We'll be taking a look at the supply detail drawing 123 block drawing dot PDF.

It's important that we're able to identify datas and feature control
00:14
frames on detailed drawings when planning out our machining operations.
00:18
So the first thing that we want to do is identify data A B and C.
00:22
So we can know their location in reference to the part.
00:26
Next,
00:27
we want to make sure that we can view each of
00:28
the feature control frames and identify the symbols within them.
00:32
There are many different GD and T symbols and these are only three of them.
00:36
But if we take a look at the
00:38
feature control frame here listed as a positional tolerance
00:42
with a tolerance value of 0.0002
00:46
relative to data B and C,
00:49
this is letting us know that the position of these holes
00:51
are tightly controlled relative to both sides of the part.
00:55
As we look at it from the top view.
00:58
Even though datum C is placed on the front view,
01:00
we can still identify it based on the fact that we know the projection of our part.
01:05
And in this case, this detailed drawing has listed views for front top and right.
01:10
Also let's take a look at the
01:12
next feature control frame which list perpendicularity.
01:16
This has a similar tolerance 0.0002
01:20
relative to data B.
01:23
This means that the top face of the part must
01:25
be perpendicular to the side face referenced by data B
01:29
within that tolerance value.
01:31
And last, let's take a look at the third data.
01:33
This gives a parallelism.
01:36
In this case, we need to make sure that the face listed for the feature control frame
01:40
stays parallel to datum. A again with a tolerance of 0.0002.
01:46
These are all important aspects because they'll
01:49
determine how you not only hold your part
01:51
but also how you machine it and the order of operations that you decide to create.
01:56
In this case, a 123 block is a highly tolerance controlled part,
01:60
but we're not going to be machining this part per se.
02:02
It's just important that we identify these features on the detailed drawing.
02:06
So that way we can use them when planning our own parts.
