I. INTRODUCTION
Computer Aided Design (CAD)
CAD is a software tool used by engineers, architects, designers, and
drafters to create digital 2D and 3D drawings to design a variety of
items and spaces. Computer models are created and defined by
geometrical patterns. CAD allows designers to test the objects by
simulating real-world conditions. It can design anything from a
simple shampoo bottle to a complex jet plane.
Computer Aided Manufacturing (CAM)

CAM uses geometrical design data to control automated machinery.
These systems are associated with CNC or direct numerical control
(DNC) systems, in which both can mechanically encode
geometric data. The main purpose of CAM is to create a faster
production process and allow components and tools to have precise
dimensions and material consistency.
II. OBJECTIVE
1) To understand the concept of use of computers in Design and
manufacturing
2) To understand the basic design process and Product life cycle
Management
3) To develop 3D modelling Skills required for product design
4) To understand the basics of Industrial Automation
5) To understand nature & significance of NC Machine tools
6) To develop skills for programming skills required for NC
manucfuring
I. PROCEDURE
1. Open the Autodesk Inventor Pro 2023, create new file, click metric folder and then
choose the metric file.
2. Then click Start 2D Sketch and use the XZ plane to start sketching.
3. Starting point at (0,0) and then firstly sketch a rectangular with 120 length and 90
width. Then, put a point at (8,-18) and (16,-10) to make the drawing of second
rectangular easier. After that, draw the second rectangular inside the first one.
4. After finished, draw a circle with 15 radius at the both side endpoint of the second
rectangular. Then trim the unwanted part until it became arc.
5. Next, draw two line 15 cm to the right and 15 cm to the left with the point of (70.-60).
6. After that, draw lines with 150.95 degree on both side at the end of the two 15 cm
lines. Then just draw two straight line up starting at (8,-18) and (8,-102) also make
sure that the 150.95 degree line on both side overlap with the lines. So the corner can
be create using chamfer on both side with 12 radius.
7. Then, place a point at (39,-60) and draw a square with 35.4 cm width and length.
8. After that click the rotate ribbon and rotate the square using the (39.-60) as the
centerpoint with 45 degree. Then, chamfer every corner of the square with 4 radius.
9. Furthermore, extrude every layer of rectangular using the length given.

11. Moreover, start a new sketch on the center of 45 degree square hole.
12. Then draw a circle with 28 cm diameter at the (39,-60) as the centerpoint. After that,
place a point exactly below straight line at the of the circle.
14. Then, rotate the point using circular pattern with 4 point and finish sketch.
15. Furthermore, click the hole option at modify ribbon and it will automatically select all
the four point just now. Choose the countersink hole and adjust it diameter.
17. Lastly the workpiece is done.
18. Additionally, create a new file using ISO.IDW folder. Then click Base so the workpiece
will appear. Then adjust it view and scale. Use the front view to make an orthographic
view.
19. Then choose annotate ribbon and click the Ordinate. Then select the view and delete
rest of the unwanted part.
20. After that select the place view ribbon at click at the section. Select the view and the
cross section view of the workpiece will appear.
21. Finally the Practical Task is done and fill the required information in the tittle block.
II. RESULT
III. DISCUSSION
There were a couple of problems that I faced during this Practical Task. Several of them
were due to my unfamiliarity to the new interface of Autodesk Inventor Pro 2023. It took
me a little to familiarize myself and understand. The more I used each time, the more
comfortable I became with the software.
The second problem that I faced was related to the task instruction. It is difficult to pull the
necessary dimensions out of it especially the curve angle. To overcome this problem, I recall
all of the knowledge I gained from CAD 3 class to apply in this task.
IV. CONCLUSION AND RECOMMENDATION

The goals of this practical task were to further develop engineering manufacturing skills by
introducing new tools and software, as well as testing the old ones in more advanced and
efficient ways. It was also to improve technical writing and IT site creation ability. I believe
that I have accomplished all of these goals very well.
These are the recommendations that can be used to improve the efficiency of the task:
I. Make sure that students can practice the CAD/CAM by having an appropriate software.
II. Conduct further lectures to guide students on how to use the CAD/CAM software.
III. Ensure that students are briefed about the task that will be conducted earlier.
IV. Use all of the ribbon and constrain provided by the software.
