Machine Operation 2

00:01

Machine soft jaws.

00:03

After completing this video, you will be able to

00:06

run soft jaw, tool paths,

00:09

inspect soft jaws

00:11

and complete a two vice set up

00:16

in this series. We have run single operations in single visas a few times now.

00:22

But each time we were using G 54 W CS one and we

00:26

were touching off our tools right on top of our raw stock.

00:30

This was a good way of doing things,

00:32

but we are advancing now and it's time to show you another approach for

00:37

setting up our Z offsets on our machine that allows us to run multiple parts

00:42

and multiple set ups on a machine. All at the same time,

00:45

this is tool five,

00:47

our quarter inch end mill that we will be using to machine out our op two soft jaws.

00:53

If we were running our second operation in just this single vice,

00:57

we could touch off this T five right on top of our soft jaws,

01:03

but we can't do that right now.

01:06

This tool has already been spoken for.

01:09

We already touched it off on top of our raw stock

01:13

on our G 54 W CS one.

01:16

If we were to touch off that tool again. Now, in a different location,

01:20

it would mess up our op one

01:24

here is what we're gonna do for. Now, we're gonna set all of our tools

01:29

on the exact same plane, the exact same location just like we always do.

01:33

And we're gonna make that location right here on top of our G 54 stock because

01:39

it's already been done last video, we've already run this part.

01:42

The setup still exists from last time.

01:45

All of our tools are being touched off right here

01:49

done for now, all of our tools have been touched off

01:54

on that single location.

01:55

Now, for this operation, our G 55

01:59

the control just needs to know the distance between our

02:03

two Z zero

02:05

and the surface where our tools were touched off and

02:08

we'll figure that out and enter that value

02:11

as our G 55 Z work offset.

02:14

We'll use our 3D indicator again. But, but you could use any indicator.

02:19

Now, we will zero out our indicator on top of our touch off location

02:23

while in hand jog mode.

02:26

Now, while in hand jog mode, we can see our position at the bottom of our screen.

02:30

I want you to focus on this distance to go column if we exit and

02:35

then re enter hand jog mode by pressing memory and then hand jog again,

02:40

we will have zeroed out our distance to go position screen.

02:43

This is just a feature of the control.

02:45

Now as we jog our distance from our touch off location

02:50

is shown right here for us to see

02:54

we can now hand jog our indicator up and over and

02:57

back down to the top of our G 55 Z location,

03:01

the top of our op two jaw.

03:04

This is our distance from our touch off location

03:07

to our G 55 W CS two location.

03:11

This is the value that we need.

03:14

We will take this distance and enter it onto our work

03:17

offset page as our G 55 Z value.

03:21

Our plus or minus signs do matter here. So I guess it is a, is a vector,

03:25

uh not just the distance because it has a direction as well plus or minus

03:31

to recap. Our G 55 Z value is just the plus or minus distance from where we set our tools

03:38

to our G 55 Z zero location.

03:42

Now, for our G 54 our first operation,

03:45

the distance from where we set our tools

03:48

to our G 54 Z zero

03:51

was zero. It was the same surface, the same location.

03:54

So we have zero as our G 54 Z value.

03:59

Our job program program 2000 dot NC posted from Fusion 360 uses only one tool T five.

04:07

Now we touched it off at the same location as all of our other tools

04:11

set our G 55 Z value as a distance from our touch off location to our G 55 Z zero.

04:17

And we are ready to verify our set up.

04:20

We will pull out our trusted post it note

04:23

and adjust our code to use tool five

04:27

H

04:28

offset five

04:29

and G 55.

04:32

We will enter this into MD. I

04:37

press the single block key,

04:39

lower our rapids to 5%.

04:42

Close the doors and press cycle start now because we are in single block mode.

04:47

The control will execute just one line of code

04:50

with each push of our green cycle start button.

04:54

We will keep our finger on the feed hold button

04:56

and an eye on our distance to go and G 55 work positions.

05:01

As our tool approaches our vice,

05:03

we will press feed, hold

05:05

above our jaws.

05:07

Look at our distance to go value and ask ourselves if the value is reasonable.

05:12

This is how far our tool will move

05:14

in each axis. If we press that green button again,

05:18

this looks reasonable

05:20

like the tool could safely move this amount

05:23

so we can continue check all of our offsets again.

05:25

Now, in this case, our tool has stopped just above

05:29

that front, left corner of our

05:31

two back jaw. As expected

05:34

from this, we can tell that our G 55 XY values are set correctly.

05:39

Our tool stopped about 0.1 inches above our jaw

05:43

just as commanded.

05:45

So we can tell that our tool offset and our G 55 Z work offsets

05:50

are also set correctly.

05:52

There's a lot to take in

05:54

but setting and checking our tool and work offsets will become second nature to us.

05:58

The more often we do set ups.

06:01

And at this point,

06:02

I feel like we've moved from basic to advanced and I should give you something.

06:07

Uh So here you go. Here is a gold star for working so hard and sticking with it.

06:14

Many of your machining instructors

06:16

are gonna teach you a different way to touch off your tools.

06:19

They might use a 123 block on the top of their

06:22

table and set all of their tools on top of that.

06:27

We can then take the distance from the top of our 123 block. Our touch off location

06:32

to each one of our G 54 G 55 parts and use that distance

06:37

as our work off at Z value.

06:39

And this is a good way of doing it.

06:41

Uh We're not tied to any certain material for setting our tools.

06:46

And

06:47

the reason we might want to do it that way,

06:49

choosing some other location to touch off

06:51

all of our tools when using multiple devices

06:54

is that, let's say I run all of my material. I have no more stock for

06:58

one. It's all gone. We machined out all of our material.

07:01

If I were to break a tool, running

07:03

our op two, where would I touch it off?

07:06

There's no more touch off location

07:09

to use. We, we've created a problem. So

07:12

running a single vice and touching off right on top of our

07:15

material that's fast and easy and you need to learn that.

07:18

That's day one.

07:20

But when you start getting into multiple vices, multiple fixtures,

07:24

multiple parts,

07:26

a lot of people move over and start using

07:28

a single touch off location other than their stock,

07:32

our vice is set up, our tool and work offsets are set and verified.

07:36

We can now load up our job program

07:42

inside of Fusion 360 we can simulate our soft jaw operation

07:47

so we can know how things should look

07:49

and at the control with our program loaded and verified,

07:52

we can press the graphics key to enter graphics mode

07:56

where we will verify our program again.

07:59

We need to make sure that our program is using G 55.

08:03

That's W CS two from Fusion 360 to match how

08:07

we have set things up in this example as well.

08:10

We always verify our work offset number and our T tool numbers.

08:17

Now, once we have confirmed things graphically,

08:19

we exit graphics mode by pressing the memory key,

08:23

verify the correct program is active.

08:26

Make sure that we are at 5% rapid. So we can feed, hold if necessary

08:30

and we can press the cycle start button

08:32

and watch the tool slowly move towards our part.

08:35

We can once again press feed, hold just above our part,

08:39

making sure that our program and our distance to go values look reasonable,

08:42

making sure that the tool looks like it's starting in the correct location

08:47

and that our coolant nozzles are aimed at the tool. Once we are confident,

08:51

we can again press the green button

08:53

and watch our program run

09:15

with our jaws cut, we can open up our vice, remove our spacer

09:20

and check our part for a proper fit.

09:23

Now,

09:23

the nice thing about using aluminum jaws instead of steel is that

09:27

the material will better form to fit the part after a few pieces

09:31

and the jaws are less likely to mar our parts.

09:34

Great job running multiple set ups is definitely a lot more work,

09:39

but it's gonna save us time cycle time

09:42

uh in the long run.
