3 1. INTRODUCTION 1.1 NAME AND DESCRIPTION OF THE SKILL COMPETITION THE NAME OF THE SKILLS COMPETITION IS CNC Milling DESCRIPTION OF THE ASSOCIATED WORK ROLE(S) OR OCCUPATION(S) Cmputer Numerical Cntrl (CNC) technlgy has reached the stage f having becme mnipresent. Mst peple cannt imagine hw imprtant these technlgies are in their lives. There is nthing that we use that hasn t in its manufacturing utilized CNC technlgy. It is present in prducts and bjects f everyday life as e.g. cars, airplanes, cmpnents f machines f all types, mulds fr tls used fr husehld machines, medical prsthetics, cell phnes and tys etc. CNC milling machines are machine tls which are used fr the shaping f metal and ther slid materials. These machines exist in tw basic frms: hrizntal and vertical. This refers t the rientatin f the cutting tl spindle. Early milling machines were manually r mechanically autmated, but technlgical advances have led t the develpment f Cmputer Numerical Cntrl, such as CNC machining centre. CNC refers t a cmputer ( cntrl ) that reads and stres instructins. This numerical infrmatin generally G & M cdes (a prgraming language) is then used t cntrl and drives a machine tl, a pwered mechanical device ( machining centre ). A machining centre is used t fabricate cmpnents using cutting tls fr remval f material. CNC technlgy includes machining tls such as lathes, multi-axis spindles, wire electrical discharge machines and milling machines, where the functins frmerly perfrmed by human peratrs are nw perfrmed by a cmputer cntrl mdule. The prfessinals assciated with this skill use CNC machines (3-Axis, 4-5 Axis r Multi-Axis machines) t cut and shape precisin prducts as mentined abve. T frm the finished part, the cutting prcess can be started frm a slid blck, pre-machined part, casting r frgings. Fr thse scenaris, the skill requires the CNC milling machinist t read and interpret cmplex technical drawings and specificatins and wrk t a high degree f precisin and detail; t be prficient at metal wrk skills and understand hw metals react t varius prcesses; t be a skilled cmputer peratr in rder t use industry specific sftware; t be highly skilled machine peratr. A prgram is required t perate the machine tl, can be generated manually r using Cmputer Aided Design/Cmputer Aided Manufacture (CAD/CAM) sftware. T achieve the finished part the CNC milling machinist prfessinals undertake a sequence f essential activities: Interpret engineering drawings and fllw the specificatins Generate a prcess and prgram (lgical prcess plan) with a CAD/CAM system and/r G & M-cdes Set up the tling, wrk hlding device and wrk piece n the CNC milling centre Manipulate cutting cnditins, based n the prperties f the material and tling used Operate, inspect and maintain the accuracy f dimensins within the specified tlerances Optimise the prcess taking int accunt the prductin type: large quantities f ne part, small batches r ne-f-a-kind items. Tday a wide range f industries require CNC milling machinists prfessinals t prgram, perate and keep sphisticated machining centre s running in an efficient and reliable way.

5 2. THE STANDARDS SPECIFICATION 2.1 GENERAL NOTES REGARDING WSSS / WSESS Where apprpriate WSE has utilised sme r all f the WrldSkills Internatinal Standards Specificatins (WSSS) fr thse skills cmpetitins that naturally align between the tw internatinal Cmpetitins. Where the skill is exclusive t the EurSkills Cmpetitin, WrldSkills Eurpe has develped its wn Standards Specificatin (WSESS) using the same principles and framewrk t that used fr the develpment f the WSSS. Fr the purpses f this dcument the use f the wrds Standards Specificatin will refer t bth WSSS and WSESS. The Standards Specificatin specifies the knwledge, understanding and specific skills that underpin internatinal best practice in technical and vcatinal perfrmance. It shuld reflect a shared glbal understanding f what the assciated wrk rle(s) r ccupatin(s) represent fr industry and business. ( (TBA fr WrldSkills Eurpe) Helpfully, fr the glbal cnsultatin n the WSSS in 2014, arund 50 per cent f respnses came frm Eurpean industry and business. Each skill cmpetitin is intended t reflect internatinal best practice as described by the Standards Specificatin, and t the extent that it is able t. The Standards Specificatin is therefre a guide t the required training and preparatin fr the skill cmpetitin. In the skill cmpetitin the assessment f knwledge and understanding will take place thrugh the assessment f perfrmance. There will nt be separate tests f knwledge and understanding. The Standards Specificatin is divided int distinct sectins with headings and reference numbers added. Each sectin is assigned a percentage f the ttal marks t indicate its relative imprtance within the Standards Specificatin. The sum f all the percentage marks is 100. The Marking Scheme and Test Prject will assess nly thse skills that are set ut in the Standards Specificatin. They will reflect the Standards Specificatin as cmprehensively as pssible within the cnstraints f the skill cmpetitin. The Marking Scheme and Test Prject will fllw the allcatin f marks within the Standards Specificatin t the extent practically pssible. A variatin f five percent is allwed, prvided that this des nt distrt the weightings assigned by the Standards Specificatin. 2.2 STANDARDS SPECIFICATION SECTION RELATIVE IMPORTANCE % 1 Wrk rganizatin and self-management 10 The individual needs t knw and understand: the extent and impact f CNC milling n mdern life and industry quality standards fr materials and quality f metals standards fr the envirnment, safety, hygiene and preventin f accidents at wrk cmputer perating systems mathematics, especially accurate and detailed calculatins and ES2016_TD_CNC_MILLING_7_V1.2 5

10 3. THE ASSESSMENT APPROACH & PRINCIPLES 3.1 GENERAL GUIDANCE Nte: this Sectin and Sectin 4 summarize a great deal f new infrmatin and guidance regarding assessment. Please refer t the Cmpetitin Rules fr greater detail. The Cmpetitin Develpment Cmmittee (CDC) establishes the principles and techniques t which assessment at the EurSkills Cmpetitin must cnfrm. Expert assessment practice lies at the heart f the EurSkills Cmpetitin. Fr this reasn it is the subject f cntinuing prfessinal develpment and scrutiny. The grwth f expertise in assessment will infrm the future use and directin f the main assessment instruments used by the EurSkills Cmpetitin: the Marking Scheme, Test Prject, and Cmpetitin Infrmatin System (CIS). Assessment at the EurSkills Cmpetitin falls int tw brad types: measurement and judgement. Where the earlier terms bjective and subjective still ccur, these must be understd t mean measurement and judgement fr all prcedural and practical purpses. All assessment will be gverned by explicit benchmarks, referenced t best practice in industry and business. The Marking Scheme must include these benchmarks and fllw the weightings within the Standards Specificatin. The Test Prject is the assessment vehicle fr the skill cmpetitin, and als fllws the Standards Specificatin. The CIS enables the timely and accurate recrding f marks, and has expanding supprtive capacity. The Marking Scheme, in utline, will lead the prcess f Test Prject design. After this, the Marking Scheme and Test Prject will be designed and develped thrugh an iterative prcess, t ensure that bth tgether ptimize their relatinship with the Technical Descriptin and the principles fr assessment as set ut in the WSE Assessment Strategy. They will be agreed by the Experts and submitted t WSE fr apprval tgether, in rder t demnstrate their quality and cnfrmity with the Standard Specificatin. Prir t submissin fr apprval t WSE, the Marking Scheme and Test Prject will be reviewed by the WSE Skill Advisrs in rder t benefit frm the capabilities f the CIS. ES2016_TD_CNC_MILLING_7_V1.2 10

11 4. THE MARKING SCHEME 4.1 GENERAL GUIDANCE This Sectin describes the rle and place f the Marking Scheme, hw the Experts will assess Cmpetitrs wrk as demnstrated thrugh the Test Prject, and the prcedures and requirements fr marking. The Marking Scheme is the pivtal instrument f the EurSkills Cmpetitin, in that it ties assessment t the standards that represent the skills t be tested. It is designed t allcate marks fr each assessed aspect f perfrmance in accrdance with the weightings in the Standards Specificatin. By reflecting the weightings in the Standards Specificatin, the Marking Scheme establishes the parameters fr the design f the Test Prject. Depending n the nature f the skill and its assessment needs, it may initially be apprpriate t develp the Marking Scheme in mre detail as a guide fr Test Prject design. Alternatively, initial Test Prject design can be based n the utline Marking Scheme. Frm this pint nwards the Marking Scheme and Test Prject shuld be develped tgether. Sectin 2.1 abve indicates the extent t which the Marking Scheme and Test Prject may diverge frm the weightings given in the Standards Specificatin, if there is n practicable alternative. The Marking Scheme and Test Prject may be develped by ne persn, r several, r by all Experts. The detailed and final Marking Scheme and Test Prject must be apprved by the whle Expert Jury prir t submissin fr independent quality assurance. The exceptin t this prcess is fr thse skill cmpetitins which use an external designer fr the develpment f the Marking Scheme and Test Prject. In additin, Experts are encuraged t submit their Marking Schemes and Test Prjects fr cmment and prvisinal apprval well in advance f cmpletin, in rder t avid disappintment r setbacks at a late stage. They are als advised t wrk with the CIS Team at this intermediate stage, in rder t take full advantage f the pssibilities f the CIS. In all cases the cmplete and apprved Marking Scheme must be entered int the CIS at least eight weeks prir t the Cmpetitin using the CIS standard spreadsheet r ther agreed methds. 4.2 ASSESSMENT CRITERIA The main headings f the Marking Scheme are the Assessment Criteria. These headings are derived in cnjunctin with the Test Prject. In sme skill cmpetitins the Assessment Criteria may be similar t the sectin headings in the Standards Specificatin; in thers they may be ttally different. There will nrmally be between five and nine Assessment Criteria. Whether r nt the headings match, the Marking Scheme must reflect the weightings in the Standard Specificatin. Assessment Criteria are created by the persn(s) develping the Marking Scheme, wh are free t define criteria that they cnsider mst suited t the assessment and marking f the Test Prject. Each Assessment Criterin is defined by a letter (A-I). The Mark Summary Frm generated by the CIS will cmprise a list f the Assessment Criteria. The marks allcated t each criterin will be calculated by the CIS. These will be the cumulative sum f marks given t each aspect f assessment within that Assessment Criterin. ES2016_TD_CNC_MILLING_7_V1.2 11

12 TOTAL MARKS PER CRITERION STANDARD SPECIFICATION SECTIONS 4.3 SUB CRITERIA Each Assessment Criterin is divided int ne r mre Sub Criteria. Each Sub Criterin becmes the heading fr a EurSkills marking frm. Each marking frm (Sub Criterin) has a specified day n which it will be marked. Each marking frm (Sub Criterin) cntains Aspects t be assessed and marked by measurement r judgement. Sme Sub Criteria have assessment by bth measurement and judgement, in which case there is a separate marking frm fr each methd 4.4 ASPECTS Each Aspect defines, in detail, a single item t be assessed and marked tgether with the marks, r instructins fr hw the marks are t be awarded. Aspects are assessed either by measurement r judgement and appear n the apprpriate marking frm. The marking frm lists, in detail, every Aspect t be marked tgether with the mark allcated t it, the benchmarks, and a reference t the sectin f the Standards Specificatin. The sum f the marks allcated t each Aspect must fall within the range f marks specified fr that sectin f the Standards Specificatin. This will be displayed in the Mark Allcatin Table f the CIS, in the fllwing frmat, when the Marking Scheme is reviewed frm C-8 weeks. (Sectin 0).

13 4.5 ASSESSMENT AND MARKING BY JUDGEMENT In additin t measurement, Experts are expected t make prfessinal judgements. These are nrmally judgements abut quality. Benchmarks will be designed, agreed and recrded during the design and finalizatin f the Marking Scheme and Test Prject in rder t steer and supprt these judgements. Marking thrugh judgement uses the fllwing scale: 0: perfrmance belw industry standard t any extent, including a nn-attempt 1: perfrmance that meets industry standard 2: perfrmance that bth meets industry standard and surpasses that standard t sme extent 3: excellent r utstanding perfrmance relative t industry standards and expectatins. 4.6 ASSESSMENT AND MARKING BY MEASUREMENT Unless therwise stated, nly the maximum mark r zer will be awarded. Where they are used, partial marks will be clearly defined within the Aspect. 4.7 ASSESSMENT OVERVIEW Fr bth measurement and judgement there will be three Experts in the assessment team. Gd practice in assessment cmprises measurement ande judgement applied bth specifically and bradly. The final prprtins f measurement and judgment, whether specific r brad, will be determined by the standards, their weightings and the nature f the Test Prject. 4.8 COMPLETION OF SKILL ASSESSMENT SPECIFICATION The cntent f this Table is advisry and subject t change during the detailed develpment f assessment.
