create a fixture plate
00:05
In this video,
00:06
we'll identify fix during requirements for a design and
00:08
will create a 3D model of a fixture plate
00:13
Infusion 3 60. Let's get started with our engine case. Rh no timeline
00:18
in this video, we're going to be creating a fixture plate to hold the design.
00:22
Fixture plates are a way that we can hold a design when it may
00:25
be a little bit more difficult or
00:27
problematic using traditional fixture in methods.
00:30
So oftentimes when you're holding a part in advice,
00:33
you need to have enough material to actually hold the
00:36
part to be able to get to all the features.
00:38
So what we're going to do today is we're going to
00:40
look at making a fixture plate to hold this part down,
00:43
assuming we had to add some additional details
00:46
and the part has already been machined.
00:48
So the fixture plate comes in at
00:50
various different aspects of the machining process.
00:53
And what I mean by that is oftentimes you'll use
00:56
it for the second operation when you're machining apart.
00:60
So you'll machine some features like these details that
01:04
are meant for roll pins or holes that are
01:06
either threaded or passing and then find a way that you can fix it to a plate.
01:11
So what we're going to do in this case is we're going to create a
01:13
fixture plate and I'm going to get started by first creating a new component.
01:18
Often times when you're working on a design in fusion 3
01:23
If you're working with bodies or components,
01:26
components are going to be very beneficial to the modeling process,
01:31
assuming that you're starting from scratch,
01:33
it's going to organize your timeline,
01:35
it's going to give you some additional benefits.
01:37
Things like being able to add joints for motion
01:39
and being able to create exploded views for detailed drawings
01:42
for us.
01:43
However,
01:43
we're going to just create a component so that
01:45
we understand the process of how to do it.
01:48
I'm going to rename the component fixture plate,
01:51
I'm going to make sure that it's internal,
01:52
which means that it's going to be saved in the context of this design.
01:56
It's going to be a standard type, not sheet metal and we're going to activate it,
01:60
which means we're going to start working on it right away when we activate it,
02:04
the opacity of the standard engine case, Rh body
02:08
Has changed too,
02:09
I think it's about 10 or 15% and that means that it's
02:13
easier for us to focus on what we need to create.
02:16
Now,
02:16
the first thing that I want to do is actually start a new sketch on the
02:20
face of this part because I want to reference all of the details that are needed.
02:24
Notice that the fixture plate component has a radio button next to it,
02:28
just like the very top level of our design
02:30
and if we go back and forth, it's important to note that activating,
02:34
it will not only change the opacity of everything else,
02:36
but it also ensures that anything we do
02:39
is contained in the context of that component.
02:42
So we're going to get started selecting the face of this body,
02:45
we're going to right click and create a sketch.
02:48
The next thing I want to do is slightly rotate this around,
02:51
I'm going to go to create project include and project.
02:55
And I also want to bring in the actual diameter of
02:58
these pinholes and that's because by selecting the outside face,
03:02
all we're doing is we're bringing in the outside
03:04
of the champ for so we're going to say,
03:06
okay,
03:07
and I'm gonna go back to a right hand view.
03:10
Next I want to actually create a circle or a hole here,
03:14
that's going to be a tapped hole.
03:15
So I'm going to use the circle tool,
03:17
going to find the center point here and I'm going to say 0.0.201,
03:22
that's going to be my tap size for quarter 20 we're gonna do the same thing again.
03:26
However,
03:27
this time instead of entering a dimension we're going to use
03:29
the equal constraint to make sure that both of these are equal
03:33
Had escaped to get off our constraint tool.
03:35
And the last thing that I'm going to do is use an offset
03:37
of the outside profile and I want to bring this in just slightly,
03:42
I'm going to do -12.
03:44
And the reason that I want to do this is because if I'm bolting down to a fixture plate,
03:49
there's a chance that I actually want to take the end
03:52
mill all the way down past the end of my part.
03:54
So sometimes I like to make a little offset or an inset section,
03:59
so that allows me to take the tool down that far.
04:02
The last thing that we need is the actual outside
04:04
profile of whatever we're creating now for this part,
04:08
the origin is actually up here.
04:10
So I'm going to use a two point rectangle and I'm going
04:12
to start somewhere outside of here and come down over here.
04:17
The way that I want to define this is by using some dimensions and some constraints.
04:21
So I'm gonna grab my line tool and I'm going to go from this corner up to the
04:26
top and this corner over to the side and I'm going to do the same thing down here.
04:31
I'm gonna come over here and down here.
04:34
And the main reason that I want to do this
04:36
is because I'm going to turn these into construction lines.
04:39
So we're going to select each of these
04:41
because they don't actually have to be selectable,
04:43
Turn them into construction, which means it won't affect my profile.
04:47
Then I'm going to use my equal constraint now for equal constraint,
04:51
I want to ensure that the offset on both sides in the
04:54
horizontal direction is the same and that offsets in both sides,
04:58
in the vertical direction are the same,
04:60
then I can use my dimension tool to come up with some good values that can
05:04
be held in a vise easily and are also easy enough for us to manufacture.
05:09
So I'm going to say 1.75
05:12
And then for the width,
05:14
I'm gonna say 2.75,
05:18
we'll finish the sketch and now this sketch contains everything that we need.
05:21
So I'm going to hide the original body because I don't need to see it right now.
05:25
And then I'm going to start creating an extrude
05:28
for this extrude.
05:29
I want to begin by selecting my offset piece here and I need to grab these
05:33
little sections because remember that we're going to
05:36
be using a pin to help locate this.
05:38
And I also want to grab these sections of the
05:40
holes because we're going to be creating a tapped hole.
05:43
So I need to decide how deep this section needs to be for a part like this,
05:49
I'm just going to say 1/16 so 0.625 and hit enter.
05:54
Then I'm going to go back into my sketches.
05:57
I want to show that sketch and then I'm
05:59
going to create another extrude for this Extrude.
06:02
What I want to do is select the entire part. As well as all these inside sections.
06:08
I need to make sure that I grab all of these profiles.
06:11
This can be difficult sometimes just simply based on the
06:14
fact that we now have a solid body here.
06:16
So you need to make sure that you go around and
06:18
you select all the pieces that are of interest to you.
06:21
Sometimes you can hide the solid body if it makes it a little bit easier,
06:25
you will get a warning because you're trying to create a
06:27
solid body and the Solid bodies folder is currently hidden.
06:30
But that's okay because we're going to turn it back on
06:33
as soon as we go and get ready to create a solid
06:36
Now that we have everything that's important to us,
06:39
I'm going to turn the solid bodies folder back on and I
06:42
want to create this starting as an offset from the object.
06:46
And the reason I want to use object is
06:48
because this gives me something that I can select.
06:51
You'll notice that it's hard because we've already extrude. Cut it through.
06:54
So I'm going to just go the other direction for this and
06:57
then we can select the object as the backside of this part.
07:01
We're going to join them together
07:03
And the direction is going to be this way we want to go away from our part.
07:07
Now,
07:08
the overall distance here is something that we need to think about because this
07:12
is going to be the overall size of the stock that we start with.
07:15
Does it really need to be half an inch thick or can it be 3/8 or something smaller.
07:20
And keep in mind that this value is in addition to the 16th that we've already added.
07:26
So if we want to look at the overall height,
07:28
what we can do is we can say that we want to extrude up to an object.
07:34
I'm going to select this face and then for the offset type,
07:38
I'm going to put in a minus value and say minus 0.5,
07:42
notice that it completely goes away
07:45
and if we try to change the adjacent faces, this doesn't work.
07:49
If we change this to a positive 0.5, it works but it's going the wrong direction.
07:53
So in this case it's not able to use that face as the reference for us.
07:58
So the best way that we can define this is to restart our selection process.
08:04
And instead of starting from an object,
08:07
we're going to use an actual offset from our sketch plane.
08:09
So in this case, let's say that we wanted a half inch stock.
08:14
This means that we're starting half inch away from our sketch plane
08:17
and the distance can be up to object
08:20
and we can join them together.
08:21
We need to make sure that we set that off set back to zero and then we can say, okay,
08:27
let's temporarily hide the sketch and just take a look at what we have.
08:30
So essentially we have a half inch thick block.
08:33
If we use inspect to measure the top and the bottom,
08:37
we have a half inch thick block and we're
08:40
removing material from the top of this as well as
08:43
creating some tapped holes and we have some holes here
08:46
that are going to be used for roll pins.
08:48
Now we have to think about the pins that are going to be
08:51
used in a lot of cases you want to use a threaded tapered pin
08:55
and in other cases you might just have a pin that press fits into this hole and that's
09:01
going to determine what size this whole ends up being and how deep the hole has to go
09:05
the same thing with this.
09:06
Typically we would want to do a quarter 20 tap and we would not want to use a blind hole.
09:11
We wanted to go all the way through.
09:14
Some other things to consider when making a fixture plate is going
09:18
to be where you want your coordinate system to be located.
09:22
So if we're going to be using a fixture plate
09:24
and we're going to be machining the original body,
09:27
then we would need to think about how much stock is on the actual part.
09:32
If our coordinate system is going to reference the original part or
09:36
if we're going to be able to reference the fixture plate.
09:39
Oftentimes when you're using a fixture plate, it's because you have to
09:42
add and remove multiple parts or you have to
09:45
run the same operation over and over again.
09:47
So your coordinate system reference makes sense to be on the fixture itself,
09:52
but you have to be real careful with something like this.
09:54
Your Z height could be up to 1/16 off depending on how you set up your program.
09:60
So you need to be especially clear when you're setting up your X,
10:03
Y and Z coordinate systems
10:06
whenever you're making a fixture,
10:07
it's always a good idea to include some text or reference on the fixture itself.
10:13
So that way you can engrave that detail after the fact.
10:16
This can be done fairly easily by simply creating a new sketch
10:21
and we can go to create and add text.
10:24
We're going to draw a text box
10:27
and our sample text is going to be X. Y Z. We might need to reduce its size.
10:33
You can see that the text size is quite large. So if we change this to let's say 0.1
10:39
and now you can see that we've got X Y Z.
10:42
We can also add to this and potentially point an arrow to the corner.
10:47
But I'm not going to go into that level of detail here.
10:49
Once we have the text we can select it and extrude it just like we would anything else.
10:54
And now we have a feature that's located here that will let us come
10:58
back after the fact and use engraving tools to just simply put X.
11:02
Y. Z in there
11:03
A lot of times.
11:04
You'll also see other features such as a circular boss that can be
11:09
used for probing to find your G- 54 or your coordinate system location.
11:14
This can be located anywhere.
11:15
But the main thing you want to make sure that you remember
11:18
is that the coordinate system has to match your digital twin,
11:21
your set up inside of the camp software and the way it's set up on the machine.
11:26
So just make sure that there are notes,
11:28
make sure that features are clear and make sure that
11:31
everybody is well aware of where the coordinate systems will
11:34
be because otherwise it could be a pretty dramatic end
11:37
to a part tools and even sometimes a machine.
11:41
So at this stage I want to make sure that I activate the very top level.
11:45
I am going to do a save as for this part.
11:49
So I'm going to go to file save as and
11:52
I'm going to say engine case right hand with fixture.
11:57
Now it's not strictly required that I save it as a new design but it does really help me
12:02
sort of differentiate between the different designs that were
12:05
going to be looking at at this stage.
12:07
I think it's a good idea for you to just remind
12:09
yourself of what we did in terms of creating a component,
12:13
projecting geometry and creating some references like the X,
12:17
Y Z text on our fixture plate.
12:19
But at this point, once you're done,
12:20
make sure that you do save your design and move on to the next step

solid body and the Solid bodies folder is currently hidden.
06:30
But that's okay because we're going to turn it back on
06:33
as soon as we go and get ready to create a solid
06:36
Now that we have everything that's important to us,
06:39
I'm going to turn the solid bodies folder back on and I
06:42
want to create this starting as an offset from the object.
06:46
And the reason I want to use object is
06:48
because this gives me something that I can select.
06:51
You'll notice that it's hard because we've already extrude. Cut it through.
06:54
So I'm going to just go the other direction for this and
06:57
then we can select the object as the backside of this part.
07:01
We're going to join them together
07:03
And the direction is going to be this way we want to go away from our part.
07:07
Now,
07:08
the overall distance here is something that we need to think about because this
07:12
is going to be the overall size of the stock that we start with.
07:15
Does it really need to be half an inch thick or can it be 3/8 or something smaller.
07:20
And keep in mind that this value is in addition to the 16th that we've already added.
07:26
So if we want to look at the overall height,
07:28
what we can do is we can say that we want to extrude up to an object.
07:34
I'm going to select this face and then for the offset type,
07:38
I'm going to put in a minus value and say minus 0.5,
07:42
notice that it completely goes away
07:45
and if we try to change the adjacent faces, this doesn't work.
07:49
If we change this to a positive 0.5, it works but it's going the wrong direction.
07:53
So in this case it's not able to use that face as the reference for us.
07:58
So the best way that we can define this is to restart our selection process.
08:04
And instead of starting from an object,
08:07
we're going to use an actual offset from our sketch plane.
08:09
So in this case, let's say that we wanted a half inch stock.
08:14
This means that we're starting half inch away from our sketch plane
08:17
and the distance can be up to object
08:20
and we can join them together.
08:21
We need to make sure that we set that off set back to zero and then we can say, okay,
08:27
let's temporarily hide the sketch and just take a look at what we have.
08:30
So essentially we have a half inch thick block.
08:33
If we use inspect to measure the top and the bottom,
08:37
we have a half inch thick block and we're
08:40
removing material from the top of this as well as
08:43
creating some tapped holes and we have some holes here
08:46
that are going to be used for roll pins.
08:48
Now we have to think about the pins that are going to be
08:51
used in a lot of cases you want to use a threaded tapered pin
08:55
and in other cases you might just have a pin that press fits into this hole and that's
09:01
going to determine what size this whole ends up being and how deep the hole has to go
09:05
the same thing with this.
09:06
Typically we would want to do a quarter 20 tap and we would not want to use a blind hole.
09:11
We wanted to go all the way through.
09:14
Some other things to consider when making a fixture plate is going
09:18
to be where you want your coordinate system to be located.
09:22
So if we're going to be using a fixture plate
09:24
and we're going to be machining the original body,
09:27
then we would need to think about how much stock is on the actual part.
09:32
If our coordinate system is going to reference the original part or
09:36
if we're going to be able to reference the fixture plate.
09:39
Oftentimes when you're using a fixture plate, it's because you have to
09:42
add and remove multiple parts or you have to
09:45
run the same operation over and over again.
09:47
So your coordinate system reference makes sense to be on the fixture itself,
09:52
but you have to be real careful with something like this.
09:54
Your Z height could be up to 1/16 off depending on how you set up your program.
09:60
So you need to be especially clear when you're setting up your X,
10:03
Y and Z coordinate systems
10:06
whenever you're making a fixture,
10:07
it's always a good idea to include some text or reference on the fixture itself.
10:13
So that way you can engrave that detail after the fact.
10:16
This can be done fairly easily by simply creating a new sketch
10:21
and we can go to create and add text.
10:24
We're going to draw a text box
10:27
and our sample text is going to be X. Y Z. We might need to reduce its size.
10:33
You can see that the text size is quite large. So if we change this to let's say 0.1
10:39
and now you can see that we've got X Y Z.
10:42
We can also add to this and potentially point an arrow to the corner.
10:47
But I'm not going to go into that level of detail here.
10:49
Once we have the text we can select it and extrude it just like we would anything else.
10:54
And now we have a feature that's located here that will let us come
10:58
back after the fact and use engraving tools to just simply put X.
11:02
Y. Z in there
11:03
A lot of times.
11:04
You'll also see other features such as a circular boss that can be
11:09
used for probing to find your G- 54 or your coordinate system location.
11:14
This can be located anywhere.
11:15
But the main thing you want to make sure that you remember
11:18
is that the coordinate system has to match your digital twin,
11:21
your set up inside of the camp software and the way it's set up on the machine.
11:26
So just make sure that there are notes,
11:28
make sure that features are clear and make sure that
11:31
everybody is well aware of where the coordinate systems will
11:34
be because otherwise it could be a pretty dramatic end
11:37
to a part tools and even sometimes a machine.
11:41
So at this stage I want to make sure that I activate the very top level.
11:45
I am going to do a save as for this part.
11:49
So I'm going to go to file save as and
11:52
I'm going to say engine case right hand with fixture.
11:57
Now it's not strictly required that I save it as a new design but it does really help me
12:02
sort of differentiate between the different designs that were
12:05
going to be looking at at this stage.
12:07
I think it's a good idea for you to just remind
12:09
yourself of what we did in terms of creating a component,
12:13
projecting geometry and creating some references like the X,
12:17
Y Z text on our fixture plate.
12:19
But at this point, once you're done,
12:20
make sure that you do save your design and move on to the next step
