Rotary position drilling and tapping

00:02

In this lesson, we'll look at rotary position drilling and tapping.

00:07

After completing this lesson, you'll be able to use tool orientation and create drilling and tapping operations.

00:15

In Fusion 360, we want to carry on with our three plus one data set.

00:19

We've already created a 2D pocket and a 2D contour for one of the positions.

00:25

Now that we have this information created, we want to use it to create drilling and tapping operations for that same hole.

00:33

So I want to make sure that I repurposed this information and in this case, the tool orientation specifically.

00:41

So I'm going to start by taking my 2D contour.

00:44

I'm going to right click, and I'm going to create a Derived operation.

00:48

We're going to use drilling and select drill.

00:52

First, we need to select an appropriate tool.

00:55

We're going to go to our multi-axis library and select tool number one which is a spot drill.

00:59

We use it with aluminium finishing data, and then we'll move on to our geometry.

01:05

In this case, our tool orientation is still correct.

01:09

You can see that the Z coordinate system is pointing through the hole.

01:13

But because we went from a 2D contour operation to a drilling operation, the selection was automatically removed.

01:20

We can select based on faces or we can use selected points or diameter range.

01:28

We want to avoid using a diameter range because it'll grab all the holes on the part.

01:33

So in this instance, we'll use the selected face option.

01:37

From the heights, we need to make some adjustments because we're going to start by spot drilling,

01:41

and we don't want the tool to go all the way into the part.

01:45

So what I'm going to do is instead of using the whole bottom for the bottom height,

01:49

I'm going to use the whole top, and I'm going to say drill tip through bottom.

01:54

This will allow me to use the spot drill to simply go in and center on that hole.

01:59

The cycle will automatically be drilling and wrap it out, and we'll carry on using that as the option.

02:05

Now we've got our spot drill position, I can right click and instead of creating a Derive, I can simply duplicate this operation.

02:13

The duplicate will have all the exact same settings, so I simply need to go in and make some edits.

02:19

This is a quarter 20 whole.

02:21

So we'll start by selecting a number seven drill, which is a .201.

02:28

For our geometry, everything is still the same because we selected the whole face but now for heights, the bottom is going to be the whole bottom.

02:38

In this case, we want the drill tip to go through but we might want a little additional clearance.

02:44

So I'm going to add an additional .1.

02:48

For our cycle, instead of using drilling and rapid out,

02:51

we're going to allow it to do a chip breaking cycle which will allow to make small incremental depth changes,

02:57

and then it will retract slightly to help clear out some of the chips.

03:02

We'll say okay, and now we've created that drilling operation.

03:06

The last thing that we need to do is tap the whole.

03:09

So once again, I'll duplicate the operation, and then I'll edit.

03:14

Instead of using our drill bit.

03:16

Now we want to go to our multi-axis library, and we want to select a quarter 20 tap.

03:22

When we do that, the whole is still going to be the same but I want to go to our cycle and make sure that I'm using a tapping cycle.

03:29

It's going to be important that we use a tapping cycle because it's going to reduce the feed rate, and also it will reverse back out of the hole.

03:38

So now we've created our spot drilling operation, our chip breaking operation and our tapping operation.

03:46

So all of these have been done using a three plus one or a four-axis positioning type of operation.

03:53

From here, let's make sure that we save this before moving on to the next step.
