Set up and run
00:02
up two.
00:02
After completing this video, you will be able to
00:06
install soft jaws into a vice,
00:08
locate a coordinate system on those soft jaws run operation. Two of a part,
00:14
we used hard jaws for our first operation with parallels to support our part.
00:20
Now hard jaws are steel jaws with precision ground
00:24
surfaces that are not meant to be machined into.
00:27
For our second operation.
00:28
We will be using soft jaws
00:31
which are just aluminum or steel jaws that are meant to be machined into.
00:36
These are perfect for holding odd shaped parts during our secondary operations,
00:42
the vice goes on just like we showed you earlier.
00:45
But after everything is straight and tight,
00:47
we will remove our hard jaws and replace them with our soft jaws.
00:57
We will snug the jaws and then set them
00:60
with a dead blow hammer before tightening things completely.
01:03
Now, if we were installing soft jaws that had already been cut,
01:07
we would lightly snug everything, tap things down
01:10
and then clamp on a part,
01:12
clamping on a part before tightening the jaws completely will help align
01:18
that front and back jaws for us.
01:20
We chose to set our W CS work coordinate system
01:24
at the front left corner of our fixed jaw infusion.
01:28
So we need to set our machine work zero at that same spot.
01:33
We'll use the heimer to set our work offset.
01:36
If your machine is a probing system, that's what you'll be using.
01:39
We jog
01:40
our heer to read zero along the X axis, the left edge of our jaw
01:45
and then press the part zero set key with our G 54 work offset highlighted.
01:50
Now, we used W CS one in Fusion 360 which is G 54 which is why we're gonna use
01:58
G 54 work
01:60
offset for this single vice set up.
02:03
We could have added a second vice on the table
02:12
and G 55 for the second operation W CS two.
02:15
That's a good way of doing things,
02:17
but it's a lot more complicated. A lot more advanced.
02:20
We're gonna hit this part using only G 54 W CS one.
02:25
And in future parts, we'll show you that secondary set up and how to use those offsets
02:30
and how to separate things out. But again, for now,
02:32
we're sticking with wcs one.
02:35
OK?
02:35
We'll repeat the process for our Y axis,
02:38
making sure our G 54 Z work offset is set to zero
02:43
and then touch off both of the tools listed on our set up sheet
02:46
right on top of our back job.
02:50
And remember the reason that our G 54 Z value is set to zero
02:56
is that, that Z value
02:58
is simply the distance between where we touch off our tools
03:01
and where our work coordinate system is
03:03
because our work coordinate system is set at the top of our jaws.
03:07
And that is where we touch off our tools.
03:10
There's zero distance between those two
03:12
where we touch off our tools and where W CS is.
03:15
So our G 54 Z zero is
03:18
zero.
03:20
This is the same process we use for
03:22
one, except in our first operation. Our Z zero was right on top of our raw stock.
03:28
And that's where we set our tools
03:29
for this second operation. We've chosen to set our Z zero on top of our jaws.
03:36
This spot makes sense for this op when machining our soft jaws,
03:39
it's our only available feature.
03:41
It also highlights a different way that we can approach our work offsets.
03:45
When programming parts,
03:48
our tool and work offsets are all set and we're about ready to run the part.
03:51
But first, we're gonna show you another method that we can use
03:55
to verify that everything we've done to this point was done correctly.
03:59
Now, this might be
04:01
the most useful bit of G code that you will ever hear.
04:05
You'll wanna take this, write it down on a post it, note,
04:07
stick it in your pocket and save it for later here.
04:10
We go MD I
04:11
M six T two
04:14
G 54 G zero, G 90 X zero, Y zero, G 43 H two, Z 0.1 M 30. The M six T two is pretty simple.
04:25
Uh M six means do a tool change, T two says do a tool change to tool two.
04:31
Now we chose tool two in this case, because it's a pointy tool.
04:36
You'll see why in a moment. T two is our champ for two
04:39
M six T two.
04:41
We're in MD mode will go ahead and reduce our rapids to 25%.
04:46
Put the machine in single block mode
04:49
and run through this code.
04:51
So at this point, we can press cycle start
05:00
and sure enough, the machine did a tool change,
05:03
putting tool to our champ for tool into the spindle.
05:06
If we were to press the cycle start button again.
05:08
G 54 G zero, G 90 X zero, Y zero,
05:12
G 54 is our W CS one coordinate system which is right there on the corner of our jaw.
05:19
So we're gonna command it to G 00, which means go really fast to X zero, Y zero,
05:25
which is zero distance to the X zero distance in the Y
05:29
from our zero point, which is the corner of that job.
05:31
We want that tool to go right above our corner and verify
05:35
that we've said it correctly.
05:37
Uh G 90 we're not gonna talk about much. Uh
05:40
but again, it says just use a Cartesian coordinate system
05:43
that matches everything that we've used in school.
05:46
Uh Xy and Z and all of our commanded XYZ moves will be from that zero point.
05:52
That's what G 90 moves.
05:54
Don't think about it too much just yet.
05:56
Cycle start
05:59
and our machine moved so far, things look good.
06:02
But our tool is still well above our part.
06:05
We need it closer.
06:06
G 43 H two, Z 0.1
06:10
the G 43 H two simply means use offset two. Now, most of the time, almost all the time,
06:17
we use an offset number
06:19
that matches our T number, our tool number.
06:22
Uh That's just the way things work.
06:24
There are certain circumstances when you wanna use
06:27
tool 108 but offset eight,
06:30
we're not talking about that.
06:31
Uh We almost always use an offset number that matches our T number.
06:36
That's why we're using H two because it matches T two
06:39
G 43 just says use
06:41
offset H two
06:43
and go to
06:45
Z 0.1. Now, this is where scary things happen.
06:48
It's these Z moves that we need to verify.
06:51
Now, I've got my rapid set to 25%. I'm gonna press cycle start
06:55
and watch this tool come in.
06:58
That's fast.
06:60
I'm gonna stop it with the feed hold,
07:02
move from 25% rapid to 5% rapid
07:07
and let things come in.
07:11
Now, I stopped at just above the part here.
07:13
I'm gonna go ahead and go to my position screen
07:15
looking at our distance to go value that we talked about in previous videos.
07:19
Now this is how far our tool is gonna move in the Z axis if
07:23
we were to press that green button one more time while in single block mode,
07:27
and it says we have minus 0.2767 inches.
07:32
If we were to press position again,
07:35
move up and over to our program.
07:38
It's saying that we are should be 0.3767 inches above our jaws.
07:44
We can look above our jaw
07:46
and say, yeah, that looks reasonable.
07:48
That looks correct.
07:50
Once we've gotten to this point, we can press cycle start
07:54
and watch it come down,
07:56
stopping
07:57
at Z 0.1 just like we programmed,
08:01
we can open the doors,
08:03
look in the machine
08:05
and verify
08:06
that everything is where it should be
08:08
and it is, this is the safest way to verify that our work offsets our tool offsets,
08:14
everything match.
08:15
We've done everything right.
08:16
It's time for us to load up our program, run it in graphics and run our part.
08:22
We have gone ahead and clamped on a half inch spacer
08:25
and run a program that cuts our op to jaw force.
08:28
Now,
08:28
we are just giving you this short explanation for now as we'll
08:31
be covering the design and cutting of soft jaws in some detail,
08:35
incoming videos,
08:37
we can now load our part into our jaws and tighten the
08:40
vice handle a reasonable amount while holding our part down firmly.
08:44
We'll take our program from fusion 360
08:47
copy it onto the machine via USB,
08:50
run the program in graphics.
08:53
And if we are satisfied, we'll put the machine in memory mode,
08:56
lower our rapids a bit for our first approach
08:59
and press cycle start.
09:01
Now at this point, I might feed, hold somewhere above our part
09:06
and take a look at our position, screen my distance to go
09:10
and my, my work position.
09:12
And if things are looking good, I'm gonna take the machine out of single block,
09:17
increase my Rapids back up to 100%.
09:19
Press the green button and let things run.
09:26
And if we were a little bit timid about our speeds and feeds, uh,
09:30
we could have reduced our feed rate using those override buttons.
09:34
Heck, you could go all the way down to 50% feed rate if you wanted to
09:38
and then slowly increase the feed rate back up to 100% or more.
09:42
And if we don't like the way things sound
09:44
during this, this time,
09:46
we can adjust our program, go back into fusion 360
09:49
repost it.
09:50
Uh, for this type of part running on aluminum,
09:53
I would probably run at max R PM for whatever machine you have or close to it.
10:00
Now, back on the topic of speeds and feeds.
10:03
If our part had been pulled from the vice and prone
10:07
during machining, we likely didn't tighten our vice enough.
10:11
It's a balancing act too loose and our part could
10:14
come out too tight and we could crush it.
10:17
Now, this part looks great.
10:18
Now, we will know how good things actually are
10:21
when we go to measure it.
10:23
Now, I know this is a lot to take in but realize there are more videos yet to come.
10:27
We're gonna cover all these topics again and again,
10:30
you're doing great.
00:00
Set up and run
00:02

After completing this course, you’ll be able to:
