Argomento e obiettivi del testo
 It Works! è un corso di inglese tecnico per gli studenti dei corsi con indirizzo Elettronica, Elettrotecnica e Meccanica, con focus sulla Manutenzione e Assistenza Tecnica.
 
 I contenuti, veicolati attraverso testi di livelli di diversa complessità, vengono esplorati utilizzando le quattro abilità in modo omogeneo ed integrato. Il testo dà inoltre grande importanza alla pratica linguistica attraverso attività che agevolano la revisione e la ripetizione dei contenuti studiati, favorendone l'apprendimento e l'interiorizzazione.
 I brani offrono un assortimento di stili, registri e livelli di difficoltà, e sono tratti da fonti diverse ed autentiche: libri e manuali, riviste e quotidiani online e siti web, anche specialistici.
 
 Il testo si propone di:
 
 <ul><li>far acquisire le competenze necessarie per comprendere testi che presentano termini, espressioni, strutture sintattiche e modalità discorsive specifiche del linguaggio settoriale;
</li><li>migliorare le capacità di ricezione e produzione orale e scritta;
</li><li>consolidare abitudini grammaticali corrette;
</li><li>incoraggiare l'autonomia linguistica e la soluzione di problemi;
</li><li>stimolare l'interesse e la partecipazione attiva degli studenti, dando spazio alla loro esperienza personale e a problematiche di attualità.
</li></ul>La struttura
 It Works! è diviso in cinque Moduli, ognuno dei quali ripartito in un numero variabile di Unità.
 Ogni Unità è suddivisa in brevi Capitoli su due pagine – teoria ed esercizi – per favorire sia uno studio più parcellizzato, sia la scelta antologica da parte dell'insegnante.
 
 Brevi link (curiosità, ampliamenti, rimandi, attività o mini-approfondimenti) arricchiscono i brani per consentire una maggiore interattività. Il primo esercizio di ogni capitolo è sempre una mappa riepilogativa da completare che aiuta a focalizzarsi sulle key words e i contenuti chiavi del testo proposto.
 Un ricco apparato iconografico, infine, accompagna i brani di lettura, per ognuno dei quali è previsto un esauriente glossario.
 
 Ogni Unità si conclude con tre sezioni:
 
 <ul><li>Vocabulary and Praseology: attività di revisione e consolidamento del lessico;
</li><li>Case study: argomento di attualità corredato di esercizi mirati all'approfondimento e alla discussione;
</li><li>Mapping your Mind: mappa riepilogativa per rappresentare la rete di relazioni tra i vari argomenti delle unità e a fissare le key words.
</li></ul>Alla fine di ogni Modulo, il testo propone ulteriori attività:
 
 <ul><li>Real-Life skills: compiti di realtà reali e collaborativi, con un taglio di tipo pratico calato nella realtà;
</li><li>Clip: brevi filmati tratti da opere cinematografiche.
</li></ul>Contenuti digitali integrativi
 
 <ul><li>Video per attività di listening e speaking
</li><li>Tracce audio in formato mp3
</li><li>Schemi e mappe interattive
</li><li>Testi per attività di approfondimento e di esercitazione
</li><li>Schede di civiltà comparata UK vs US
</li></ul>Teacher's Book. Disponibile sia in formato cartaceo sia digitale.
 
 <ul><li>Programmazione didattica / Piano di lavoro

SECTION 4 – MECHANICS

93 G-code is the name of the most widely used CNC programming language. It is used mainly in computeraided manufacturing (CAM) to control automated machine tools. What are composites? Many CNC machine tools come equipped with a tool changer that automatically switches between tools during machining, enhancing efficiency and reducing downtime, i.e. the period when the machine is not working. CNC milling machine enclosure: chiusura fabric: tessuto 218 MECHANICS CNC MACHINE TOOLS Computer Numerical Control (CNC) machine tools are advanced manufacturing machines that operate using computerised controls to automate machining processes with high precision and repeatability. Rather than manual operations, CNC machines follow pre-programmed instructions which are delivered to them in the form of sequential program instructions (such as G-code ) and then executed. The program can be written by a person or, more often, generated by CAD software.   Key features of CNC machines   High-speed machining: CNC machine tools can operate at high rotational speeds for cutting tools, allowing for fast material removal, especially when using advanced materials like titanium or composite materials .   Software integration and simulation: CNC machine tools are often integrated with CAD/CAM software, which enables the creation and simulation of machining operations before actual production.   Enhanced safety features: CNC machine tools are equipped with safety mechanisms such as emergency stop buttons, protective enclosures, and sensors to prevent accidents. Additionally, because the operation is automated, there is less direct interaction between the operator and the machine during operation.   Types of CNC machine tools CNC machine tools are used in various industries for cutting, shaping, and finishing materials such as metal, plastic, wood, and composites. Below are the main types of CNC machine tools.   A CNC milling machine can have 3 to 6 axes, allowing movements in different directions to create complex shapes, contours, and detailed parts. It can have a wide range of cutting tools, each having a different purpose. It is highly precise with micron-level accuracy. CNC plasma cutting machine   A CNC plasma cutting machine delivers highly accurate cuts using an electrical discharge arc (such as a plasma torch) to ionise the air and melt the material where the torch strikes. Since they work on an electric discharge mechanism, plasma cutters can only be used for machining electrically conductive materials.   A CNC laser cutting machine can cut through many materials, such as plastic, paper, fabric, metals, and hardwood. It uses a powerful beam of highly focused light (a laser) to perform this task and has a smaller point of contact, leading to a higher accuracy level and better surface finish. CNC laser cutting machine   A CNC lathe produces a finished product much faster and with more precision than manual lathes. It is ideal for various processes, like cutting, sanding, facing, drilling, turning, knurling, etc.
