Objectives

JUSTIFICATION:

CAD, CAM and CAE are essential tools for the development and manufacture of products. Manufacturing industries using plastic or aluminium injection, as well as foundries, depend directly on CAD/CAM/CAE. Students have to be familiar with these technologies.

OBJECTIVES:

Learning the processes of product development:
- CAD, CAM and CAE;
- CNC milling equipment;
- CMM measuring and 3D scanning;
- Rapid prototyping.
Simultaneously it is intended that students know the major brands and products in these areas and know their advantages and limitations.

RESULTS OF LEARNING AND SKILLS:

- Research and structuring of technical information;
- Basic knowledge in the use of applications like: AutoCAD, SolidWorks, PowerShape, PowerMILL, CopyCAD, SOLIDCast and CosmosWorks;
- Being able to discuss the implementation of CAD/CAM/CAE technology in a company;
- Troubleshoot common problems within CAD/CAM/CAE, metrology, reverse engineering and rapid prototyping.

Program

In each lesson a technology is presented at the beginning of the class. Next students will perform a practical application of this matter, using the respective tool or application.

To accomplish this discipline, a protocol was established with Cinfu (Training Centre of Foundry Industry), which provides the equipment covered and where this course is taught.

The different topics are organized according to the typical sequence of the product development. At the beginning of the semester a part is defined, which will demonstrate the different stages of product development. Students should follow this development through a report that represents the different stages of product development.

The topics discussed during the semester are:

2D and 3D CAD
- Introduction to CAD
- Entities used in 2D CAD
- Operations on entities
- From 2D to 3D
- Surfaces vs. Solids
- Analysis of major CAD programs
- Transfer of CAD files
Machining (CAM), Computer Aided Manufacturing
- Presentation of technology
- Generation of machining tool paths
- Preparation of a machining centre and running the NC program generated with the CAM software
Computer-aided engineering (CAE)
- Mathematical Principles
- Simulation of mechanical properties
- Simulation by finite differences
- Reverse Engineering ("Reverse Engineering")
Three-dimensional scanning
- Scanning Process
- Processing of point clouds
- Generation of triangulated meshes
- Generation of surfaces
Metrology
- Introduction to metrology
- CMM Machines
- Measurement geometric
- Inspection dimensional

Rapid Prototyping
- Presentation of rapid prototyping
- Discussion of different technologies
- Preparation and production of the part using the SLS machine at Cinfu

Teaching methods and learning activities

During the lectures, it is common practice to ask students for active participation and intervention in order to issue opinion on some of the topics covered or to be clarified all the doubts that arise.

Generally, the first few minutes of each class serve to summarize the matters discussed in previous classes, attempting to give continuity to subjects taught in class. It is also common to make a summary at the end of each lesson.

The classes are divided into the following parts:

- A theoretical component where each technology is addressed in the development and manufacture of products
- A theoretical and practical component where students follow tutorials to quickly get to basics in the use of different tools
- A practical component in which students use the tool for the development of the product selected at the beginning of the semester: the different stages of the product development of this part will have to be documented by the students and constitute the final paper

Whenever possible, the concepts are presented through practical examples of industrial activity to enable a better understanding. It is intended that this course is taught with a view to direct application in industry, as regards to the use of technologies and implementation of CAD/CAM/CAE and Rapid Prototyping.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Description	Type	Time (hours)	Weight (%)	End date
Attendance (estimated)	Participação presencial	48,00
Creation of product development report	Defesa pública de dissertação, de relatório de projeto ou estágio, ou de tese	70,00		2012-06-22
Evaluation and exams	Exame	44,00		2012-06-22
	Total:	-	0,00

Eligibility for exams

It is necessary to achive 50% evaluation in both “practical classification" and “theorical classification".

Calculation formula of final grade

The final classification is calculated with this formula:

Final classification = "ractical classification" * 0.30 + “theorical classification" * 0.70

Examinations or Special Assignments

During the semester, the students will have to do different tasks and may have to do small tests.

Special assessment (TE, DA, ...)
