00:00:10,730 --> 00:00:16,010
Part one of our three part introduction to turning series, firstly, a list of

2
00:00:16,010 --> 00:00:20,130
the tools and materials which will be used throughout the series, starting with

3
00:00:20,130 --> 00:00:25,010
the aluminium bar, which will be used to create a small component.

4
00:00:25,010 --> 00:00:28,650
Using the center lathe, along with the basic knife tool.

5
00:00:28,650 --> 00:00:33,730
The knife tool will be used for facing off, turning into a diameter as well as a

6
00:00:33,730 --> 00:00:37,290
small chamfer on the front end.

7
00:00:37,290 --> 00:00:42,130
During the turning into a diameter phase we will also be using a 25 to 50

8
00:00:42,130 --> 00:00:47,250
millimeter micrometer for accurate measurements of the diameter and also to set

9
00:00:47,250 --> 00:00:48,970
the digital readouts on the machine.

10
00:00:49,490 --> 00:00:53,250
We will then move on to form a thread, a female thread on one end using the

11
00:00:53,250 --> 00:00:59,090
Jacobs chuck and key, a number four centre drill, an eight and a half

12
00:00:59,090 --> 00:01:01,370
millimeter tapping drill.

13
00:01:01,370 --> 00:01:06,170
Then we will later go on to use the tap wrench with a series of taps.

14
00:01:12,810 --> 00:01:16,650
This part of the process will also require the use of some lubricant.

15
00:01:20,010 --> 00:01:24,730
The square drive chuck key is used for tightening the material into the chuck

16
00:01:24,850 --> 00:01:27,770
and securing its in place for the work to be done.

17
00:01:27,770 --> 00:01:32,610
To begin with, we mount the knife tool into the tool post a simple case of

18
00:01:32,610 --> 00:01:37,050
slotting it into the preformed slot and then tightening it up to make sure that

19
00:01:37,050 --> 00:01:41,690
it's secure. It has already been pre centred ready for turning, mounting the

20
00:01:41,690 --> 00:01:46,810
material into the chuck, tightening up with the chuck key and giving a little

21
00:01:46,810 --> 00:01:49,250
nip at the end just to make sure that it's fully secured.

22
00:01:52,970 --> 00:01:55,090
Safety first, make sure the guard is lowered.

23
00:01:58,130 --> 00:02:02,210
Using the lever, we switch the machine on and then we begin to manoeuvre the

24
00:02:02,210 --> 00:02:06,730
knife tool into position to touch onto the material and begin the facing off

25
00:02:06,730 --> 00:02:13,410
process. When initially touching on, it is a good idea to go slowly at first

26
00:02:13,770 --> 00:02:17,330
removing only a small piece of material and to see how it's responding.

27
00:02:20,650 --> 00:02:25,130
Once satisfied with the initial touching onto the material, manoeuvre the knife

28
00:02:25,130 --> 00:02:30,690
tool into position to begin facing off properly and create a nice, smooth datum face.

29
00:02:42,210 --> 00:02:46,610
The knife tool is doing its work in removing that material from the front face

30
00:02:46,610 --> 00:02:48,490
and the new front face is being revealed.

31
00:02:51,010 --> 00:02:55,930
And this front face, once finished, will be a nice, smooth, even datum face.

32
00:03:00,130 --> 00:03:06,010
Speeding up the process to save time, 
a nice, even smooth datum  faces is emerging.

33
00:03:13,730 --> 00:03:17,010
Coming up now to the last
piece of material to be removed.

34
00:03:19,570 --> 00:03:26,290
Back into real time, touching off the material and switching off the machine.

35
00:03:26,290 --> 00:03:31,890
Winding the knife tool away to allow room to inspect the material, a good

36
00:03:31,890 --> 00:03:36,410
result, the new face of the material is smooth and balanced and ready for the

37
00:03:36,410 --> 00:03:39,970
digital readout to be calibrated on set at zero.

38
00:03:42,130 --> 00:03:46,810
To do that, the knife tool needs to be touched back onto the material.

39
00:03:46,810 --> 00:03:52,210
The Z axis on the digital readout will be set as a datum, recalibrating it to

40
00:03:52,210 --> 00:04:00,690
zero. This concludes facing off a piece of material, the knife tool was

41
00:04:00,690 --> 00:04:05,850
mounted, then touched onto the material, faced off the material and

42
00:04:05,850 --> 00:04:10,770
recalibrated the new faces of datum using the digital readout.

43
00:04:10,770 --> 00:04:15,210
In the next video, we will turn the material into a new diameter and also a

44
00:04:15,210 --> 00:04:16,530
small chamfer on the end.
