(manufacturing procedure)
Fig. 3 is the figure of expression work flow.Handling part 50 instruction supporters 10 move (S11) from the position as starting point to the XY desired value.By this instruction, drive first dirver (XY drive division 16,18), supporter 10 (XY worktable 12,14) moves.During supporter 10 moved, analyzer (XY sensor 32,34) was measured the position of supporter 10.For example measured with per 0.1 second.Mensuration only is not limited to during the position of determining supporter 10, determines in the position that also the back carries out in the processing of workpiece 1, also can carry out after the processing of workpiece 1.At least the determination data (XY measured value) that obtains in workpiece 1 descends can be used in the detecting method for processing result described later.
Afterwards, handling part 50 (exclusive disjunction portion 52) judges whether supporter 10 arrives XY desired value (S12).Particularly, relatively X measured value and X desired value compare Y measured value and Y desired value.Step S12 arrives the XY desired value up to supporter 10 repeatedly.When supporter 10 arrived the XY desired value, the position of workpiece 1 (supporter 10) was determined, and advances to step S13.
In step S13, handling part 50 (exclusive disjunction portion 52) appointment instrument 20 moves (decline) to the Z desired value.By this instruction, drive second driver (Z drive division 22), instrument 20 moves.Fig. 4 (A)-Fig. 4 (C) is the figure of specification tool 20 actions.Shown in Fig. 4 (A), the instrument 20 that is in start position moves (decline) shown in Fig. 4 (B).During instrument 20 moves, the position of analyzer (Z sensor 36) tools for measurement 20.For example measured with per 0.1 second.(in the processing), processing back (instrument 20 connects workpiece 1 back) are measured before instrument 20 contact workpieces 1, in the contact.At least the determination data (Z measured value) that (in the processing) obtains during instrument 20 contact workpieces 1 is used for detecting method for processing result described later.
Afterwards, handling part 50 (exclusive disjunction portion 52) judges whether instrument 20 arrives Z desired value (S14).Particularly, compare Z measured value and Z desired value.
Step S14 arrives the Z desired value up to instrument 20 repeatedly.Shown in Fig. 4 (C), when instrument 20 arrives the Z desired value, become processing work 1, advance to step S15.That is, handling part instructs instrument 20 to move (rising) along the direction of leaving the Z desired value.By this instruction, drive second driver (Z drive division 22), instrument 20 moves.By above operation, but processing work 1.
(detection method of processing result)
In the present embodiment, can detect the processing result of workpiece 1.Fig. 5 is the figure of the detection method of explanation processing result.In the detection of processing result, tool using 20 (is punching, is cutting, is grinding during cutting etc.) determination data (XYZ measured value) that obtains behind instrument 20 contact workpieces 1 during the processing work 1 at least.If the detection difficult of processing zero hour then also can be used before processing beginning the determination data that obtains after the process finishing.
For example, shown in Fig. 4 (B), handling part 50 (for example operational part 52) judges whether arrive first reference value (S21 shown in Figure 5) after instrument 20 moves.Particularly, compare Z measured value and first reference value.First reference value is the value of storing in advance as the reference data storage part 48 of the position of the instrument 20 of (before the processing) before instrument 20 contact workpieces 1.Repeating step S21 reaches first reference value up to instrument 20.After instrument 20 reaches first reference value, the storage (S22) of beginning XYZ measured value.Afterwards, process, after the process finishing, shown in Fig. 4 (C), instrument 20 moves to the direction that departs from the Z desired value.
Shown in Fig. 4 (B), handling part 50 (for example operational part 52) judges whether arrive second a reference value (S23 shown in Figure 5) after instrument 20 moves.Particularly, compare the Z measured value and second a reference value.Second a reference value is the value of storing in advance as the reference data storage part 48 of the position of the instrument after the process finishing 20.In the present embodiment, because instrument moves back and forth, so first, second a reference value can be a same position.In addition, as displacement, both also can be different.Repeating step S23 reaches second a reference value up to instrument 20.After instrument 20 reaches second a reference value, finish the storage (S24) of XYZ measured value.
Therefore, obtain determination data (XYZ measured value) during the instrument 20 actual processing works 1 at least.Particularly, the XYZ measured value that obtains in a plurality of chronometries.Handling part 50 (for example operational part 52) uses these measured values to judge whether processing normally carries out (S25).
Fig. 6 is the figure that an example of the flow process whether processing is normally carried out is judged in explanation.For example, judge whether X setting (lower limit)≤X measured value≤X setting (upper limit) (S31, S32), judge whether Y setting (lower limit)≤Y measured value≤Y setting (upper limit) (S33, S34).Carry out these judgements by operational part 52.If satisfy above condition, mean that then in the processing of workpiece 1, supporter 10 is in the appropriate location.
In addition, judge whether instrument 20 suitably moves.For example, the lower dead center of checking tool 20 (maximum shift position).For example, from the Z measured value, extract mobile maximum (position of lower dead center) (S35), judge whether mobile maximum 〉=Z setting (S36).Arrive the Z desired value because detected instrument 20, so needn't change the inspection of minimum shift position.Operational part 52 carries out these judgements.If satisfy above-mentioned condition, mean that then instrument 20 suitably moves (moving to the appropriate location).
Judge according to these, can carry out the whether qualified judgement of processing result of workpiece 1.
If qualified, then carry out the processing (S26) of OK correspondence.For example, in efferent 56 (with reference to Fig. 2), show OK.If defective, then carry out the processing (S27) of NG correspondence.For example, the limit shows NG at efferent 56 (with reference to Fig. 2), and the limit is arresting stop in order to stop processing.
At least preserve the data (S28) whether processing result uses in the qualification determination.For example, in auxiliary storage portion 49, preserve data.These data can be used for understanding the performance or the machining accuracy of device.
According to the detection method of the processing unit (plant) or the processing result of present embodiment, can after the process finishing of workpiece 1, needn't just check once more and can detect this processing result.
[embodiment]
Fig. 7-Figure 10 is the figure that the instantiation of the detection method that is suitable for processing result of the present invention is described.Here, use above-mentioned processing unit (plant).Transverse axis is represented elapsed time, and the longitudinal axis in left side is represented the displacement (XY measured value) of XY worktable 12,14 (supporter 10), the displacement of the longitudinal axis representational tool 20 on right side (Z measured value).The XY measured value is relative value (displacement), and the Z measured value is absolute value (position).
In example shown in Figure 7, XY worktable 12,14 repeats to move to the XY desired value from starting point, by the XY desired value, passes through the XY desired value once more after oppositely advancing, and slowly converges near the XY desired value.Instrument 20 begins to descend when XY worktable 12,14 both sides arrive the moment (time t1) of XY desired value, rises after stopping after arriving the Z desired value again.Instrument 20 arrives first reference value when t2, arrive second a reference value when t3, so carry out the storage of XYZ measured value between t2-t3.Through behind the t3, judge whether processing is normal.As a result, the XY measured value between the t2-t3 is between XY setting (lower limit)-XY setting (upper limit).In addition, though the Z measured value surpasses the Z desired value, do not surpass the Z setting.Therefore, judge that processing result is qualified, carry out to the processing of correspondence.
In example shown in Figure 8, XY worktable 12,14 moves to the XY desired value from starting point, after the XY desired value, does not converge near the XY desired value.The action of instrument 20 is identical with example shown in Figure 7.In this example, the XY measured value between the t2-t3 is in the outside of XY setting (lower limit)-XY setting (upper limit).Therefore, judge that processing result is defective, carry out to the processing of correspondence.
In example shown in Figure 9, the action of XY worktable 12,14 is identical with example shown in Figure 7.Z measured value between the t2-t3 surpasses the Z setting.Because instrument 20 too descends, therefore, judge that processing result is defective, carry out to the processing of correspondence.
In example shown in Figure 10 because the XYZ measured value is in arbitrary processing result all in the acceptable ranges, therefore, carry out to the processing of correspondence.But the Y measured value does not converge near the Y desired value.Preserve this data, can apply flexibly in the maintenance etc.
