Sheet plates
The aim of the test. Plates warp when laser machining. Wants to prevent the laser delay vibrate multi directional with the new MEMV. It works better than expected.
Test 1 XY1, 05/03/2018 09:00 09:10:15
Part name: metal sheet Component weight: 540 kg Dimension: 15x3000x1500 Material: S420MC Number / Component: 1 Zone excitation X: 83.6 Zone excitation y: 27.5 Zone excitation Z: 58.7 Stimulated: D1 / D2 / D3 8/8/8 '
1 pcs. plate 10mm 2000 x 3000 Material Weight: Problem: warps the laser machining of various components.. Vibration relaxed: 3 x 8 minutes in the direction D1, D2, D3
Figure 2: Test XY1 attachment of the exciter. There was the noise level to over 90db. Thinner nuts would have fixed the problem.
Figure 3: This slide in the photo are crooked in untreated MEMV plates in mm enriches. All the plates, the plates being treated from the MEMV were cut were straight, no light gap visible to the ruler.

Test XY 23, 6.3.19 11:15 to 13:15
Part name: metal sheet Component weight: 2500 kg Dimension: 10x2500x1250 Material: DD12 Number / components: 10 Zone 1 2 Zone displacement X 56.9 / 73.8 m/ s2 Zone displacement Y: 184/185 m/ s2 Zone displacement Z: 29 / 10.8 m/ s2 Stimulated axis / min: D1 / D2 place 1 8/8 ' D3 place 2 15` New second test with the plates 10 pcs. plates 6 mm 2000 x 3000 Material Weight: MEMV stimulated with D1, D2, D3 and re-clamping. test dead center shift assay also rubber redistribution
Vibration relaxed: 3 x 8 min. minutes towards clamping point 1 Vibration relaxed: 2 x 8 min. minutes towards clamping point 2

Figure 36: The dead center axis directions was in div determined and created a new definition.. Due to further investigations and studies the issue will not be discussed further.
Figure 37:
Result: XY 23, 80% of the plate, the parts were straight. 20% not ok Action: are controlled by the software and the machine dead center shift has yet, then all zones are reached.
