Simulate toolpaths and operations

00:02

simulate tool paths and operations.

00:05

After completing this video,

00:06

you'll be able to simulate a single tool path and simulate a setup

00:14

infusion 3 60. Let's carry on with our mounting block.

00:17

If you had any difficulty you can upload the supply data set,

00:19

mounting block ready to sim dot f three Z.

00:23

Make sure that when you open it up that you do

00:25

turn off the Hoss VF1 inside the top of our setup.

00:29

In order to validate our tool paths we can use

00:32

in process stock which is turned on by default.

00:34

When we select a tool path will get a green preview of the

00:38

stock on the screen and we can see the material that's been removed.

00:42

With each tool path will be able to change

00:44

some of our display settings such as whether or not

00:46

the tool path is displayed if the stock is

00:48

displayed if the tool is displayed and so on.

00:51

However, there are other ways in which we can simulate tool paths in fusion 3 60.

00:56

For example when we take a look at our two D adaptive tool path

00:59

when it's selected and we see the in process stock on the screen,

01:02

it doesn't necessarily tell us everything we need to know.

01:05

For example the material left in the center. When we move on to our two D.

01:08

Pocket, how is that removed? And how does it affect the tool wear and tool life

01:13

with that tool path selected.

01:14

We can go to actions and select either simulate or

01:17

simulate with machine because we do have a machine selected

01:20

for now let's use this simulate option.

01:24

When we go into simulate.

01:25

There are a couple of different display options that we want to toggle.

01:28

First note that in the tool section we can change to display the tool holder,

01:33

just the shaft and the flute or the flute by itself.

01:36

We can also determine whether or not the tool is

01:38

transparent and if it's going to the programmed point,

01:41

we can see the programmed point is at the center of the tool.

01:44

This is important to note,

01:45

especially if you're using in control or where or inverse where

01:50

next we can determine whether or not we want to display the tool path.

01:53

This can show just the tail of the tool path or the section just after the tool motion

01:57

or we can have it displayed before after for

02:00

the entire operation or all the tool path.

02:03

In this case I'm going to turn the tool

02:04

path off because with adaptive tool path motions.

02:07

The screen can get a little busy

02:09

for stock. We have a couple of different colorization options.

02:12

The comparison option will allow us to see stock that's been machine

02:16

down to the part as green stock that's been left behind and

02:20

still needs to be removed as blue and stock that's been gouged

02:23

or too much material has been removed will be displayed as red.

02:26

You can also change this to change color based on

02:30

the tool the operation or show just a single material.

02:33

We're going to be using the comparison option as it

02:35

does open up a couple of other options for us.

02:38

We have an accuracy slider that will help us

02:40

determine how accurate the simulation is going to be.

02:44

The further to the right, the more accurate the simulation will be however,

02:48

that will come at the cost of time,

02:49

will take more time to calculate especially complex tool paths.

02:53

We can determine whether or not the stock is shown as transparent.

02:56

We can stop on a collision and we can also

02:59

turn on leftover stock when we're using stock comparison.

03:03

We also have a tolerance value and the tolerance value in the leftover stock

03:07

can be used to make sure that you are machining accurately on your parts

03:12

as we scroll down. Also note there's a view section with model and tool.

03:17

There is a third option when we're using a machine simulation but for this

03:21

instance we have the viewpoint of the model or the

03:24

viewpoint of the tool and this will determine whether or

03:26

not the tool is moving around the part or if

03:29

the part is moving in the tool is staying stationary.

03:31

When we use machine simulation.

03:33

The tool will move up and down in Z and the part will move in X and Y.

03:37

The last option we have here is model opacity.

03:41

We can determine the opacity of the model which can help if we're using fixed during

03:45

such as this Vice.

03:47

There are other tabs such as info and statistics that can give us a bit

03:50

more information about the specific tool path or

03:53

set of tool paths that we're simulating.

03:55

For example, this case we have a machining time of about a minute for one operation.

03:60

The information tells us the current X, y and z position the spindle speed,

04:04

the feed rate as well as the operation that's on

04:08

Notice that there is a machine option in here as well, showing that we're using the

04:12

VF one.

04:13

Let's go ahead and play through.

04:15

There are a couple of different ways in which we can play tool paths.

04:18

Infusion 360 simulation

04:20

at the very bottom,

04:21

there's a green bar and we can pick or drag

04:23

to different locations to see the material that's being removed.

04:27

We can also use the play head to play through the material removal.

04:30

This allows us to jump ahead or behind

04:33

two different operations or the entire simulation.

04:36

We can also hold down the left mouse button anywhere in the canvas and drag it

04:40

to the right to move forward or drag it to the left to move backward.

04:44

In this example let's go ahead and play through.

04:47

But we're going to slow the speed down a little bit.

04:48

We want to see what happens when we get to

04:51

the section where it's removing material right in the middle

04:53

and we can see that this is potentially a bad situation because we have

04:57

material in the center and the tool just goes through it in one swipe.

05:01

This means we're going to have a large tool load as the tool gets to that area.

05:05

This means that we should potentially use a smaller tool

05:08

to clear out that area before our finishing tool paths.

05:11

You can also see it treats this as two separate pockets

05:14

moving from one side to the other

05:16

simply because the tool cannot fit through the center

05:19

at this point, let's go ahead and exit the simulation and select the entire setup.

05:24

I'm going to use the actions and simulate with machine so we can

05:27

take a look at what this looks like on the machine itself.

05:31

Once again, you can see that all of our settings are the same.

05:34

We've got our machine opacity turned down so that the vice

05:38

is shown with an opacity reduced from its normal amount.

05:41

And as we play through the simulation,

05:44

let's slow the speed down and watch the tool moving up and down in Z.

05:48

And then the table is moving in X and Y.

05:51

This is how it would work on an actual vertical mill.

05:54

So this can be helpful to simulate the entire process and make sure that

05:58

you are removing material efficiently and that

06:00

everything is moving within its confined spaces.

06:05

As we speed this up.

06:06

We can see the adaptive motion does move the tool around quite a bit.

06:10

When we get to the point where we drill and tap,

06:12

we can see that the insides of the holes are red

06:15

and that's because the model was created with the tap hole diameter

06:19

of 0.0.201 and we tapped it with a quarter 20 tap.

06:23

When you're drilling these holes,

06:24

you are drilling a smaller value that's used for those taps.

06:27

Also note in the corners,

06:29

the champers were not able to completely remove the material in

06:32

those corners or when it got around these larger bosses.

06:36

And again, this is a product of the tool.

06:38

So if we jump back in operation and we go to our deeper operation,

06:42

one thing that we can do is we can see how the tool is going to move around the part.

06:47

Once again holding down the left mouse button,

06:49

we can move through and we can see that the tool gets to a certain area and

06:53

it has to jump around because it's not able to get all the way into those corners.

06:57

So this is a good way for us to tell whether or not we need to pick

07:00

a different tool for that tool path and whether

07:03

or not the geometry is going to be acceptable

07:06

at this point,

07:07

let's go ahead and exit the simulation and take a look at one more thing.

07:11

Each tool path is going to have associated metadata with it,

07:14

it's going to allow us to see how far it's traveling when it's

07:17

feeding when it's rapid and how long the cut is expected to take.

07:21

If we right click on the operation, we can take a look at the machining time.

07:26

This will tell us that this first operation for facing is going to go approximately

07:30

a distance of 13" and it's going to take a total of 20 seconds.

07:34

We can also see that the total tool time change

07:37

is zero because we only have a single operation selected,

07:40

it's not expected to make a tool change as we go to

07:43

our adaptive tool path and take a look at the machining time.

07:46

We can see it's going 115" and a total fee time of one minute and 36 seconds.

07:52

We can change some of the values at the very top of this. Such as the feed scale.

07:56

If you create a tool path and tested on your machine and note that

07:60

the amounts that you see in fusion 360 are a little bit off.

08:03

For example,

08:04

if this tool path was to take a minute we could increase our feed

08:08

speed and we can get this a little bit closer to the actual values.

08:12

So that way your machining time better represents what your machine can do.

08:17

This is also a good reason why you want

08:19

to use data simulated inside of a machine configuration,

08:22

you can determine how fast the machine can feed in X and Y,

08:26

how fast it can feed and Z and what your feet and rapid movements are going to be

08:31

at this point.

08:32

remember that if you select the entire set up an operation,

08:35

you can get machining parameters,

08:37

such as the machining time for the entire program,

08:40

and you can also simulate the entire program with or without the machine.

08:44

Let's go ahead and make sure that we do save this before moving on to the next step.
