Set the stock size

00:03

Milling is a subtractive manufacturing process

00:06

which requires removing material from a starting

00:08

block commonly referred to as stock.

00:11

In this video, we

00:13

will explore how to set up the stock for the workpiece.

00:16

When machining on a mill,

00:17

you need to start with an oversized block of material

00:20

and cut away the excess to achieve a desired shape.

00:23

This video will help you to set up a virtual stock block.

00:26

As a start to a CAM milling project,

00:29

Creation of the stock starts by right clicking on the setup icon here

00:33

and editing the parameters that you see.

00:36

Once you have the setup open,

00:37

it places this yellow translucent object around

00:39

your part which represents the solid block

00:41

of material that you will start with to machine your part in the mill.

00:45

There are many ways to establish the size

00:47

of stock which can be explored further later in

00:49

this module. One of the simplest methods will be demonstrated,

00:52

click on the stock tab and then select this option here. Relative sized box.

00:58

a straightforward method to create stock for inch [millimeter] based

01:00

parts is to make the part 1/16 of an inch [1.587 millimeters]

01:04

or 0.062" [1.587 millimeters] bigger around the sides and the top

01:08

and at least a quarter of an inch [6.35 millimeters] or 250 thousandths [6.35 millimeters] on the

01:11

bottom to give you something to hold on to in the vice

01:13

when you're cutting all the other features

01:15

on this part, to size,

01:17

All the dimensions translate to the divisions on a ruler or tape measure.

01:20

So that when you go to saw a piece of bar stock for use in the machine,

01:24

you can use a regular ruler to measure the dimensions.

01:27

You can view your overall stock size in this window here.

01:31

It's often practical to round these numbers up to equal one of the

01:34

standard dimensional sizes of bar stock

01:36

commonly available in the manufacturing industry.

01:39

Clicking OK

01:40

on the setup means it's complete and you now have material on all sides of the part

01:44

and could begin adding other items to your project.
