Drill and tap in 3 axes

00:02

In this lesson, we'll drill and tap in three axes.

00:07

After completing this lesson, you'll be able to create a spot drill operation and create drilling and tapping toolpaths.

00:15

For this lesson, we want to carry on with our multi-axis positioning design.

00:19

If you had any difficulty in the setup of the adaptive the 2D contour or the 2D adaptive operations,

00:25

you can also upload the supply design, multi-axis positioning V6.F3D.

00:31

Now that we've created the 3D adaptive to clear out most of the part,

00:36

we've taken a look at the 2D contour to clear the outside of the part and then the 2D adaptive to take care of the pocket on the top.

00:44

We now want to look at making our spot drill, our drill and our tapping operations for the top four holes.

00:51

To do this, we're going to get started by going to drilling and selecting the appropriate tool.

00:57

From our multi-axis library, we want to take a look at tool number one, which is our quarter inch spot drill.

01:04

From here in the geometry section, we have several different ways we can select the holes.

01:09

We can do it by a selected face, selected points or a diameter range.

01:16

The selected face option allows us to select the face of the whole, and it'll automatically gather data about how deep the hole is.

01:24

We can use this option to also select the same diameter which will automatically grab the other three holes that are the same size.

01:32

This is a great option, especially with these blind holes where we can grab all four of the holes fairly quickly.

01:39

However, we must keep in mind that we're using a spot drill in this first operation, and we don't need to take it that deep.

01:46

So for the heights instead of using the whole bottom, we're going to take a look at a selection.

01:53

So I want to select the top, and then I'm going to use the drill tip through bottom option.

01:59

This will automatically take the tip of the drill bit,

02:02

in this case, a spot drill down far enough for it to go all the way through the bottom of our selection based on that geometry.

02:12

Also note that this opens up another option called breakthrough depth.

02:16

That breakthrough depth will allow us to add an additional amount in a positive value to go that much farther.

02:23

Because we are using the spot drill, we have to be careful with how deep we actually go down.

02:28

We might not want to use that drill tip all the way through bottom, and we might simply want to add a value, in this case -.05 enough to spot drill.

02:38

If I say okay, we take a look at the stock that's created.

02:42

We're going to go ahead and turn off our cutting moves and change our stock, so that it's not transparent anymore.

02:48

We can see exactly what material was removed.

02:52

So using that drilling and wrap it out, we can see how deep the tool went.

02:57

What we can do is make adjustments to those parameters and then determine whether or not we wanted to go down farther or maybe less.

03:05

The next thing that I'm going to do is right click on this operation and I want to duplicate it.

03:11

When we duplicate the operation, we make an exact copy,

03:14

all the settings, all the parameters that we used allowed us to grab that and simply make that duplicate.

03:22

There are other options.

03:23

For example, when we right click, we can create a derived operation.

03:28

This allows us to, for example, select drilling,

03:31

which will make a derived operation based on our selections but allow us to make adjustments such as grab a different tool.

03:39

In this case, the derive is probably the better option because we're going to be drilling with tool number 2 and number 7 drill,

03:47

and we don't want to use all of those same values.

03:50

The geometry is all the same.

03:52

Notice that we have select the same diameter but it's only grabbing that single face.

03:58

So in this case, we might need to go back and select the other faces.

04:02

For the heights, however, notice that it's grabbing the selection and in this case, I want to use whole bottom.

04:11

I'm going to turn off the offset value and reset it to zero, and then I want to go to my cycles.

04:17

In here because we are drilling a blind hole, and especially since we're going down over the diameter of the drill,

04:24

I want to make sure that I use some sort of peck drilling operation.

04:29

We have a chip breaking which is a partial retract or a deep drilling, which is a full retract.

04:34

The main difference between these is how far the tool is going to come back out for each peck that it goes down.

04:42

For the chip breaking, it's simply going to go down an amount in this case .05025,

04:48

and then it will come back up that amount and then it will drill the next step.

04:52

If we use a full retract, the drill will come all the way back out of the hole before it goes back in,

04:57

depending on what you're doing, how big of a whole you're drilling and how deep it is.

05:01

You might want the drill bit to come all the way back out to help clear those chips.

05:06

For our purposes, I'm going to go back in and that first duplicate operation I'm going to delete,

05:11

so now I have my peck drill, and then I have the drilling operation.

05:16

The next thing I want to do is create a tapping operation.

05:19

In this case, instead of creating a duplicate or a derived operation, I'm going to start again from scratch.

05:26

One of the main reasons I like to start again from scratch is because I want to make sure

05:32

that the operational defaults that come in with that tool are going to be based on that selection, and I don't have to manually change it.

05:41

So we're going to grab tool number four which is a quarter 20 tap.

05:45

For my geometry, I'm going to select the diameter range.

05:49

In this case, I can manually select based on these values,

05:53

and then for my cycle, you notice that it's automatically set to tapping based on the tool definition.

05:60

The last thing that we want to be aware of is the heights because we are dealing with the blind hole.

06:05

If we take a tap down exactly how far that blind hole has been drilled,

06:10

there's a good chance of us bottoming out and actually snapping the tap or breaking it.

06:15

So in this case, I'm going to add a positive value of .03, which will bring that tap just up a little bit.

06:24

Keep in mind the drill at the end does have a drill point, which means that the hole is going to be deeper than just .03 than this.

06:32

But again, we don't really want to take that tap all the way down to that bottom and risk breaking it.

06:38

So from here we'll say ‘okay’, and now we've created our drilling and tapping operations.

06:43

You'll notice that the preview on the screen shows that we've removed more material than the actual hole.

06:48

And that's because the hole size is based on the drill bit size which is the minimum diameter that we need.

06:54

It's not based on the maximum size that the tap would cut because we are dealing with a simplified representation of the tap.

07:02

It just looks like it's showing the major diameter.

07:05

The last thing that I want to do before I move on is I want to rename some of these operations, so that we understand what they're doing.

07:12

For adaptive one, I'm going to name this roughing.

07:16

For my 2D contour, I'm going to name this outside profile.

07:23

For my 2D adaptive, I'm going to call this top pocket.

07:28

And remember with that top pocket, we didn't have any 2D contour or pocketing finishing operations.

07:34

That's something we can certainly go back and do.

07:36

But because this course is based on multi-axis, I didn't feel the need to spend time working on 2D finishing operations.

07:44

Then for our drill 1, we're going to call the spot drill.

07:50

For drill 2, we're going to call this peck drill.

07:55

And for drill 3, we're going to call this tap.

07:60

And again based on some of those operational defaults or those parameters in your user preferences, you'll see different things.

08:07

For example, we're seeing the cycle type for rapid out chip breaking and tap inside of our browser.

08:13

These are things that we can turn on or off in our user preferences.

08:18

For now, I'm going to go back to a Home view, make sure that I do save the design, and then we can move on to the next step.
