  Description
Laboratory practicals The practical sessions for this course are comprehensive and include: - Measurement techniques used in manufacturing for quality control. - Description of machine tools, tools, and fixtures used in manufacturing processes, as well as their working conditions. - Specific software for integrating manufacturing stages and Numerical Control. Due to the complexity of understanding the subject matter without directly experiencing manufacturing practice, attendance at the practical sessions is considered essential. Although attendance is not compulsory, each practical session is assigned a score that can only be achieved by participating in person.
Other methodologies In addition to laboratory practices, the professor will propose other in-person activities during the course, such as specific exercises, case studies, and/or debates, with the intention of encouraging and arousing the students' interest in the subject matter. These activities will be conducted in person and in groups.
Lecture The lectures will have a theoretical content with a clear technological orientation specific to the subject matter. Additionally, problems will be solved to reinforce the concepts. The presentation will preferably encourage participative development, stimulating student attendance.

Description
Students are welcome to approach the professor for individual tutorials to address any questions or concerns that may arise regarding the methodologies and activities proposed during the course

Assessment
  Description Qualification
Laboratory practicals All practical sessions will include one or several related activities, which will serve as the basis for their assessment. These evaluations will be conducted in person, either during or at the end of each practical session. 20%
Other methodologies Throughout the supplementary activities, the professor will propose various exercises, quizzes, and/or small evaluative assignments to monitor the students' learning progress continuously. 10%
Mixed tests The mixed tests will consist of multiple-choice theoretical questions and short-answer questions. Two partial exams will be conducted during the course to assess the theoretical part of the subject. The total score will be 30 points (20 points for the first partial and 10 points for the second). It will be necessary to achieve a minimum of 40% on each partial exam in order to add the rest of the grades obtained during the course. 30%
Extended-answer tests Two partial exams will be held during the course to evaluate the problem-solving part of the subject. The total score will be 40 points (25 points for the first partial and 15 points for the second). It will be necessary to achieve a minimum of 40% on each partial exam in order to add the rest of the grades obtained during the course. 40%
 
Other comments and second call

In the second examination period, only the mixed tests and/or undeveloped tests not passed during continuous assessment can be retaken.

The criteria applied will be the same as those applied in the first examination period.
