In this video, we'll create internal grooving and tapping toolpaths.
00:06
After completing this step, you'll be able to create a single groove and tap a hole.
00:12
In Fusion 360, we want to carry on with our CAD CAM Lathe dataset.
00:17
The last operation we have is an internal boring toolpath and this is going to allow us to get in and cut the internal groove.
00:24
Before we go much further, I'm going to go to inspect and section analysis and create a new section analysis based on one of the default origins.
00:32
Going to use the XZ plane and say, okay.
00:36
This helps us look inside the part and makes the selection process a little bit easier.
00:41
Now we're going to go to turning and we want to select single groove.
00:46
We need to select an appropriate tool. So we'll go to our introduction to CAD CAM dataset and select ID grooving.
00:53
Once we select it will need to make sure that the mode and direction is set to inside grooving.
00:59
Next we're going to go to our geometry section and grab the back edge of the internal groove.
01:05
We then want to change the groove alignment to back and we want to move on to our radii.
01:13
I want to make sure that the tool knows exactly how much material has been removed and how much material is left inside.
01:20
So for my retract plane, it's set to clearance and my clearance plane is based on the stock, ID -10 mm.
01:27
Instead, I'm going to use this selection. I'm going to grab the inside diameter.
01:33
This gives us a little bit more clearance and you notice that this is set to -10 mm right now.
01:39
If we set it to 0, notice that it's still displaying as red.
01:44
When it's displayed as red, it's telling us that the clearance radius must be below the inner radius.
01:50
The inner radius right now is defined as the stock ID which was 0.
01:56
So once again we use the selection and then the clearance value. We can use that -10 mm which gives us a little bit more room.
02:05
For our passes, we have a couple options here but I'm going to create the toolpath first and then we'll explore some of the options.
02:12
Let's go ahead and say okay, and let's minimize the models and our browser and note that our tool is displayed as red.
02:18
The preview is showing that we're removing too much material because the size of the tool is just too large for what we need.
02:25
So let's go ahead and right click and edit the tool.
02:29
The first thing I want to do is redefine my insert.
02:32
We're going to be using the same insert type so the shape is square and the tolerance in the cross section are the same.
02:39
However, we need to modify some of the values.
02:42
For the overall length, we're going to set this at
02:49
And the corner radius is going to be custom and it's going to be set to 0 the head length,
02:57
In this case, we can leave at 3.75 and the groove width is going to be 2.7.
03:03
Next we want to move to our holder set up.
03:06
This is going to be a right handed holder as we're spinning the spindle in the same direction for all of our toolpaths.
03:12
This is an important distinction.
03:14
Obviously you can have the spindle change directions,
03:17
but if you want to continue to have it spinning while you're making your tool changes,
03:21
it's important for us to just be aware of the orientation of our tools and the direction the spin will be going.
03:28
For our cutting width we need to make some adjustments. The cut width is going to be 8 mm. Our head length is going to be reduced to 15 mm.
03:37
The overall length is going to be reduced to 75 mm.
03:43
And the shank width is going to be reduced to 5 mm.
03:48
In the setup, note that we are spinning in the clockwise direction and we'll go ahead and accept.
03:54
It changes the orientation of the tool. But now we need to select the toolpath and regenerate.
04:00
Once we regenerate, we're able to see the cut on the inside of the part and the material that's been removed.
04:08
Now that we've removed the material, we can create our internal tapping operation.
04:12
We're going to go to drilling select "Drill" and then we need to select the appropriate tool.
04:18
We're going to go to our Fusion 360 library and we need to look for a tap.
04:23
So from the filters we're going to take a look at the options that we have, tap, right hand and then we can select a specific diameter.
04:33
If I enter a value of 25 note that nothing comes up.
04:37
If I enter a smaller value such as 20 mm, you can see here that we have a few options.
04:44
I'm going to select a range and go from 20 to 25 and see if we have anything larger.
04:50
Note that we have a 24 or an M24 by 2.0.
04:55
We're going to select this even though it's not the right tool and we'll have to make some adjustments.
04:60
In the geometry section, I'm going to select the area in which we want to tap.
05:04
And then in the heights section we're going to go to a front view and note that it's going to be going to the whole bottom based on our selection.
05:12
If we want to have an offset we can enter a negative value.
05:16
In this case, I'm going to enter a negative 2 mm and that'll let the tool go a little bit further.
05:23
The next thing that we want to do is we want to modify our tool to be the right size.
05:28
In this case let's expand this and let's right click and edit our tool.
05:32
First, I'm going to go to the post processor and adjust this to be tool number 11 and I'm going to disable live tool.
05:39
I need to synchronize the tool motion and the spindle direction.
05:42
So it's important that the spindle direction and speed is coming from the spindle on the machine and not any life tooling in this case.
05:51
Next we're going to take a look at the Qatar definition. Right now the diameter is set to 24 and we're going to increase that to 25.
05:59
We can leave the shaft diameter at 22. And all the rest of the parameters are fine.
06:03
Noting that the thread pitch is set to two, which is the same because we're using an M25 by 2.0.
06:10
We're going to accept the change and we need to select and regenerate the toolpath.
06:16
Now we've updated this based on our new tool.
06:20
At this point, let's make sure that we minimize our toolpaths and let's save the design before moving on to the next step.
