In this lesson, we'll create a multi-axis position operation.
00:07
After completing this lesson, you'll be able to use tool orientation and create a 3+2 milling and drilling operation.
00:16
For this lesson, we want to get started with the supply data set 3+2.f3D.
00:22
This already has a setup created with stock and the coordinate system is set inside of the pocket of this part.
00:30
So the stock on this part is assuming that the part has already been premade and turned.
00:36
However, we need to take care of these counter bores and drilling and tapping these holes.
00:41
We're going to be taking a look at this from the point of view of having a machine with dynamic work offset.
00:48
When we have dynamic work offset, that means that the center of rotation or at least the coordinate system we're setting can be anywhere on our part.
00:57
When we're dealing with a machine that the controller does not have a dynamic work offset mode,
01:02
that means that we need to set our WCS location at the center of rotation for that machine.
01:09
So this is a big distinction in how you set up your part, and this is why our coordinate system can be located inside of the pocket of this part,
01:17
as opposed to well below it at the center of rotation for the specific machine.
01:23
Now that we have our part setup, we want to get started by creating operations to first bore these pockets.
01:31
Then we want to drill and tap these holes.
01:34
We're going to start with a 2D pocket operation.
01:38
We need to select our tool, and in this case in our multi-axis tool library, we're going to be using our quarter inch flat end mill.
01:46
This is going to be tool number six, and we're going to use it for aluminium roughing.
01:53
We then need to move on to our geometry and before we actually select any geometry, we want to make sure that we use tool orientation.
02:02
When we're using tool orientation, we have the origin at our setup WCS origin.
02:07
This means that any rotation or translation that happens keeps the WCS location the same,
02:14
and simply rotates the coordinate system to match whatever part we're machining.
02:19
So for this our Z axis is going to be based off of this face.
02:23
Notice how it tilts a coordinate system in this case, rotating it about why and making sure that we have it set up,
02:32
so that way Z is pointing directly at our whole.
02:36
If we look at this from a top view, you can see how Z is pointing in the same direction as a whole,
02:42
which means that it's rotated its coordinate system about the other axis.
02:47
Now that we have it set up, we can select our geometry.
02:52
Once we have our pockets selected, I'll move on to our passes,
02:55
and I'm going to disable stock to leave, allowing it to create a finishing pass and completely machine this pocket.
03:04
Now we have our preview, you can see that we've machine that section.
03:07
I'm going to go ahead and drill and tap.
03:10
Now, drilling and tapping also needs to have the same coordinate system setup.
03:15
To do this, I'm going to create a derive based on our 2D pocket since they already set up my coordinate system.
03:22
So we'll right click, create derive.
03:24
And in this case, we will use a drilling operation to spot drill the hole.
03:29
We'll need to select our tool.
03:30
Once again going into our multi-axis library, we're going to select tool number one.
03:36
We need to select our hole and in this case, it's going to be the inside face but we're going to reset our height.
03:42
The bottom of the hole is actually going to be the top, and I'm going to allow the tip to go through which will let me spot the position on the whole.
03:52
I'm not going to pre drill this hole.
03:53
I'm simply going to go ahead and duplicate drill one, and I'm going to increase the drill that size to the appropriate size.
04:02
Once it's recalculated, I can edit the operation and select the right tool.
04:07
Inside of our multi-axis tools, we're going to go and find tool number three which is a 2764th drill bit.
04:15
And this is the drill that we need for tapping our half by 13.
04:20
I'm going to change the heights, so that the whole is now set to the whole bottom.
04:24
And because this is a blind hole, I'm not going to take the drill tip through the bottom.
04:29
I am, however, going to change the cycle to be a chip breaking partial retract.
04:37
Once we've drilled the hole, now I can duplicate this one more time, and I can create my tapping operation.
04:44
Once again after it has been duplicated, I'll edit and I'll select the appropriate tool.
04:50
Once again in our multi-axis library, we're going to go to tool number five, which is our half by 13.
04:56
The height should be the same.
04:58
However, in this case, because we are dealing with a blind hole,
05:02
I want to make sure that I have a small amount that we're going to go above the bottom of the hole.
05:08
When we're using the offset values, these are going to be positive to come up a little bit higher in the part or negative.
05:15
If we want to drill down farther when we're using drill tip through bottom, that's actually going to be a positive offset, it's reversed.
05:23
So make sure you understand which direction your tool is going.
05:26
We also need to make sure that we change the cycle to tapping.
05:31
We'll say 'okay' and allow it to tap that hole.
05:35
Now that we have our 2D pocket and our drilling operations, we can pattern this five times around the part.
05:43
We will select all the operations.
05:45
Go to New Pattern, set the pattern type to circular.
05:50
We're going to use the option for 360 degrees around a central axis, and we're going to set the number of instances to five.
05:59
We're going to allow it to order by tool and say 'okay'.
06:03
Once it's finished calculating, we can expand the pattern, and we can take a look at each operation.
06:09
If we want to, we can also take the entire setup and simulate it.
06:14
From here, we can watch it, create the machining operations to finish the pockets.
06:20
Then we can spot drill each hole, we can drill each hole and then we can tap.
06:27
One thing we will be able to notice is the bottom of the hole has a little bit of material left.
06:33
Depending on how the part was designed, it may have a flat bottom or it might have a drill tip at the bottom.
06:40
If a flat bottom is required instead of using a drill bit,
06:43
we need to go in with a smaller tool and actually bore the hole out to the appropriate size.
06:48
But in this case, we're simply looking at making sure we understand the tool orientation and how we can use that to our advantage,
06:56
when we have access to a multi-axis machine.
06:60
Now that we have everything set up, let's make sure that we save this design before moving onto the next step.
