Transcription

1 Unit Title: OCR unit number 9 Level: 2 Credit value: 5 Guided learning hurs: 40 Unit reference number K/503/5862 An intrductin t Rapid Manufacturing Unit purpse and aim This unit will intrduce learners t the field f Rapid Manufacturing. Learners will develp their knwledge f the technlgy, hw it wrks and the different types f machines and technlgies used. Learners will cnsider the advantages and limitatins f Rapid Prttyping (RP) and Additive Manufacturing (AM) alng with the key develpments that have shaped the technlgy. Learners will use the technlgy, t analyse an STL file and prduce a cmpnent using a rapid prttyping r additive manufacturing machine. Learning Outcmes Assessment Criteria Teaching Cntent The Learner will: The Learner can: 1 Understand Rapid 1.1 Identify the key features f Key features: Rapid Prttyping and layering technlgy Manufacturing Additive Manufacturing prcesses prduced directly frm 3D CAD data 1.2 Describe the different types f Rapid Prttyping and Additive 1.3 Identify the technlgical develpments f Rapid Manufacturing utilise STL frmat range f materials uncnstrained gemetry creatin Different types f systems include: FDM SLA SLS LOM Key develpments: develpments in speed advances in materials OCR

4 Learning Outcmes Assessment Criteria Teaching Cntent Learners will be able t assess the finishing requirements f a cmpleted cmpnent supprt remval sluble supprt remval cmpnent finishing sanding, painting final applicatin assessment chemical catings r impregnatin Assessment This unit is centre assessed and externally verified. In rder t achieve the unit yu must prduce a prtfli f evidence which, n request, will need t be made available t the OCR external verifier. Prtflis f wrk must be prduced independently and centres must cnfirm t OCR that the evidence is authentic. Evidence requirements Learners will prduce a written reprt/pster/display bard/verbal presentatin discussing the different types f rapid prttyping and additive manufacturing systems. It shuld cver the key features f such systems and the technlgical advancements that have taken place since its inceptin. It will discuss advantages, applicatins and the future develpments f rapid prttyping and additive manufacturing systems. The presentatin will be supprted by practical evidence f a rapid prttyped part prduced n a machine by the learner. Guidance n assessment and evidence requirements Tutrs shuld ensure that the delivery f this unit is as practical as pssible. Learners shuld be given expsure t rapid prttyping equipment and allwed time t use the machine. If centres d nt have access t a machine then partnerships with lcal cmpanies, universities r clleges culd be frmed. Tutrs shuld ensure that learners are taught abut the range f different technlgies available regardless f the in-huse system. Learners shuld als understand and be able t assess a variety f mdels t decide the apprpriate rientatin and effectiveness f the build. 4 OCR 2011
