Select AUTOCAD 2012

Change the unit

- type “UN” then change the unit from inch to mm.

Sketch that border with size ( 100mm x 100mm )

Choose “insert” then browse your picture.

Draw the picture use “line” and “arc” based on the picture

- Use Arc to draw the picture.

Then make a “TRIM”

“Joint” all line to make one object

EDGECAM

Click “EDGECAM” icon

Open files select Option then select Preferences.

- change the unit from inch to mm.- import data/picture.

Create stock:

Select the Geometry from the menu bar.

Select the Stock Fixture option. Make sure to tick the Automatic Stock box.

In the Box Offset, set the value of X, Y and Z.

Then click OK.

Create CPL:

Select the Geometry from the menu bar.

Select the Create CPL option.

At the General tab tick the Origin box.

Then put name of CPL at the Name box.

In Plane box select <none>

Select MILL <XY> option for the Work Plane.

And for the Dimention select 2D.

Finally, click OK.

After that look at the bottom of the screen. The instruction says Digitise Origin for CPL.

So click at the end of your stock.

The CPL will be at the new origin.

Switching to Manufacture Mode:

To switch, click the Switch to Manufacture Mode icon .

Your interface will change from drawing mode to manufacture mode.

After that you will see the Machining Sequence dialog box.

You may and may not put name at the Sequence Name .

At the Discipline box choose Mill.

Choose fanuc3x.mcp at the Machine Tool box.

Make sure the Initial CPL name is the name that you use earlier.

No need to tick the Machine Datum box.

Lastly, make sure that you use Absolute at the Datum Type.

Click OK.

Cutting prosess :

Select Tooling at the menu bar.

Select Tool Store.

Choose your tool according to your project

Then click at the SELECT button.

Select MILL CYCLES at the menu bar.

At general tab:

Model type = wireframe

Mill type = climb

Strategy = concentric

NC output = feed

% step over = 50

Clean up % step over = 80

Stock type = use none or profile

Federate =250

Speed =2500 RPM

Plunge federate =100

After that depth tab, set the value needed in clearance, depth level and cut increament.

Then click OK.

Look at the bottom of the screen for further instruction.

Example using NONE as the stock type :

Digitise line / arc/continuous/curve as profile – select your object then ENTER.

Digitise containment boundry entries (return for none) then ENTER.

Example using PROFILE as the stock type.

Digitise line / arc/ continuous/ curve as profile – select your object then ENTER.

Digitise stock profile – select your stock then enter.

Digitise containment boundry ebtities (return for none) then ENTER.

Repeat the cutting process until the whole drawing is done.

Introduction CAD/CAM

Throughout the history of our industrial society, many inventions have been patented and

whole new technologies have evolved. Perhaps the single development that has impacted

manufacturing more quickly and significantly than any previous technology is the digital

computer.

Computers are being used increasingly for both design and detailing of engineering

components in the drawing office.

Computer-aided design (CAD) is defined as the application of computers and graphics

software to aid or enhance the product design from conceptualization to documentation. CAD is

most commonly associated with the use of an interactive computer graphics system, referred to

as a CAD system. Computer-aided design systems are powerful tools and in the mechanical

design and geometric modeling of products and components.

There are several good reasons for using a CAD system to support the engineering design

function:

To increase the productivity

To improve the quality of the design

To uniform design standards

To create a manufacturing data base

To eliminate inaccuracies caused by hand-copying of drawings and inconsistency

between drawings.

OBJECTIVE

To design and manufacture products

To support industry on the use various 3D CAD/CAM system.

To foster the development of high value services and to streamline product

innovation.

To create geometry drawing using AUTOCAD.

To create solid work drawing using EDGECAM.

Stimulate the tool path and operation.

THEORY

CONCLUSION

Nowadays, product can be produced by modern technology, which use computer

software, hardware and firm ware in industries. It is needed to use CAD/CAM machine to get

more accurate dimensions and irregular shape. So CAD/CAM is important in our country.

CAD/CAM has been utilized in engineering practice in many ways including drafting,

design, simulation, analysis and manufacturing. The benefits or CAD/CAM can be fully realized

only if an effective interface is established between them. Superior product can be created and

tremendous competitive advantages gained. Introduction of CAD/CAM significantly improved

of product design and manufacturing practices and production planning.

At industrial side, student will able to satisfy the employee with the skill conducting

CAD/CAM machine. Student will be able to study the software with a good condition and my

opinion there a recommendation needs to improves because all machine or pc is well in

maintenance although student is very comfort to study.
