1
00:00:01.533 --> 00:00:04.233
To build everything 

2
00:00:04.233 --> 00:00:05.666
workshops and factories around

3
00:00:05.666 --> 00:00:07.066
the country rely on the handiwork of

4
00:00:07.066 --> 00:00:09.532
machinists, and tool and die makers.

5
00:00:09.533 --> 00:00:11.266
Starting from blueprints, sketches,

6
00:00:11.266 --> 00:00:13.632
or computer-aided design files, they set up

7
00:00:13.633 --> 00:00:15.366
the machines that produce parts.

8
00:00:15.366 --> 00:00:16.532
Once products are made,

9
00:00:16.533 --> 00:00:17.733
they file and grind them to

10
00:00:17.733 --> 00:00:19.099
meet project specifications,

11
00:00:19.100 --> 00:00:22.266
giving them a final smoothing and polish to finish.

12
00:00:22.266 --> 00:00:24.566
Machinists run computer numerically controlled

13
00:00:24.566 --> 00:00:26.532
or CNC—machines…

14
00:00:26.533 --> 00:00:29.099
that produce precision metal parts and tools.

15
00:00:29.100 --> 00:00:31.766
They may produce a large number of one part–

16
00:00:31.766 --> 00:00:33.566
such as automobile pistons…

17
00:00:33.566 --> 00:00:34.966
or many small batches—

18
00:00:34.966 --> 00:00:37.199
like bone screws for medical implants…

19
00:00:37.200 --> 00:00:38.933
or even one-of-a-kind items.

20
00:00:38.933 --> 00:00:39.699
They need to be skilled with a

21
00:00:39.700 --> 00:00:42.566
wide range of machines and techniques.

22
00:00:42.566 --> 00:00:44.632
Toolmakers craft precision tools

23
00:00:44.633 --> 00:00:46.466
for cutting and forming metal,

24
00:00:46.466 --> 00:00:47.899
and create different gauges

25
00:00:47.900 --> 00:00:49.300
and other measuring devices.

26
00:00:49.300 --> 00:00:50.833
Die makers construct metal forms

27
00:00:50.833 --> 00:00:52.366
used to shape metal, and make

28
00:00:52.366 --> 00:00:53.899
molds for shaping plastics,

29
00:00:53.900 --> 00:00:56.266
ceramics, and composite materials.

30
00:00:56.266 --> 00:00:57.566
Tool and die makers are trained to

31
00:00:57.566 --> 00:00:59.132
write CNC programs as well as

32
00:00:59.133 --> 00:01:01.099
operate the machines.

33
00:01:01.100 --> 00:01:02.533
Workers wear safety glasses,

34
00:01:02.533 --> 00:01:04.166
earplugs, and masks when needed

35
00:01:04.166 --> 00:01:05.299
to protect themselves during

36
00:01:05.300 --> 00:01:07.133
hazardous phases of their work.

37
00:01:07.133 --> 00:01:08.766
Schedules are generally full time,

38
00:01:08.766 --> 00:01:10.032
with some shifts on evenings

39
00:01:10.033 --> 00:01:11.233
and weekends to keep production

40
00:01:11.233 --> 00:01:12.766
running around the clock.

41
00:01:12.766 --> 00:01:14.499
A high school diploma or equivalent

42
00:01:14.500 --> 00:01:16.466
is necessary, and skills in math

43
00:01:16.466 --> 00:01:18.399
and problem-solving are important.

44
00:01:18.400 --> 00:01:19.633
Machinists may train in 

46
00:01:20.866 --> 00:01:22.166
on the job, apprenticeship,

47
00:01:22.166 --> 00:01:23.899
or at technical colleges.

48
00:01:23.900 --> 00:01:25.333
Becoming a tool or die maker

49
00:01:25.333 --> 00:01:26.866
takes several years of instruction

50
00:01:26.866 --> 00:01:28.232
and on-the-job training.
