Academic management

The subject of Machine Technology is a compulsory subject that is taught in the 1st semester of the 4th year of the degree in Industrial Technology Engineering, belonging to the subject "Mechanics and Materials" of the module "Specific Technology".

In this subject the theoretical and practical contents that allow to understand the fundamentals of the design of machines and their main constituent elements are exposed. In this way students will acquire skills related to mechanical engineering, as understanding and calculating different components of mechanical systems.

It is highly recommended that students have passed previous subjects such as Expansion of Mechanics, Material Resistance, Theory of Machines and Mechanisms, Materials for Industrial Technologies and Graphic Expression II, to facilitate the monitoring and practice of the subject.

In addition, it will be necessary to use computer programs at the user level, so the student must be familiar with different commonly used software, which will allow the use of the specific software of the subject.

The general/transversal competencies indicated in the verification report for this subject will be worked on:

The contents of this subject correspond to the following topics:

BLOCK I: Fundamentals

Topic 1. Fundamentals of Mechanical Design

Topic 2: Stress Analysis and Static Failure Theories

Topic 3: Calculation to fatigue of machines. Fatigue Failure Theories

BLOCK II: Power transmission elements. Drives

Topic 4: Rigid Transmissions. Gears and Drive Trains

Topic 5: Flexible Transmissions

BLOCK III: Elements of Machines

Topic 6: Shafts, keys, couplings, bearings and supports

When circumstances require, online teaching could be used for all the activities of the subject: expository classes, classroom practices, laboratory practices and tutorials.

Expository Classes

The professor will expose and explain the theoretical contents of the subject, with special emphasis on the most novel aspects or of special complexity, integrating both the theoretical aspects and the examples that facilitate the reasoning and analysis of the exposed matter. Therefore, regular attendance at these exhibition classes is highly recommended. It is also necessary that the student complete the study of the subject with the reading of the recommended bibliography, to contrast and expand the knowledge transmitted in the class.

Classroom practices

They will consist in the resolution of problems. As far as possible, we will try to provide the students with these problems beforehand, so that they can analyze them and thus be able to raise doubts at the beginning of the class, which will be solved jointly by the teacher and the students themselves.

Laboratory practices

The laboratory practices will be carried out in sessions of 2 hours, with a total of 7 sessions. Of voluntary attendance, its contents besides to be evaluated in the section "practices" can comprise of the final examination.

Practice 1: Fundamentals of Machine Technology.

Practices 2, 3, 4: Transmissions.

Practices 5, 6, 7: Machine Elements.

Group tutorials

The sessions will be developed in small groups of students in which they will clarify their doubts with the teacher, and also encourage critical analysis and reasoning. To do this, students will be offered formative activities that must be solved outside the classroom and presented in these seminars or group tutorials.

The academic tutorials with the teachers will be requested by the students through email. The teachers will indicate the order and the hours in which said tutorials can be made to avoid that several students attend at the same time and have to wait in line.

To access the laboratories or computer rooms in the area of Mechanical Engineering, students must first ask the teachers of the subject on the access regime to these laboratories as well as on the use of materials and equipment. Students will need explicit authorization from teachers to access these laboratories or rooms.Con objeto de facilitar y racionalizar la organización docente de la Universidad, se propone la siguiente tipología de modalidades organizativas:

When circumstances require, online assessment could be used, not only for final exams but also for classroom and laboratory practices.

ORDINARY CALL:

The subject will be evaluated based on the following criteria with the indicated weights:

• Theoretical or practical exams: 75%

• Report and development of the Laboratory Practices and activities developed in Group Tutorials: 25%

The lack of grammar and spelling will negatively influence the grade of all documents submitted by students, as well as a sloppy presentation.

The exams will include questions of conceptual type or problems of rapid resolution, to evaluate the acquisition of the fundamental concepts of the subject, as well as their reasoning ability, and problems, of complexity level similar to those made during the semester, to verify the ability of the student in the practical application of theoretical knowledge and mastery of techniques in problem solving. The score of each problem will be specified in the statement. The exams will consist of 2 parts: a first theoretical part that will not allow the use of support material and a second part of solving practical exercises in which notes and tables of the subject can be used, being totally excluded the exercises solved.

The exercises, works and exhibitions will be individual and / or in groups. The technical content, the correct structuring of the knowledge and the use of the adequate terminology will be valued.

The laboratory practices will be carried out individually or in groups depending on the practice and the teacher's instructions. Aspects such as the previous preparation of the practice, the attitude in the performance of the same, the delivery of a record that includes the work done individually in each laboratory session within the indicated periods or the completion of questionnaires in Virtual Campus will be evaluated.

To pass the subject, a total grade equal to or greater than 5 out of 10 (50%) must be obtained, but a minimum grade of 40% must be obtained in the final theoretical and practical examination. If that minimum grade is not reached in the exam, the subject will not be passed even if the total sum of grades is equal to or greater than 5. In this case the qualification that will appear will be: 4.9 Suspense

EXTRAORDINARY CALL:

The evaluation in extraordinary call will be made through a practical theoretical examination in which the contents of Expositive Classes, Classroom Practices and Laboratory Practices will be evaluated. This test constitutes 100% of the grade and the pass is 50%.

DIFFERENTIATED EVALUATION:

The evaluation in differentiated call will be made through a practical theoretical examination in which the contents of Expositive Classes, Classroom Practices and Laboratory Practices will be evaluated. This test constitutes 100% of the grade and the pass is 50%.

The student will have at their disposal in the Virtual Campus:

Notes of the subject.

Scripts of laboratory practices.

Statements of the problems to solve in the classroom practices.

Proposed and solved exercises.
