Create custom hole sizes with the Bore toolpath

00:04

The drill tool path and use of drill bits can be used to generate holes.

00:07

The exact size of any drill bits you have on hand.

00:10

But for custom sizes or for larger holes,

00:13

the bore tool path is the best choice you can make not just for

00:15

simplicity but also to create a hole that is more cylindrical and precise.

00:23

If you need to create a hole of non-standard size

00:26

One of the easiest ways to accomplish this is

00:27

to use the bore tool path found right here.

00:30

This tool path uses an end mill smaller than

00:32

the desired hole and spirals the tool into the hole

00:36

to cut the hole to desired finished size.

00:39

Select the bore tool path in the 2D machining tab

00:42

and identify which tool you want to work with. For our project.

00:45

We'll use the three quarter inch [18 millimeter]

00:46

endmill to bore this large circle here to final size,

00:54

Select the hole and verifying the height tab

00:57

that you're cutting all the way to the bottom of the hole.

01:00

Also, please

01:02

make sure when using this machining strategy that

01:04

the flute length of the end mill needs to

01:06

be longer than the bore depth or the tool

01:08

must have a reduced shank of appropriate depth.

01:12

It is important to understand that this process works best with center cutting

01:15

end mills and it can also be used to rough and finish,

01:18

cut a hole.

01:18

At the same time.

01:20

If you wanted to rough the whole first, using the bore tool path,

01:23

you would likely engage the stock to leave feature

01:26

and run the roughing operation.

01:27

First,

01:28

followed by a second operation with the stock to leave turned off

01:32

to provide a better final surface finish and a smoother cut.

01:38

You can also adjust the infeed angle for a gentler or a more aggressive cut.

01:42

But the two degree default tends to work just fine.

01:46

This parameter controls how steeply the cutter is spiraled into the hole.

01:50

An increased angle will speed up the process

01:55

and a decreased one will improve the surface finish.

02:00

The bore tool path is a great way to generate holes

02:02

that are not the diameter of the stock drill bits.

02:05

And the resulting holes have the advantage of being

02:06

straighter and more cylindrical than their drill only.

click, ok. When you finish the process

02:13

and verify your results, using the simulation tool.
