00:00:00.540 --> 00:00:01.720
My name is Edmund Jenner.

2
00:00:01.720 --> 00:00:04.080
I am the managing director of Nordfels GmbH.

3
00:00:04.940 --> 00:00:07.400
Nordfels GmbH is based in Upper Austria,

4
00:00:07.400 --> 00:00:10.340
in the north of Austria.

5
00:00:10.680 --> 00:00:13.280
We manufacture special-purpose machines

6
00:00:13.280 --> 00:00:16.280
for our customers, who are

7
00:00:16.280 --> 00:00:18.280
usually manufacturing companies.

8
00:00:19.220 --> 00:00:20.640
This application involves

9
00:00:20.640 --> 00:00:22.940
the high-precision measurement

10
00:00:22.940 --> 00:00:25.100
of aluminum components,

11
00:00:26.400 --> 00:00:29.040
which we had to carry out

12
00:00:29.040 --> 00:00:31.080
in the customer’s production environment.

13
00:00:32.220 --> 00:00:33.640
Dust,

14
00:00:33.640 --> 00:00:35.420
temperature fluctuations

15
00:00:35.420 --> 00:00:37.420
and vibrations can occur there.

16
00:00:38.340 --> 00:00:40.560
Using the MLWL profile sensors,

17
00:00:40.560 --> 00:00:43.820
we were able to record a 3D point cloud,

18
00:00:43.820 --> 00:00:45.240
a digital twin of the entire

19
00:00:45.240 --> 00:00:47.240
test object, and then measure

20
00:00:47.960 --> 00:00:49.700
all measurement points

21
00:00:49.700 --> 00:00:52.400
in this point cloud

22
00:00:52.400 --> 00:00:54.480
according to customer requirements.

23
00:00:55.860 --> 00:00:57.060
To achieve the high accuracy

24
00:00:57.060 --> 00:00:59.240
of the digital twin,

25
00:00:59.240 --> 00:01:01.000
we use a patented solution in which

26
00:01:01.000 --> 00:01:06.000
we scan reference objects with the

27
00:01:06.000 --> 00:01:08.000
test object and then use these

28
00:01:08.000 --> 00:01:11.000
mathematically known reference objects

29
00:01:11.000 --> 00:01:14.000
to correct the test object.

30
00:01:14.000 --> 00:01:17.000
We chose wenglor’s MLWL

31
00:01:17.000 --> 00:01:19.000
profile sensors because their

32
00:01:19.000 --> 00:01:22.000
large format gives them

33
00:01:22.000 --> 00:01:25.000
a relatively flat triangulation angle,

34
00:01:26.000 --> 00:01:29.000
which is important for high accuracy.

35
00:01:29.000 --> 00:01:30.000
And because the sensors

36
00:01:30.000 --> 00:01:33.000
are very robust devices,

37
00:01:33.000 --> 00:01:35.000
so that they can be used

38
00:01:35.000 --> 00:01:36.000
in the middle of the production environment.
