Machine Operation four of a part
00:06
in this video.
00:06
We'll create a counter bore and will create a chance for two deeper apart
00:12
infusion 3 60.
00:14
We want to carry on with our engine case,
00:16
Rh ready to program at this point we've created up 12 and three.
00:20
So we've machined the top of the part,
00:22
the bottom of the part as well as all of the critical details on the inside of the part.
00:28
Now is the time for us to create our fourth and final
00:30
operation to machine the counter boards on the outside of the part.
00:34
So in order to do this, we're going to go ahead and create a new setup
00:39
And I want to make sure that I do show the correct vice.
00:41
So we're going to be showing the vice for op four.
00:44
We want to make sure that all of the correct
00:46
bodies are shown and inside of the rear Jaw.
00:49
We do want to make sure that we are showing the correct parallels for this.
00:54
We're going to be using the 1.625 parallels again.
00:58
The next thing that we need to do is we
00:59
need to account for the model that we're machining again,
01:02
this is going to be our part.
01:04
We need to account for our fixture which is going to be generic vice for
01:09
and we need to account for our
01:10
stock from proceeding setup and continue rest machining
01:14
when we take a look at our coordinate system.
01:16
We need to make sure that the coordinate system is in the right location.
01:18
So let's go ahead and rotate this around.
01:21
Let's zoom in
01:22
and make sure that the orientation of the coordinate system is correct.
01:25
So we need to reset our Z and X. Z is going to be in the X direction.
01:30
So again, I'm going to hold down the left mouse button, select X,
01:33
flip Z. So it's pointing up and we're going to flip X.
01:37
So it's pointing in the correct direction.
01:39
Then we're going to be using a model box point.
01:42
And even though there's a fill it in this corner,
01:43
we're going to be grabbing this upper left hand corner,
01:46
which is the projection of the top and the side face.
01:49
Remember this is the location of our coordinate system for op three.
01:53
So in reality, if we have a stop and we've set Z,
01:56
we should be able to just flip the part over and put it back in the vice as is
02:01
when we're using a stop. Vices.
02:03
Oftentimes have a groove in the top of the fixed jaw and these can be used
02:07
to create a stop or you'll have a stop that's just attached to the side.
02:12
In our case, we don't have one in the model,
02:14
we're just going to assume that we're using a stop,
02:17
but we could always reset our coordinate system as well.
02:20
We also want to post process this, it's going to be 1004.
02:25
The comment is going to be op four
02:28
engine case and we're going to use that
02:30
same wcs offset three because again we can just
02:34
flip the part over and if we've already set
02:36
this in our coordinate system on our machine,
02:38
all we need to do is flip the part and the coordinate system is already set,
02:42
we're going to say okay.
02:43
And now we've got our new setup.
02:45
Once again we want to rename this O P four,
02:49
then we want to right click and create our associated named view.
02:53
Remember with the synchronization settings,
02:55
re selecting the ops will automatically show the correct vice as
02:60
well as the orientation that we create our name view in
03:03
at any point in time. If you want to change it.
03:05
For example, if you want to zoom in a bit more,
03:07
you can right click on the name view and you can update this.
03:11
That means when you go to select another operation and come back,
03:14
you can see that it's automatically zoomed back in.
03:18
So from this orientation we don't really have to do very much.
03:21
All we have to do is counter board these holes.
03:24
Now the counter board can be done a couple of different ways but we're
03:28
going to be just using a two D contour to finish this off.
03:32
The main reason that we're doing this is because the counter board size is 0.45 which
03:37
means that we can't get a large tool in there and it's also pre drilled.
03:42
There is a 2 57 hole that's been pre drilled in the center which means that we
03:46
can very easily come in here with a quarter inch end mill with one or two passes.
03:51
This is also not a critical feature,
03:53
it just needs to be big enough so that the head
03:55
of a quarter inch bolt can recess into the case.
03:58
So again we're going to use a two D. Contour but you could use a two D.
04:02
Pocket or several other types of operations.
04:05
We want to make sure that we do select the correct tool.
04:08
We're going to be using tool number five or quarter inch flat end mill
04:12
and we need to make sure that we select an appropriate cutting data preset.
04:16
Remember that this one automatically comes in at about 12,000 rpm.
04:20
So we want to set this to 7500.
04:23
Again we want to set the ramp spindle speed to 7500.
04:26
If you happen to use a spindle speed that is too large for your machine,
04:31
it will automatically throw a warning when you go to post the code.
04:34
If you don't have that spindle rpm limit set inside of your post processor,
04:40
then you will be able to generate code without actually
04:43
getting the warning until you take it to your machine.
04:45
So now that we have the tool parameter set,
04:48
let's go ahead and move on to geometry inside of here.
04:51
We need to select our contours which is fairly straightforward.
04:53
We just want to select the inside edge fusion
04:57
automatically knows which side we want to cut.
04:59
But if you happen to have to change it, all you need to do is click on that red arrow,
05:03
We don't need to worry about stock contours.
05:05
All we need to do is move on to our heights,
05:08
make sure it's referencing the selected contour.
05:11
The passes, we're not leaving any material.
05:13
We need to determine if we need to do multiple finishing passes,
05:17
depending on how much stock is left.
05:19
So what we can do is we can turn on multiple
05:22
finishing passes and determine how much those finishing passes are removing.
05:26
I'm going to leave this at .25 and then
05:29
we're going to move on to our linking parameters
05:32
in linking parameters, we have pre drill positions.
05:35
So this allows us to select the center point of this whole
05:38
and it's going to use that for its entry and exit positions.
05:41
Notice that it cannot use the drill positions
05:44
because keep tool down is not activated.
05:47
We're going to select no to not allow or not ignore that warning.
05:51
We're going to turn on. Keep tool down and say okay,
05:55
what's important here that even with keep tool down,
05:58
we do see a yellow rapid movement
06:00
that goes up above the part moves over to the next hole and down
06:05
this rapid movement is based on the heights.
06:07
And if you want to keep this closer to the part,
06:09
you can adjust the retract heights and keep the tool a little bit closer.
06:12
Also note when we view this from the side
06:15
that the blue lines are where the tool is starting, its feed motion.
06:19
So again if you want to reduce the feed and retract values
06:22
you can get it a little bit closer to the part.
06:25
Now that we have the counter boards created.
06:27
The last thing that we want to do is come back in with the two D.
06:30
Champ for and we want to de burr that whole
06:33
the two D champ for tool is already selected.
06:35
Then we just need to select our geometry
06:38
for this.
06:38
We're going to select a partial contour because we're not going to allow
06:42
this to go all the way up and down around the edge.
06:45
We just want to make sure that we come in and we Deborah this.
06:48
So what we're going to do is hold down the
06:49
key which
06:51
select partial chains. We're going to select this chain and then hold down the
06:55
key to select this one
06:57
Inside of our passes section. Again we're going to do .01 for our champ for width
07:02
five for the tip offset because these holes are large enough.
07:06
We don't have to worry about gouging anything and we're
07:09
going to leave the chance for clearance at .01.
07:12
It's the same settings we use for most of our other dippers.
07:15
So now you can see the tool is coming in and it is delivering this.
07:19
But what would happen if we did try to include the rest of this with our deeper tool?
07:23
Well, we do need to think about what that's going to look like with the tool.
07:27
So let's show hide the tool
07:30
and let's simply move it over to this edge.
07:33
So as this tool moves over to the edge in this orientation,
07:37
as we get to the bottom of that edge,
07:39
you can see that we're using a different portion of the tool,
07:42
so it's not going to give a very consistent result if
07:44
we try to use this tool to come down this edge.
07:47
So in this case it's not a great option for us.
07:50
We want to make sure that we're only champ offering or d bring the upper sections
07:56
From here. Let's make sure that all of our operations are named.
07:59
Let's go ahead and go back to op one
08:02
and let's make sure that everything saved before we move on to the next step

01:30

01:33
flip Z. So it's pointing up and we're going to flip X.
