CAD/ CAM technologies to design and manufacturing mechanism/ machines.

Manufacturing Processes – MEEN 3311
Description and requirements:
Select a suitable system (mechanism/ machine) for manufacturing as per
specifications detailed below:
Objective of the Assignment:
The objective is to use modern CAD/ CAM technologies to design and manufacturing
mechanism/ machines.
Students are required to design the model in any CAD software. Also, select suitable
material and manufacturing process.
Specifications, Constraints and Standards:
•
•
•
•
•
•
•
•
•
Design the system in any CAD software
Provide drawings (with dimensions) in the project report
System should be DC motor driven
Overall dimensions of the mechanism must be not exceeding 30 cm × 30 cm × 30 cm
Overall weight should not exceed 1 Kgs
Consider economic factors in selecting materials and different parts
Consider environmental factors in selecting materials (Recyclable materials) and
manufacturing process (Energy efficient processes)
Safety must be ensured in the use and handling of the final product
When standard parts (for example: nut bolts, screws, bearings, gears, nails, etc.) and
materials are used, mention the relevant standard.
Design Assignment consists of following two tasks:
Task # 1:
Submit a project design report on the design of the system. The report must consist of the
following sections:
•
•
•
•
•
•
Objective
Design Specifications, Constraints and Standards
Design Methodology: Computer Aided Design of the system, Drawings with dimensions,
selection of suitable material and process to manufacture it.
Neat and clear sketches and dimensions of all parts of model.
Include various pictures of your manufactured product.
References must be properly written at the end of the report.
Manufacturing Processes – MEEN 3311
Task # 2:
•
•
You are required to manufacture a miniature model as per design calculations and
constraints
System/Design Verification: All parts should be assembled and tested. Model should
be DC motor driven.
