verify tool path motion
00:06
in this video.
00:07
We'll use simulation to verify tool path
00:09
motion and will modify tool path parameters.
00:13
Infusion 3 60. Let's carry on with our engine case.
00:16
Rh ready to program at this point we've created all
00:20
of the different operations needed to program the part completely.
00:24
However inside of these operations we haven't really taken the time
00:28
to name any of the operations specific to what's going on.
00:32
So part of the process of verifying and validating your program is to make
00:37
sure that it's cleaned up and you know what's going on in each operation
00:40
as well as where the tool is moving and if you're wasting any time
00:45
so there are a few things that we do want to look at.
00:47
But first let's take a look at how we can rename the different operations.
00:51
So when we click on an operation it's going to show us the stock
00:55
that's been removed and this is based on stock that's created for in process.
01:00
Now this in process stock can be turned on and off if you want.
01:03
But it is very helpful to get a good idea of what's being removed for each tool path.
01:08
This is a great way to quickly and easily verify
01:11
what's happening but it doesn't always tell the whole story.
01:14
So the first thing that I want to do is I want to
01:16
take this facing tool path and I'm going to rename it face top.
01:22
And then for my two D. Contour I'm gonna say
01:25
contour
01:27
outside
01:29
profile
01:31
for this drilling. What we're doing is we're spotting. So we're going to do spot top
01:36
and then for this drill, what we're doing is
01:43
pre drill.
01:45
Then for our champ for what we're doing is we're
01:48
champ for
01:51
drill
01:52
and then we're championing our profile
01:57
And lastly we are tapping so 10-32 tap.
02:02
So it's very quick for us to go through and rename these operations.
02:05
But what if we want to go a step further and we want to make sure that the
02:09
tool path is actually moving correctly and we don't
02:12
have any errors or collisions that we're not expecting.
02:16
So if we select the setup we can right click and we can select simulate.
02:21
We can also find simulate from the actions menu by going down to simulate.
02:26
When we look at simulate,
02:28
we have a couple options that are displayed on the right hand side.
02:31
We can turn the tool on and off and change what's being displayed.
02:34
We can also turn the tool path on and off as well as
02:37
individual elements such as showing points
02:40
and these are where we're transitioning from
02:42
straight lines or arcs.
02:43
Or it could be where we're going from a feed to a lead or a rapid movement.
02:49
We also can do things like show the cutting moves, show the leads and show the links.
02:54
So each of these can be turned on and off to
02:56
really dive deep into what's happening with our tool path,
02:59
we can also turn the stock on and off and we have
03:02
different ways in which we can colorize the stock for example,
03:05
it can change the color based on operation based on each tool change.
03:09
Or we can turn on a comparison.
03:11
The comparison can be really helpful if you want
03:14
to verify that all stock is being removed.
03:16
There are even options that allow us to look
03:19
at leftover stock amounts and add a tolerance value.
03:22
So if we're roughing apart and we want to make sure that we don't have any gouges,
03:26
we can set the stock value to our .02 stock to leave from here.
03:31
We can also turn on opacity of the model and
03:35
we can also change the opacity of the stock.
03:38
We have an indicator at the bottom that allows us to adjust the speed.
03:42
We can jump ahead to individual operations or all the way to the
03:45
end or we can select play to watch the tool play through.
03:49
You can see that it's removing material as it goes and what we're
03:54
going to see at the very end is that the stock is going to
03:57
go all the way down to the top of our part and anything
03:60
that is down to the actual size of the part will show in green
04:04
and anything that still has stock remaining will be blue.
04:07
Anything that has cut too much material will be shown in red.
04:10
Also while we're here there's a bar at
04:13
the bottom that shows cutting movements in green.
04:15
And we can also use a cursor on the screen holding down
04:18
the left mouse button and we can manually drag through the tool.
04:21
Path movements.
04:23
I'm going to allow it to play through these operations.
04:26
You can see that it's roughing the outside and then
04:28
it comes back and cuts the outside of the part.
04:30
And if we take a look at this,
04:32
we can see that the champ for has actually gone through the model.
04:36
And the reason that the champ has gone through the model is because
04:40
we didn't have a chance for on the model to start with.
04:43
So if we want to take a look at this,
04:44
this is where the opacity of the model comes in handy.
04:47
We can reduce this down and we can make sure that we do have a nice clean cut.
04:52
You'll also note that it's red inside of the tapped holes.
04:55
And that's because when we model the tapped hole,
04:57
we're modeling the drill size for the tap,
04:60
not the overall diameter of the tapped hole.
05:02
So during simulation,
05:04
it appears as if it's removed too much
05:06
material because it's not showing the actual threats.
05:09
But that doesn't necessarily mean it's a problem. As long as this is a tapped hole
05:13
going to bring the opacity of the model back and I'm
05:16
going to take a look at my info and statistics taps
05:20
inside of info.
05:21
It can show the current position of the tool so you can
05:23
see as I'm moving the tool around it can change the position,
05:27
we can watch what's going on with things like the spindle speed
05:30
in this case it's sinking counterclockwise and clockwise
05:34
depending on the orientation of the tap.
05:37
If we're using a right hand or left hand and we can
05:39
see that the spindle speed is fixed based on that operation,
05:42
we can also get information about the machine,
05:45
but in this case we haven't selected a machine inside of our setup.
05:49
We can go to statistics and see the machining time,
05:52
the distance as well as the number of operations and tool changes so we
05:56
can see everything to machine this part right now is happening in about two,
05:60
almost three minutes.
06:02
There are other ways in which we can get some of that
06:04
information by right clicking on individual tool paths or the setup itself.
06:09
When we look in here we can see that we have a machining time option.
06:13
The machining time based on our feed scale, can show us the rapid feed,
06:18
we can show the number of seconds it takes for a tool change.
06:21
We can show the speed distance,
06:23
the total feed time and the overall machining time of our project.
06:27
Now.
06:27
This is only looking at op one where we're roughing
06:30
and finishing the top and the outside of the part.
06:33
If we find that through actual machining. These values are off.
06:37
We can adjust some of these times like the rapid
06:40
feed and we can adjust things like the feed scale.
06:43
If we set this to 150% you can see that it drops our machining time.
06:48
So this can be a great way to just verify what's going on with your program.
06:52
Now each of these has a different vice when we're looking at machining um but we can
06:58
select all the setups at the same time and we can simulate them all at once.
07:02
This can be beneficial because it does allow us to go
07:05
through each operation and make sure the entire part is machined.
07:09
However, there is a downside because all of these red lines are collisions.
07:13
Now these are not actual collisions but since we represented the vice as a fixture,
07:18
what it means is it's looking at a collision with
07:20
the fixture between either the tool or the tool holder,
07:23
I'm going to jump all the way to the end which will be through all
07:27
four operations and what we should see is that the part is completely machined.
07:31
Now, if we happen to have a stop on collision checked inside of simulate,
07:35
we would be hitting the play button quite a bit
07:38
in order to get through all of these collisions.
07:40
Now again in this case these collisions are not
07:43
real because it's colliding with the fixture and not
07:46
the actual part and you can see at the
07:48
very end everything looks to be completely machined,
07:52
We can also verify the statistics,
07:54
we can see how long it should take to machine the entire part.
07:57
Keeping in mind this does not account for changes in setup and operation.
08:03
The last thing that I want to do is take
08:05
a look specifically at operation for operation four has R.
08:09
Two D. Contour which takes care of these holes and it has our champ for at the end.
08:14
So taking a look at just operation for let's go ahead and simulate this.
08:18
I'm going to view it from this orientation and what I want
08:21
to do is I want to play through its cutting the hole here
08:26
and then the tool is going to come up away from the part,
08:28
move over and back down to create the other cut.
08:31
Now when we take a look at this.
08:33
Some things that we want to consider now it doesn't currently appear that
08:37
the drill bit from the other operation came all the way through.
08:41
So what that means is even though we gave it a pre drill location,
08:45
it is actually just going directly down into that hole.
08:49
Now that is obviously going to produce a problem.
08:52
And the reason for that is because when we told it to go down to the end
08:55
of the whole it assumes the end of the hole is where the counter war starts.
08:59
So this is one setup that we need to make sure that we adjust.
09:03
The other thing that we can fix is that the tool is going up
09:06
above the part and moving over and wasting quite a bit of time.
09:10
So inside of the two D.
09:11
Contour operation we can go and edit our heights and when
09:15
we take a look at this again from the side,
09:17
what we're looking at is going to be our feed and retract heights.
09:20
So instead of 20.2 I'm going to set these relatively low at point oh five and I'm going
09:26
to set this low at point oh five and the top height right now is set to zero.
09:31
And we'll say okay
09:32
when we regenerate this it brings down a rapid movements
09:36
just a little we can continue to modify these values to
09:39
save a little bit of time but for a relatively small
09:41
part the time savings are going to be very minimal.
09:44
But it is important that we do go back and
09:47
we fix the operation where we drill that hole.
09:50
So let's activate operation three and let's find the
09:53
drilling operation that was used to drill those holes.
09:56
When we take a look at this we can see that we have tool number seven which is
10:00
drilling all the way through these holes and it indeed does not go all the way down.
10:05
What we want to do is we want to modify
10:07
this tool path and inside of our whole selection,
10:10
we're going to auto merge whole sections and you can
10:13
see in this case it doesn't actually auto merge here.
10:16
So instead of using this option,
10:18
Because all of the holes should end at the same height,
10:22
what we're going to do instead of using whole bottom,
10:24
what we're going to do is go to the bottom of the
10:28
model and once we go to the bottom of the model,
10:30
we can include a breakthrough depth, unlike the offset value, which is negative,
10:34
the breakthrough depth is going to be a positive value.
10:37
So we're going to set this 2.05, say okay and allow it to recalculate that.
10:43
Now, if we go back to op four,
10:45
we activate this and we go back and simulate it one more time,
10:49
we can see that there are now pre drilled holes here.
10:52
So if we go through, we're no longer plunging directly into the stock,
10:55
but we are now moving into an opening,
10:57
we're taking a quarter inch tool into a 0.257 hole.
11:01
So it should be able to just plunge down into that area without any problems.
11:06
But sometimes you might want to consider doing something else
11:08
like helix or a rapid ramp entry into that hole
11:14
at this point, let's go ahead and close our simulation.
11:17
Let's make sure that we do save this and move on to the next step
Video transcript
00:02
verify tool path motion
00:06
in this video.
00:07
We'll use simulation to verify tool path
00:09
motion and will modify tool path parameters.
00:13
Infusion 3 60. Let's carry on with our engine case.
00:16
Rh ready to program at this point we've created all
00:20
of the different operations needed to program the part completely.
00:24
However inside of these operations we haven't really taken the time
00:28
to name any of the operations specific to what's going on.
00:32
So part of the process of verifying and validating your program is to make
00:37
sure that it's cleaned up and you know what's going on in each operation
00:40
as well as where the tool is moving and if you're wasting any time
00:45
so there are a few things that we do want to look at.
00:47
But first let's take a look at how we can rename the different operations.
00:51
So when we click on an operation it's going to show us the stock
00:55
that's been removed and this is based on stock that's created for in process.
01:00
Now this in process stock can be turned on and off if you want.
01:03
But it is very helpful to get a good idea of what's being removed for each tool path.
01:08
This is a great way to quickly and easily verify
01:11
what's happening but it doesn't always tell the whole story.
01:14
So the first thing that I want to do is I want to
01:16
take this facing tool path and I'm going to rename it face top.
01:22
And then for my two D. Contour I'm gonna say
01:25
contour
01:27
outside
01:29
profile
01:31
for this drilling. What we're doing is we're spotting. So we're going to do spot top
01:36
and then for this drill, what we're doing is
01:43
pre drill.
01:45
Then for our champ for what we're doing is we're
01:48
champ for
01:51
drill
01:52
and then we're championing our profile
01:57
And lastly we are tapping so 10-32 tap.
02:02
So it's very quick for us to go through and rename these operations.
02:05
But what if we want to go a step further and we want to make sure that the
02:09
tool path is actually moving correctly and we don't
02:12
have any errors or collisions that we're not expecting.
02:16
So if we select the setup we can right click and we can select simulate.
02:21
We can also find simulate from the actions menu by going down to simulate.
02:26
When we look at simulate,
02:28
we have a couple options that are displayed on the right hand side.
02:31
We can turn the tool on and off and change what's being displayed.
02:34
We can also turn the tool path on and off as well as
02:37
individual elements such as showing points
02:40
and these are where we're transitioning from
02:42
straight lines or arcs.
02:43
Or it could be where we're going from a feed to a lead or a rapid movement.
02:49
We also can do things like show the cutting moves, show the leads and show the links.
02:54
So each of these can be turned on and off to
02:56
really dive deep into what's happening with our tool path,
02:59
we can also turn the stock on and off and we have
03:02
different ways in which we can colorize the stock for example,
03:05
it can change the color based on operation based on each tool change.
03:09
Or we can turn on a comparison.
03:11
The comparison can be really helpful if you want
03:14
to verify that all stock is being removed.
03:16
There are even options that allow us to look
03:19
at leftover stock amounts and add a tolerance value.
03:22
So if we're roughing apart and we want to make sure that we don't have any gouges,
03:26
we can set the stock value to our .02 stock to leave from here.
03:31
We can also turn on opacity of the model and
03:35
we can also change the opacity of the stock.
03:38
We have an indicator at the bottom that allows us to adjust the speed.
03:42
We can jump ahead to individual operations or all the way to the
03:45
end or we can select play to watch the tool play through.
03:49
You can see that it's removing material as it goes and what we're
03:54
going to see at the very end is that the stock is going to
03:57
go all the way down to the top of our part and anything
03:60
that is down to the actual size of the part will show in green
04:04
and anything that still has stock remaining will be blue.
04:07
Anything that has cut too much material will be shown in red.
04:10
Also while we're here there's a bar at
04:13
the bottom that shows cutting movements in green.
04:15
And we can also use a cursor on the screen holding down
04:18
the left mouse button and we can manually drag through the tool.
04:21
Path movements.
04:23
I'm going to allow it to play through these operations.
04:26
You can see that it's roughing the outside and then
04:28
it comes back and cuts the outside of the part.
04:30
And if we take a look at this,
04:32
we can see that the champ for has actually gone through the model.
04:36
And the reason that the champ has gone through the model is because
04:40
we didn't have a chance for on the model to start with.
04:43
So if we want to take a look at this,
04:44
this is where the opacity of the model comes in handy.
04:47
We can reduce this down and we can make sure that we do have a nice clean cut.
04:52
You'll also note that it's red inside of the tapped holes.
04:55
And that's because when we model the tapped hole,
04:57
we're modeling the drill size for the tap,
04:60
not the overall diameter of the tapped hole.
05:02
So during simulation,
05:04
it appears as if it's removed too much
05:06
material because it's not showing the actual threats.
05:09
But that doesn't necessarily mean it's a problem. As long as this is a tapped hole
05:13
going to bring the opacity of the model back and I'm
05:16
going to take a look at my info and statistics taps
05:20
inside of info.
05:21
It can show the current position of the tool so you can
05:23
see as I'm moving the tool around it can change the position,
05:27
we can watch what's going on with things like the spindle speed
05:30
in this case it's sinking counterclockwise and clockwise
05:34
depending on the orientation of the tap.
05:37
If we're using a right hand or left hand and we can
05:39
see that the spindle speed is fixed based on that operation,
05:42
we can also get information about the machine,
05:45
but in this case we haven't selected a machine inside of our setup.
05:49
We can go to statistics and see the machining time,
05:52
the distance as well as the number of operations and tool changes so we
05:56
can see everything to machine this part right now is happening in about two,
05:60
almost three minutes.
06:02
There are other ways in which we can get some of that
06:04
information by right clicking on individual tool paths or the setup itself.
06:09
When we look in here we can see that we have a machining time option.
06:13
The machining time based on our feed scale, can show us the rapid feed,
06:18
we can show the number of seconds it takes for a tool change.
06:21
We can show the speed distance,
06:23
the total feed time and the overall machining time of our project.
06:27
Now.
06:27
This is only looking at op one where we're roughing
06:30
and finishing the top and the outside of the part.
06:33
If we find that through actual machining. These values are off.
06:37
We can adjust some of these times like the rapid
06:40
feed and we can adjust things like the feed scale.
06:43
If we set this to 150% you can see that it drops our machining time.
06:48
So this can be a great way to just verify what's going on with your program.
06:52
Now each of these has a different vice when we're looking at machining um but we can
06:58
select all the setups at the same time and we can simulate them all at once.
07:02
This can be beneficial because it does allow us to go
07:05
through each operation and make sure the entire part is machined.
07:09
However, there is a downside because all of these red lines are collisions.
07:13
Now these are not actual collisions but since we represented the vice as a fixture,
07:18
what it means is it's looking at a collision with
07:20
the fixture between either the tool or the tool holder,
07:23
I'm going to jump all the way to the end which will be through all
07:27
four operations and what we should see is that the part is completely machined.
07:31
Now, if we happen to have a stop on collision checked inside of simulate,
07:35
we would be hitting the play button quite a bit
07:38
in order to get through all of these collisions.
07:40
Now again in this case these collisions are not
07:43
real because it's colliding with the fixture and not
07:46
the actual part and you can see at the
07:48
very end everything looks to be completely machined,
07:52
We can also verify the statistics,
07:54
we can see how long it should take to machine the entire part.
07:57
Keeping in mind this does not account for changes in setup and operation.
08:03
The last thing that I want to do is take
08:05
a look specifically at operation for operation four has R.
08:09
Two D. Contour which takes care of these holes and it has our champ for at the end.
08:14
So taking a look at just operation for let's go ahead and simulate this.
08:18
I'm going to view it from this orientation and what I want
08:21
to do is I want to play through its cutting the hole here
08:26
and then the tool is going to come up away from the part,
08:28
move over and back down to create the other cut.
08:31
Now when we take a look at this.
08:33
Some things that we want to consider now it doesn't currently appear that
08:37
the drill bit from the other operation came all the way through.
08:41
So what that means is even though we gave it a pre drill location,
08:45
it is actually just going directly down into that hole.
08:49
Now that is obviously going to produce a problem.
08:52
And the reason for that is because when we told it to go down to the end
08:55
of the whole it assumes the end of the hole is where the counter war starts.
08:59
So this is one setup that we need to make sure that we adjust.
09:03
The other thing that we can fix is that the tool is going up
09:06
above the part and moving over and wasting quite a bit of time.
09:10
So inside of the two D.
09:11
Contour operation we can go and edit our heights and when
09:15
we take a look at this again from the side,
09:17
what we're looking at is going to be our feed and retract heights.
09:20
So instead of 20.2 I'm going to set these relatively low at point oh five and I'm going
09:26
to set this low at point oh five and the top height right now is set to zero.
09:31
And we'll say okay
09:32
when we regenerate this it brings down a rapid movements
09:36
just a little we can continue to modify these values to
09:39
save a little bit of time but for a relatively small
09:41
part the time savings are going to be very minimal.
09:44
But it is important that we do go back and
09:47
we fix the operation where we drill that hole.
09:50
So let's activate operation three and let's find the
09:53
drilling operation that was used to drill those holes.
09:56
When we take a look at this we can see that we have tool number seven which is
10:00
drilling all the way through these holes and it indeed does not go all the way down.
10:05
What we want to do is we want to modify
10:07
this tool path and inside of our whole selection,
10:10
we're going to auto merge whole sections and you can
10:13
see in this case it doesn't actually auto merge here.
10:16
So instead of using this option,
10:18
Because all of the holes should end at the same height,
10:22
what we're going to do instead of using whole bottom,
10:24
what we're going to do is go to the bottom of the
10:28
model and once we go to the bottom of the model,
10:30
we can include a breakthrough depth, unlike the offset value, which is negative,
10:34
the breakthrough depth is going to be a positive value.
10:37
So we're going to set this 2.05, say okay and allow it to recalculate that.
10:43
Now, if we go back to op four,
10:45
we activate this and we go back and simulate it one more time,
10:49
we can see that there are now pre drilled holes here.
10:52
So if we go through, we're no longer plunging directly into the stock,
10:55
but we are now moving into an opening,
10:57
we're taking a quarter inch tool into a 0.257 hole.
11:01
So it should be able to just plunge down into that area without any problems.
11:06
But sometimes you might want to consider doing something else
11:08
like helix or a rapid ramp entry into that hole
11:14
at this point, let's go ahead and close our simulation.
11:17
Let's make sure that we do save this and move on to the next step
