摘要: In this work, the design and implementation of a set of practical activities in a flexible manufacturing cell is exposed, as well as the teaching methodology used, both in programming cell manually (guided programming) or remotely (off-line, using simulation software). These activities have been designed for a progressive learning, starting with simple tasks, like programming a robot arm movement between different points in space, and concluding with more complex tasks, such as programming of palletizing cycles or manufacturing a part by machining.

摘要: This work develops a methodology that allowed students to associate the effect of some cutting variables with chip type. For that, turning processes were carried out on two different materials since their physical and mechanical properties have a relevant influence on the chip formation. Cutting tests were run by varying the feed rate, while cutting speed and depth of cut had fixed values. These cutting conditions led to different chip geometries being obtained. Thus, it was possible to establish a chip type classification in turning operations. The methodology herein presented is based on new technologies, which raised great expectations among students, who positively considered this experience. The effect of other variables, apart from feed rate, must be theoretically analyzed in order to improve the comprenhension of the process herein involved.

摘要: Materials technology is a matter of great applicative and crosscutting interest, as evidenced by their presence in most curriculums of the current industrial engineering degrees. During the development of this matter, it is crucial that the student assimilates not only the relationship among composition, processing and mechanical properties, but also, how all these technological features interact facing the in-service behavior of the material. That is why, within a Doctoral dissertation developed at the Department of Construction and Manufacturing Engineering at the National Distance Education University (UNED), it has designed a computer tool to quantify the stringency level of technological requirements of materials (especially suitable for high demanding applications), characterized by its suitability as interactive teaching material used in the teaching of materials engineering. As a case study, we have chosen a selection of materials for nuclear reactor pressure vessels, because it is a very representative example of the relationship between chemical composition, mechanical properties and in-service behavior.

摘要: This paper presents different examples of automatic generation of queries to be implemented in a b-learning platform. Queries can be used as complementary contents and self-assessment by students in Manufacturing Processes subjects. They are useful when the available time for classroom teaching is reduced and also in blended applications, allowing students the consolidation of in-person received knowledge. Firstly, some considerations about the teaching of Manufacturing Processes subjects and about the types of queries to be generated automatically are explored. Secondly, a list of potential manufacturing topics for which this methodology is suitable is proposed, selecting three of them. Finally, and by means of non-specialized computer tools, an example of application is developed and the obtained results are presented in each topic.

摘要: The present work develops a learning methododology based on experiments related to the cutting temperature concept in turning processes. This proposal allows students to measure the temperature actually reached during a typical turning operation with a semi-automatic lathe. Temperature data are collected by a thermographic camera, which implies acquiring competences in this technique. The different tests involved in the practical experiment are defined for various cutting speeds and feed rates, and for a constant depth of cut. Two different materials are considered to point out the influence of turning parameters on cutting temperature.

摘要: The aim of this work is to analyze the teaching and learning process applied to degrees that enable regulated professional activities with competences related with Manufacturing Engineering; and raise the training paths followed in relation to FERSA-University of Zaragoza Chair to improve the acquisition of practical skills related to manufacturing engineering. The weaknesses that currently exist in the curricula and the developed mechanisms to better adapt to the acquisition of skills and learning outcomes will be analyzed.

摘要: The aim of this paper is to analyze the use of Finite Element Analysis (FEA) in the teaching-learning strategy of metal forming processes. To this end, students are proposed to use the commercial package DEFORM-3D® for the development of their bachelor and master theses within the research line on incremental sheet forming processes. The student acquires skills and competencies on numerical simulation and design of real metal forming processes valuable for their future professional practice, while strengthening the foundations of these manufacturing technologies. This proposal is consistent with the active teaching methodologies included in the guidelines of the European Higher Education Area (EHEA).

摘要: The present times are changing and need new formulas that satisfy the need for effective transfer between universities and companies. In the Basque Country, attending to this demand the Aeronautics Advanced Manufacturing Center (CFAA) has been founded. This center belongs to the University of the Basque Country (UPV/EHU) and has several companies related to this strategic sector as partners. The CFAA, equipped with the latest machinery and technology, born to be a catalyst for research activity in the field of advanced manufacturing for aeronautical sector, focusing its activity on the called Pillar 2 of the MRL scale (Manufacturing Readiness Level) as the proximity to the final application. Belonging to the UPV/EHU, this center allows stays of doctoral students, students for performing their master and bachelor’s degree projects. This implies a high quality training, and closer to reality, in manufacturing technologies.
