1.0 INTRODUCTION
Students will be exploded to the utilization of CAD/CAM software during the
laboratory training. The CAD software used is the Inventor Professional Version 2008,
while the CAM software is MasterCAM V8 (Version 8). A series of training will be
given for each main and basic function of these software.
Autodesk Inventor, developed by U.S.-based software company Autodesk, is a
3D mechanical solid modeling design software for creating 3D digital prototypes used
in the design, visualization and simulation of products.
Mastercam’s comprehensive set of predefined toolpaths—including contour, drill,
pocketing, face, peel mill, engraving, surface high speed, advanced multiaxis, and
many more—enable machinists to cut parts efficiently and accurately. Mastercam
users can create and cut parts using one of many supplied machine and control
definitions, or they can use Mastercam’s advanced tools to create their own
customized definitions.
2.0 THEORY
Students will be learning the basic usage and general function of Inventor Professional
2008 in order to design a solid object from 2D sketching to 3D modeling. Next, the
solid model.ipt file is then projected onto the 2D detail drawing via the
Autodesk/AutoCAD drawings file, “.dwg” format. Convertion of the “.ipt” file
(Inventor part file) into other standardized formats such as STEP, IGES, and SAT is
introduced as a neutral interchange for other system of CAD/CAM software in future.
Secondly, the solid model drawn from the Inventor is imported as SAT format
into MasterCAM for tool paths generation, machining process simulation and
verification. Finally, the numerical control codes generated from MasterCAM is
posted as .nc file which can be inserted into CNC machines as machining program
codes.

3.0 OBJECTIVES
( I ) To learn the basic usage and functions in order to design solid modeling
by using Inventor Professional 2008 software.
( II ) To learn to use MasterCAM software in order to plot machining tool paths,
doing machining simulation and verification, and post NC codes generated.
4.0 EQUIPMENTS AND TOOLS
( I ) Personal Computer
( II ) Autodesk Inventor Professional 2008 software
( III ) MasterCamV8 software
5.0 PROCEDURE

( Design and draw a solid object )
( II ) CAM - MasterCamV8 software
( Machining the designed solid object )

5.1 CAD – Autodesk Inventor Professional 2008
1. Open New part file namely “standard(mm).ipt in metric unit
( File > New > Metric > Standard(mm).ipt > OK )
2. Construct a scout logo shape in 2D sketch by using the commands such as line,
center point circle, two point rectangular three point arc and general dimension.
4
3. By clicking the “Return” button after finish sketching, then press F6 to see
isometrcic view. Extrude the shape by 2mm.
4. Set a work plane as shown in the figure , use the mirror command to form
another side of the of the half-shaped logo.
5
5. Sketch and extrude the shape that has been drawn by 1mm.
6
6. Sketch and locate the “star” by using the command : polygon, center point circle,
line and general dimension. Extrude the shape that has been drawn by 1mm.
Afterwhich, use mirror command to construct another similar shape at the left
side with the aid of working plane.
7
7. Sketch at circle and extrude it by 5mm to cut away the selected part to form a
hole. The hole is to put a chain to make this scout logo plate as a keychain.
8. Finally, the product ( keychain ) is being constructed.
8
9. Save the file as type “ .ipt ” . ( File > Save As )
10. Meanwhile, Save another file as type “ .SAT ” , so that it can be opened at
MasterCam X ( File > Save Copy As )
9
11. Open another new drawing file : ANSI(mm).idw
12. Projecting the solid model into 2D orthogonal drawings by clicking the base view,
then select and open the saved file.
10
13. Select the appropriate scale ( 4:1 ) and key-in the label name ( Front View ).
Click on the light bulb to display them on screen. Select the orientation ( bottom )
14. Click “Projected View” then select the front view and drag it on top left corner,
top right corner and bottom right corner to form Top View, Isometric View and
Side View.
11
15. Right Click the any of the view then select “Retrieve Dimension” or manually
construct the dimension using the Drawing Annotation Panel.
16. The Dimension is displayed as shown in figure
12
17. Modify the block title and detail by clicking the “iProperties”
( File > iProperties )
18. Finally the drawing view is completed as shown. Save the file as “ .idw.”

5.2 CAM – Mastercam V8
1. Impoet the saved file type “ .SAT ” into the MasterCam X4.
2. Convert it into “ .MC8” by saving a new copy so that it can be opened in
MasterCam V8
15
3. Open saved file type “.MC8” in MasterCam V8. ( Main Menu > File > Get )
4. Click the icon “Screen-Surf Disp-shading ”( an earth ) and select shading active
to view the drawing in solid. Set the current configuration file as metric unit.
( Main Menu >Screen > Configur )
16
5. Set up the stock to be machined by creating a bounding box.
( Main Menu > Toolpaths >Job Setup > Bounding box > Window > Done )
6. Create a contour tool paths around part. Use chain to select outer border.
( Main Menu > Toolpaths > Contour > Chain > End here > Done )
