Computer Numerical Control Programming

Objectives

This Computer Numerical Control Programming course introduces students to the manufacturing methods used in CNC, plastic injection, welding of ferrous materials and additive manufacturing processes present now, or in the near future, in an industrialised environment. Special emphasis will be made on the machinery, programming and selection of tools necessary to carry out these processes.

Learning outcomes

• RA1. Knows systems and processes of conformation, machining, union and quality control of manufacturing processes.
• RA2. Analyses, applies and resolves conformation systems and processes.
• RA3. Knows and applies modelling technology, rapid manufacturing techniques, characterisation of materials and applications.
• RA4. Coordinates and works as a team, rigorously using terminology and notations, to prepare the project documentation.
• RA5. Critically analyses the results obtained and exposes orally the works entrusted.

Competencies

Specific skills

• Know about and apply the principles of production systems and manufacturing processes, metrology and quality control and environmental and sustainability technology in engineering and the automotive sector.
• Understand the principles of mathematical theory in order to solve mathematical problems that may arise in engineering and apply knowledge to: linear algebra, geometry, differential geometry, differential and integral calculus, ordinary and partial differential equations, numerical methods, numerical algorithms, statistics and optimisation.
• Work in a multilingual, multidisciplinary environment, and make oral presentations and write reports in English in the field of engineering, in general, and in the automotive sector, in particular.

Basic skills

• Students have the ability to gather and interpret relevant data (usually within their field of study) in order to make judgements that include reflection on relevant social, scientific and ethical issues.

Core skills

• Exercise active citizenship and individual responsibility with a commitment to the values of democracy, sustainability and universal design, through practice based on learning, service and social inclusion.

Content

Evaluation

Students will be evaluated with different deliveries of reports and/or oral presentations of the following topics:

• Deliveries of the Mechanized machine block: 40% (20% project + 20% practical)
• Deliveries of the Injection block: 30% (15% project + 15% practical)
• Deliveries of the Welding block: 15% (7.5% project + 7.5% practical)
• Deliveries of the Additive manufacturing block: 15% (7.5% project + 7.5% practical)

It is planned to make an oral presentation, in addition to the delivery of a report, by groups of a work done along the course and contains all the competences mentioned above. This project will count 50% of the final grade, while the other 50% belongs to the practices of each block. The recoverable part will be the part related to the work, which will be given some indications at the end of the course and the student will have to carry out the task in a certain period of time. Practices are not recoverable.

Methodology

This course presents the following methodologies:

• Online theoretical classes
• Online practical classes, using simulation programs
• Students are expected to consult autonomously the sources of recommended bibliography and other sources of information for the realisation of the project
• Specific tutorials in case of doubts, via email or virtual conference
