Metal Processing


The curricular unit’s main objective is to confer to the student a solid knowledge about the metallic materials shaping technologies and processes, as well as their positioning in the general scheme of processing technologies.
Taking into account the structure-properties relationships governing material’s behaviour, the student should be able to identify the relative advantages and limitations of the processes, to understand the functioning of the machinery used to implement those processes, and to understand the influence of the various process parameters. Thus, he/she should be in a position to adequately select the best technologies to be used to produce a given part, planning the sequence of processing steps of the material as a function of its properties as well as of the intended application; also, the student should be able, when presented with a defective processing result, to evaluate the possible causes for error and to correct them.

Teaching method

Two types of lessons will be considered: Lectures and laboratory. Lectures will be given using PowerPoint slides, students having access to copies on the course page in the Moodle platform. The laboratory work will be performed by the students under the guidance of the teacher and focus on the different topics of the syllabus.
A series of visits to industrial plants dedicated to metallic materials processing may complement the unit.

Evaluation method

Two tests, individual and collective assigments, final exam.

Frequency is achieved through the following cumulative conditions:

  • participation in at least 50% ot the TP classes;
  • participation in at least 90% of the P classes;
  • submission of an individual report, to be assigned.
  • submission of a collective report on the laboratory assigment.

The tests are not mandatory, but should be undertaken to insure exemption from the final exam; a minimum average mark of 9.5 is required to insure exemption from the final exam. If this condition is not fulfilled, the student must submit to the final exam.

The final grade (NF) is obtained as:

NF = 0.30* T1 + 0.30 + T2 + 0.40* P (for the case of exemption from the final exam) or;

NF = 0.60*NE + 0.40* P (for the case of participation in the final exam).

In the above, T1 and T2 are the grades attained in the mid-term tests, P is the average grade from the individual and collective reports and NE stands for the grade in the final exam.
