Laser processing</p><p>This unit will cover applications of advanced lasers in high-precision manufacturing processes. Short and ultrashort-pulse laser systems will be characterized in terms of the beam parameters that are relevant for typical micro-precision manufacturing applications. Example laser micro-precision processing, micro-drilling, thin films and surface texturing will be detailed. Mask-based processing and direct writing techniques will be described. The unit includes a laser processing Laboratory exercise with practical examples of micro-drilling and cutting.</p><p>2. Electrical machining. ¿</p><p>Two main processes will be covered, Electrochemical machining and Electro-discharge Machining.</p><p>With regards to the ECM process the syllabus covers typical machine layouts and systems. Process parameters and typical products. Process principles. Electrochemical equivalent. Electrolyte types. Machining electro-dynamics. Process problems. Workpiece surface characteristics. Electrochemical grinding. ¿Modelling of ECM&nbsp; as well as industrial applications of the process. With regards to Electro-discharge machining the syllabus covers a&nbsp; process science. Discharge generator circuits. Comparison of a relaxation generator with Transistorised type. Analysis of Relaxation circuit EDM and analysis of pulses in transistorised type. Process variables and their effect on the process, tool and workpiece. &nbsp;Micro-EDM drilling applications in industry. Associated processes of electroforming and water-jet cutting will be presented. A laboratory exercise on Electrical machining will also form part of the Unit.</p><p>3.
