohort, the 3rd cohort, the 4th cohort and the 5th cohort of the main cohort of main cohort storage unit 5 outputs.Therefore machining state recovers to order generator 9 automatically to produce machining state and recovers order 8.
The M code in the first to the 5th cohort, generator 9 also adopts the T code that is used for selection tool, is used for selecting for example main spindle rotating speed and the isoparametric S code in position that restarts module.Generator 9 automatically produces machining state and recovers order 8, is used for recovering to have the module that restarts of the state identical with interrupt module.
According to above-mentioned control method and control device 10,10a, lathe operable automatically be in idle condition, lathe processing work not in this idle condition.In this case, main cohort comprises: comprise the first cohort of at least one subgroup group, this subgroup group has be used to the NC program command of cancelling parts, if the obstacle of this movable axle when these parts are not cancelled the movable axle that then will become lathe and moved; And the second cohort that comprises at least one subgroup group, this subgroup group has be used to the NC program command of clamping and decontrol movable axle.
In this case, when the automatic operation of lathe restarts after this automatic operation is interrupted midway, generator 9 is determined the execution sequence of NC program command, thereby with the main cohort from main cohort storage unit 5 outputs arranged sequentially of the first cohort and the second cohort, and this generator 9 automatically produces machining state recovery order 8.
For recovering machining state, do not need to count the M code of processed workpiece, so this M code does not belong to above-mentioned five main cohorts.Therefore, when recovering machining state, ignored the M code that is used for counting processed workpiece.
The control device 10a that Fig. 3 shows comprises that machining state recovers command generating device 2, and it is separately located in the outside of NC device 1a.Therefore, can be uniquely and freely design and modification and processing recovering state command generating device 2, and can not be subject to the design standards of NC device 1a and the restriction of configuration.
Fig. 2 and 3 control device 10 that show, the NC device 1 of 10a, 1a comprises respectively NC program actuator 20.
The NC program command 12 that is produced by program analyzer 7 also passes through 24 processing of PLC (programmable logic controller (PLC)) processor.The NC program command 12 of being processed by PLC processor 24 outputs to each servicing unit by I/O unit 22, comprises ATC (automated tool replacer, Automatic Tool Changer) 25, and workpiece measuring device 26.Therefore lathe automatically operates with processing work continuously.
30 storages of M code cohort storage unit are used for arranging the classification of main cohort, and the information that is used for arranging the subgroup group who is contained in main cohort.Being stored in M code cohort arranges information in the storage unit 30 and is outputed to respectively program analyzer 7 and machining state and recover order generator 9.
After output signal when output signal storage unit 6 has been stored the machining state interruption of being exported by program analyzer 7 when interrupting, the machining state when storage unit 6 will be interrupted outputs to machining state and recovers order generator 9.Storage unit 6 comprises NC internal state storage unit 31, M code cohort output state storage unit 32, tool state storage unit 33 and main spindle state storage unit 34.
NC internal state storage unit 31 storage NC devices 1, the coomand mode among the 1a.When the execution of NC program 3 in have no progeny when restarting, by from NC program 3 begin to interrupt module NC program 3 is scanned, obtain this coomand mode.
For example, the position of NC internal state storage unit 31 storage program modules (for example position of instrument cut edge), and the cooked mode of finishing constantly (before namely the next-door neighbour carries out and restarts module) at breakpoint P place interrupt module.
When breakpoint P finishes interrupt module, namely the next-door neighbour carries out heavily before the personal delivery dynamic model piece, M code cohort output state storage unit 32 each subgroup group's of storage final output M code.
Especially, when from NC program 3 begin to interrupt module scan N c program 3 time, among the storage unit 32 storage subgroup groups clamp and the relieving process in any one, for example clamp process, whether be in the done state of interrupt module, namely be in the initial state that restarts module.
By the M code in the scanning restart routine, with reference to being stored in the setting that M code cohort arranges the subgroup group in the storage unit 30, obtain the M code of final output simultaneously.
When the interruption module was finished, namely the next-door neighbour carried out and restarts before the module, and 33 storages of tool state storage unit are installed in the instrument on the main spindle, the instrument of namely selecting, and the instrument that is positioned at the spare space at this moment.By the output of scanning T code and the instrument replace command in the NC program 3, the state of the instrument that obtains to select and at the state of the instrument of spare space to restart.
When interrupt module was finished, namely the next-door neighbour carried out and restarts before the module, the 34 storage main spindle rotating speed orders of main spindle state storage unit.Output by the S code in the scan N c program 3 obtains the order of main spindle rotating speed to restart.The main spindle rotating speed order that obtains is stored in the main spindle state storage unit 34.
The below is with the control method of the flow chart description lathe among main reference Fig. 4.
According to NC program 3, by from NC device 1, the NC program command 12 of 1a output, lathe automatically operates in cooked mode with processing work.This lathe also can automatically operate in idle pulley, wherein lathe processing work not.
In step 101,, after the breakpoint P place of job sequence 3 is interrupted, can recovers order 8 based on the machining state that recovers command generating device 2 outputs from machining state and restart this automatic operation from breakpoint P at the automatic operation of lathe.
After the automatic operation of lathe was interrupted, wherein workpiece was processed, and machining state recovers command generating device 2 startup preparation processes in step 102, restarts this automatic operation.Then in step 103, at first export the instrument replace command.
If lathe is lathe or similar lathe, then the output T code that is used for the guiding tool dormancy and replaces instrument is as the instrument replace command.On the other hand, if lathe is machining center or multiaxis turning (turnning) center, then export the T code that is used for the instrument that wakes up and the instrument replace command M6 that is used for ATC25 as the instrument replace command.
After this, in step 104, M code cohort arranges storage unit 30 and exports the M code in the first cohort in five main cohorts to machining state recovery order generator 9.
Especially, M code cohort arranges the M code that is used for cancelling or storing all parts of the subgroup faciation pass that comprises in storage unit 30 outputs and the first cohort, and described parts are for example for being used for the sensor of measuring workpieces.
Therefore, in step 104, if cancel in advance the parts that all do not cancel the obstacle that will become movable axle, avoid when instrument and workpiece movable, they being carried out Physical Interference.
Then, in step 105, M code cohort arranges storage unit 30 the M code in the second cohort is outputed to machining state recovery order generator 9.
Especially, M code cohort arrange storage unit 30 its only according among the subgroup group who comprises in the second cohort corresponding to movable axle being moved to the subgroup group who restarts the position, output is used for decontroling the M code of movable axle.If be provided with for the M code that connects movable axle by parameter, after finishing for the order of decontroling movable axle, M code cohort arranges the M code that storage unit 30 outputs are used for connecting movable axle so.
So decontroled because move to the movable axle that restarts the position, this movable axle is movable to and restarts the position.
Then, be used for each movable axle is moved to each order of restarting the position in step 106 output.In step 106, be used for movable axle is moved to the order of restarting the position by any one generation in the first to the 3rd process described below.
(the first process)
Restarting the starting point of module, the position of the movable axle of the end point of the module when namely NC program 3 is interrupted is designated as the position of restarting that movable axle will move to.Can be by the order of selecting movable axle to move by the parameter of the manual input of operator.Can be safely mobile movable axle progressively, thereby make the operator can confirm the movement of movable axle.
If the operator observes visually, move to from current location at movable axle and to restart the process of position the danger that occurs with object generation Physical Interference, then can avoid this danger by process B1 described below or process B2.
(process B1): move in the process that restarts the position at movable axle, under vision is observed, movable axle is manually moved to the position of avoiding Physical Interference.
(process B2): move in the process that restarts the position at movable axle, before movable axle moves, set up the intermediate point of the Physical Interference of avoiding movable axle.Then, movable axle moves to through intermediate point from current location and restarts the position.
(the second process)
By scanning and storing mobile path after replacing with the instrument that will use, and by adopting the program command of the program module when from the current location to the automatic operation, restarting beginning, automatically produce movable axle is moved to the order of restarting the position.
(the 3rd process)
Acquire and restart till the module, and till the breakpoint P workpiece data of the three-dimensional model of processed workpiece (3D model), then the workpiece data of the 3D model by adopting the workpiece that obtains produces from current location to the movement directive that restarts the position.
In step 106, according in above-mentioned the first to the 3rd process any one, the order movable axle moves to and restarts the position.
Then, in step 107, M code cohort arranges storage unit 30 another M code in the second cohort is outputed to machining state recovery order generator 9.Especially, M code cohort arranges the M code that is used for clamping movable axle among the subgroup group among the subgroup group who comprises in storage unit 30 output the second cohort, and the final output of restarting in this subgroup group in the module represents to clamp state.
In step 105 and step 107, the relieving of each movable axle and clamp and can in the second cohort, restart.
Thus, nipped movable axle moves at movable axle and is jammed after restarting the position when interrupting, and the movable axle of having been decontroled when interrupting moves at movable axle and keeps decontroling after restarting the position.
Then, in step 108, M code cohort arranges storage unit 30 the M code in the 3rd cohort is outputed to machining state recovery order generator 9.Especially, M code cohort arranges the identical M code of final output in the interrupt module among the subgroup group who comprises in storage unit 30 output and the 3rd cohort.
Then, in step 109, M code cohort arranges storage unit 30 the M code in the 4th cohort is outputed to machining state recovery order generator 9, and main spindle state storage unit 34 outputs to machining state recovery order generator 9 with the S code in the 4th cohort.Especially, M code cohort arrange storage unit 30 will with the subgroup group that comprises in the 4th cohort in the identical M code of final output in the module that restarts output to machining state and recover order generator 9, and main spindle state storage unit 34 outputs to machining state with the S code that is used for order main spindle rotating speed among the subgroup group who comprises in the 4th cohort and recovers order generator 9.
If the M coded representation main spindle of output rotates order, then M code cohort arranges storage unit 30 outputs by the M code for the detent of closing mobile jib of parameter setting, and is used for the M code that cancellation C axle connects.Therefore in step 109, allow to restart the rotation of main spindle.
Then, in step 110, M code cohort arranges storage unit 30 the M code in the 5th cohort is outputed to machining state recovery order generator 9.Especially, M code cohort arranges the identical M code of final output in the interrupt module among the subgroup group who comprises in storage unit 30 output and the 5th cohort.
When execution in step 103 arrived the process of step 110, machining state recovered the 9 automatic generation machining states recovery orders 8 of order generator, and the machining state that will produce recovers to order 8 to output to program analyzer 7.
Recover the generation of order 8 when finished machining state in step 111, and when having finished other preliminary activities, in step 112, finish be used to the preparation process that restarts automatic operation.
After being used for restarting the preparation process of automatic operation, NC device 1, the remaining NC program output NC program command 12 that 1a begins based on the breakpoint P from NC program 3.Therefore the NC program command 12 of output is so that lathe can restart its automatic operation with processing work from breakpoint P.
As indicated above, machining state recovers order generator 9 and automatically produces machining state recovery order 8.Therefore when the automatic operation of lathe restarted after this automatic operation is interrupted midway, the operator need not manually to produce or correct machining state and recovers order 8.
The operator only need press the button, or input is used for restarting the order of automatic operation, and need not to carry out complicated processing.Lathe restarts its automatic operation, and continues continuously automated machining of workpieces.Therefore, the operator need not to possess very high technical ability.
Because it is automatically to produce that machining state recovers order 8, prevented that the operator from correcting the execution sequence of NC program command mistakenly.When the automatic operation of lathe restarts, prevent that the parts of lathe from undesirably being moved, and prevent with miscellaneous part and element Physical Interference being arranged, therefore can be not destroyed.
Control lathe according to the present invention with the method and apparatus that restarts its automatic operation applicable to lathe, machining center, multiaxis turning center and lathe.
Although describe in detail and shown some preferred embodiment of the present invention and modification, should understand and the invention is not restricted to described embodiment and modification, can it is made variations and modifications and can not exceed the scope of claims.
