Teaching methods and learning activities

The expected functioning of the Curricular Unit is as follows:

- Presentation of the topics covered in the Curricular Unit during the theoretical classes (1.5 h T) with analysis of application examples.
- In the practical laboratorial classes (2 h L), particularities will be presented, and exercises, to be developed in computer, proposed for application of the concepts presented in the theoretical classes.
- During the first classes of the Curricular Unit, several possible topics are proposed for the students’ practical works during the semester.
- The last lessons of the Curricular Unit are devoted to give more support to the practical works.

Throughout the semester, attending to the students by the Professors is possible during pre-established hours. In the days preceding the exams, the Professors offer extended attending periods to clarify doubts.

Eligibility for exams

To complete this curricular unit, the students must attain the required frequency of the practical laboratorial classes.

The students must also undergo all evaluation components, the final written exam (with 2 parts: I - CAD, II - CNC + CAD/CAM interfaces programming), the delivery of the practical assignment, and possibly its presentation and discussion.

Calculation formula of final grade

The course assessment is distributed with a final written exam and one practical work.

Each student must submit to the evaluation in all its components: one written exam without consultation allowed and made of two parts: I - 2D/3D CAD systems, II - CNC Programming + CAD/CAM/CNC/Simulation Interface Applications Development, delivery of the practical work.

The final grade results from the weighted average of the grades obtained in each of the evaluation components, with the following weights:

- Written exam: 25% + 25%; a average rating >= 30/100% is required;
- Practical work: 50%.

As to the practical work, students, individually or in groups of two, should define their theme and propose it to the teachers, who should validate them.

It is foreseen an appealing test regarding the subjects addressed in one or two parts of the final written exam.

Examinations or Special Assignments

Not applicable.

Internship work/project

Concerning the expected practical works, the students, individually or in groups of two students, should define the theme of their work and propose it to the Professors, who should validate the proposal. The process of defining the practical work ends on a date to be announced at the beginning of the semester.

The final version of the practical work should be delivered to the Professors by a deadline to be defined, two values are subtracted from the final grade for each week of delay (up to a maximum of 2 weeks delay, after which the work is not accepted).

The final dates associated with the practical works are defined with the students at the beginning of the semester and following the FEUP’s scholar calendar.

Special assessment (TE, DA, ...)

According to the General Evaluation Rules of FEUP, the students will be called to do a written examination (on all contents of the course), a practical assignment, and a possible practical CAD examination.

Classification improvement
