1 INTRODUCTION

1.1 NAME AND DESCRIPTION OF THE SKILL COMPETITION 1.1.1 The name of the skill competition is

CNC Turning

1.1.2 Description of the associated work role(s) or occupation(s).

CNC Turning is a branch of engineering. Engineers have to find mechanical solutions that can make complex designs possible. Within an assembly that you may see and use every day, every single part interacts with every other. This is true of cars, Smartphones, aircraft, and so on; the possibilities are endless. For example, there are about 10,000 parts in just one car. Engineers create assemblies of many parts, and using many different materials, through CAD (Computer Assisted Drawing) software.

Each part of an assembly is made of different materials, and needs different geometries, dimensions and surface qualities. The engineer brings all these requirements into technical drawings which are called “blueprints”. But who will build these parts? To answer that question we have to decide the best way to produce each part. There are many ways of doing this, like welding, milling, casting, and 3D Printing. One very important method is CNC Turning.

A CNC Lathe is a machine on which material turns around an axis at high speed, and where cutting tools driven by computer software are moved to cut away excessive material to get the expected part. The CNC Turning Machinist receives the blueprint. Then he/she uses the Lathe in many ways to find solutions in order to build the part. These machines are very expensive, because they can do remarkable things. To have an idea of this, think what it means to achieve accuracy below 10 microns, which is six times thinner than a human hair.

The CNC Turning Machinist has to use a computer to tell the Lathe how to move the tools and cut the part. He/she also has to set up the Lathe with all the cutting tools. These tools can cut almost every material (stainless steel, plastic, soft steel, aluminium, bronze, and so on) but we have to choose well. We also choose the clamping method. This is where the material will be held firm.

When the machine starts cutting material, the Machinist makes sure that the dimensions exactly fit the blueprint specifications. For this, very accurate inspection tools are used. A smart Machinist will get the part to fit the blueprint specifications at the first attempt.

The finished and quality controlled part is sent to the assembly line with every other part, and in the end, if everyone has done their job well, the finished assembly will meet expectations and please its customers.

2 THE WORLDSKILLS STANDARDS SPECIFICATION (WSSS)

2.1 GENERAL NOTES ON THE WSSS The WSSS specifies the knowledge, understanding and specific skills that underpin international best practice in technical and vocational performance. It should reflect a shared global understanding of what the associated work role(s) or occupation(s) represent for industry and business (www.worldskills.org/WSSS).

The skill competition is intended to reflect international best practice as described by the WSSS, and to the extent that it is able to. The Standards Specification is therefore a guide to the required training and preparation for the skill competition.

In the skill competition the assessment of knowledge and understanding will take place through the assessment of performance. There will not be separate tests of knowledge and understanding.

The Standards Specification is divided into distinct sections with headings and reference numbers added.

Each section is assigned a percentage of the total marks to indicate its relative importance within the Standards Specification. The sum of all the percentage marks is 100.

The Marking Scheme and Test Project will assess only those skills that are set out in the Standards Specification. They will reflect the Standards Specification as comprehensively as possible within the constraints of the skill competition.

The Marking Scheme and Test Project will follow the allocation of marks within the Standards Specification to the extent practically possible. A variation of five percent is allowed, provided that this does not distort the weightings assigned by the Standards Specification.

3 THE ASSESSMENT STRATEGY AND SPECIFICATION

3.1 GENERAL GUIDANCE Assessment is governed by the WorldSkills Assessment Strategy. The Strategy establishes the principles and techniques to which WorldSkills assessment must conform.

Expert assessment practice lies at the heart of the WorldSkills Competition. For this reason it is the subject of continuing professional development and scrutiny. The growth of expertise in assessment will inform the future use and direction of the main assessment instruments used by the WorldSkills Competition: the Marking Scheme, Test Project, and Competition Information System (CIS).

Assessment at the WorldSkills Competition falls into two broad types: measurement and judgment. These are referred to as objective and subjective, respectively. For both types of assessment the use of explicit benchmarks against which to assess each Aspect is essential to guarantee quality.

The Marking Scheme must follow the weightings within the Standards Specification. The Test Project is the assessment vehicle for the skill competition, and also follows the Standards Specification. The CIS enables the timely and accurate recording of marks, and has expanding supportive capacity.

The Marking Scheme, in outline, will lead the process of Test Project design. After this, the Marking Scheme and Test Project will be designed and developed through an iterative process, to ensure that both together optimize their relationship with the Standards Specification and the Assessment Strategy. They will be agreed by the Experts and submitted to WSI for approval together, in order to demonstrate their quality and conformity with the Standards Specification.

Prior to submission for approval to WSI, the Marking Scheme and Test Project will liaise with the WSI Skill Advisors in order to benefit from the capabilities of the CIS.

4 THE MARKING SCHEME

4.1 GENERAL GUIDANCE This section describes the role and place of the Marking Scheme, how the Experts will assess Competitors’ work as demonstrated through the Test Project, and the procedures and requirements for marking.

The Marking Scheme is the pivotal instrument of the WorldSkills Competition, in that it ties assessment to the standards that represent the skill. It is designed to allocate marks for each assessed aspect of performance in accordance with the weightings in the Standards Specification.

By reflecting the weightings in the Standards Specification, the Marking Scheme establishes the parameters for the design of the Test Project. Depending on the nature of the skill and its assessment needs, it may initially be appropriate to develop the Marking Scheme in more detail as a guide for Test Project design. Alternatively, initial Test Project design can be based on the outline Marking Scheme. From this point onwards the Marking Scheme and Test Project should be developed together.

Section 2.1 above indicates the extent to which the Marking Scheme and Test Project may diverge from the weightings given in the Standards Specification, if there is no practicable alternative.

The Marking Scheme and Test Project may be developed by one person, or several, or by all Experts. The detailed and final Marking Scheme and Test Project must be approved by the whole Expert Jury prior to submission for independent quality assurance. The exception to this process is for those skill competitions which use an external designer for the development of the Marking Scheme and Test Project.

In addition, Experts are encouraged to submit their Marking Schemes and Test Projects for comment and provisional approval well in advance of completion, in order to avoid disappointment or setbacks at a late stage. They are also advised to work with the CIS Team at this intermediate stage, in order to take full advantage of the possibilities of the CIS.

In all cases the complete and approved Marking Scheme must be entered into the CIS at least eight weeks prior to the Competition using the CIS standard spreadsheet or other agreed methods.

4.2 ASSESSMENT CRITERIA The main headings of the Marking Scheme are the Assessment Criteria. These headings are derived in conjunction with the Test Project. In some skill competitions the Assessment Criteria may be similar to the section headings in the Standards Specification; in others they may be totally different. There will normally be between five and nine Assessment Criteria. Whether or not the headings match, the Marking Scheme must reflect the weightings in the Standards Specification.

Assessment Criteria are created by the person(s) developing the Marking Scheme, who are free to define criteria that they consider most suited to the assessment and marking of the Test Project. Each Assessment Criterion is defined by a letter (A-I).

The Mark Summary Form generated by the CIS will comprise a list of the Assessment Criteria.

The marks allocated to each criterion will be calculated by the CIS. These will be the cumulative sum of marks given to each aspect of assessment within that Assessment Criterion.

WSC2015_TD06_EN Date: 12.08.14 – v5.0


10 of 24

4.3 SUB CRITERIA Each Assessment Criterion is divided into one or more Sub Criteria. Each Sub Criterion becomes the heading for a WorldSkills marking form.

Each marking form (Sub Criterion) has a specified day on which it will be marked.

Each marking form (Sub Criterion) contains either objective or subjective Aspects to be marked. Some Sub Criteria have both objective and subjective aspects, in which case there is a marking form for each.

4.4 ASPECTS Each Aspect defines, in detail, a single item to be assessed and marked together with the marks, or instructions for how the marks are to be awarded. Aspects are assessed either objectively or subjectively and appear on the appropriate marking form.

The marking form lists, in detail, every Aspect to be marked together with the mark allocated to it and a reference to the section of the skill as set out in the Standards Specification.

The sum of the marks allocated to each Aspect must fall within the range of marks specified for that section of the skill in the Standards Specification. This will be displayed in the Mark Allocation Table of the CIS, in the following format, when the Marking Scheme is reviewed from C-8 weeks. (Section 4.1)

4.5 SUBJECTIVE MARKING Subjective marking uses the 10 point scale below. To apply the scale with rigour and consistency, subjective marking should be conducted using:

benchmarks (criteria) to guide judgment against each Aspect

the scale to indicate:

0: non attempt;

1-4: below industry standard;

5-8: at or above industry standard;

9-10: excellence.

4.6 OBJECTIVE MARKING A minimum of three experts will be used to judge each aspect. Unless otherwise stated only the maximum mark or zero will be awarded. Where they are used, partial marks will be clearly defined within the Aspect.

4.7 THE USE OF OBJECTIVE AND SUBJECTIVE ASSESSMENT The final deployment of objective or subjective assessment will be agreed when the Marking Scheme and Test Project are finalized. The table below is advisory only for the development of the Test Project and Marking Scheme.

Total Total 10 90 100

4.8 COMPLETION OF SKILL ASSESSMENT SPECIFICATION A) Conformity to drawing – 10 marks (10% of the total score)

Total marks per module depends on the allocated duration of the module, and shall be approx. 10% of the total marks of the module.

Visual check if features and characteristic of the test part according to print, if features are missing,

or if additional features (unwanted) are on the part;

Check for corner break and chamfers and for burrs on the part;

Check for damage to part (scratches, clamp-imprints, crash-marks etc.);

Visual check of surface finishes not specified for measuring.

WSC2015_TD06_EN Date: 12.08.14 – v5.0

B) Surface finish – 10 marks (10% of the total score)


Maximum five marking aspects per module;

Measure specified locations (marked on print).

C) Main dimensions – 50 marks (50% of the total score)


Each main dimension shall carry the same weight in points.

There shall not be more than 10 marking aspects per module.

D) Secondary dimensions – 25 marks (25% of the total score)

Each dimension equals less points then a main dimension (not more than 80% of a main dimension).

E) Use of material – Five marks (5% of the total score)

Award marks only if no additional material is used by the Competitor.

Award per module = Five marks divided by number of modules.

Example: Four modules = 1.25 marks per module.

Depending on the amount of modules, a rounding of allocated marks may apply.

Example: Three modules - module one = 1.66 marks, Module two = 1.66 marks and module three = 1.68 marks.

Competitor may only receive ONE extra piece of material per test part

4.9 SKILL ASSESSMENT PROCEDURES The Experts participating in the Competition will be divided into marking groups to deal with the

assigned sections of the marking criteria;

Marking of the Test Project modules will take place on a daily basis;

ONLY the machined test part will be evaluated.

5 THE TEST PROJECT

5.1 GENERAL NOTES Sections three and four govern the development of the Test Project. These notes are supplementary.

Whether it is a single entity, or a series of stand-alone or connected modules, the Test Project will enable the assessment of the skills in each section of the WSSS.

The purpose of the Test Project is to provide full and balanced opportunities for assessment and marking across the Standards Specification, in conjunction with the Marking Scheme. The relationship between the Test Project, Marking Scheme and Standards Specification will be a key indicator of quality.

The Test Project will not cover areas outside the Standards Specification, or affect the balance of marks within the Standards Specification other than in the circumstances indicated by Section 2.

The Test Project will enable knowledge and understanding to be assessed solely through their applications within practical work.

The Test Project will not assess knowledge of WorldSkills rules and regulations.

This Technical Description will note any issues that affect the Test Project’s capacity to support the full range of assessment relative to the Standards Specification. Section 0 refers.

5.2 FORMAT/STRUCTURE OF THE TEST PROJECT The Test Project is a series of three or four standalone modules.

The modules are comprised of programming, set-up and actual machining work.

One module covers the tasks for a complete Competition day and shall not be interrupted with work from other modules (in other words, the Competitor receives one task at a time).

The floor-space and the CNC machine requirements are so intensive, that it is impossible to get a working situation where Competitors have a CNC machine totally at their disposal.

Therefore the shift rotation basis will apply, meaning Competitors have to share the CNC machine in a shift rotation (morning shift/afternoon shift). This reflects common industry situations.

Sequences example: P = CAM programming M = Machine (and CAM) is at Competitors disposal R = Reset time of machine L = Lunch

WSC2015_TD06_EN Date: 12.08.14 – v5.0


14 of 24

Considering that one hour of CAM programming can lead to approximately three hours of uninterrupted machining (set-up and turnaround included), it is desired to keep the scheduled machining time at the maximum.

It is important to have the reset-time between shift changes. During this reset-time the control-unit will be cleared, machine parameters will be reset to original stage and tools and tool holders will be taken out. The machine will be cleaned and ready for the next shift to start their Test Project.

The Sequence of a Module will be (example Morning shift):

1. 8:45 Competitors receives Drawings and Materials (including Data Transfer equipment e.g. memory

stick) and has 15 minutes for planning their work (without any other person).

2. 9:00 Buzzer will indicate the beginning of the Programming time. Competitor is only allowed to use the provided Computer for writing the CNC Program, no action at the machine is allowed.

3. 10:00 Buzzer will indicate beginning of the machining time. At this point the Competitor is allowed to use both, the Computer and the CNC Machine.

4. Buzzer will indicate the finishing of the module. The reason that during the programming time (CAM, indicated above in yellow) the Competitor is only allowed to use the Computer and not the machine, is the shift rotation system.

It may seem silly in the first shift to not be allowed to use the machine (because the machine is not occupied) but for the second shift the machine is occupied from the first shift and does not have the opportunity to use that machine. Therefore we need to create equal situations for both shifts.

5.3 TEST PROJECT DESIGN REQUIREMENTS Prior to the Competition the Chief Expert is to assign participating Experts for Test Project designing. The Chief is to assign material, sizes and desired feature and has to coordinate the modules to avoid missing competences like “face grooving, threading etc.”

Such a Test Project is one complete module. One module is the work of a full Competition day. Upon arrival to the Competition site, Experts will submit their proposals to the panel of Experts. Selection of the modules is by vote of the Experts.

A module may consist of a maximum two parts.

The modules must be designed in metric and to the standards described in the document “Project Design Criteria Skill 06”. This document will be updated and developed prior to each Competition taking into consideration the infrastructure. It will be posted on the Discussion Forum.

The Test Project design criteria were developed to:

Ensure features on modules reflect modern industry;

Minimize the amount of cutting tools for the Competitor to bring;

Minimize the amount of inspection tools for the Competitor to bring.

WSC2015_TD06_EN Date: 12.08.14 – v5.0


15 of 24

Only Test Projects meeting the following criteria will be available for selection:

Project features according to assignments by Chief Expert;

Project design to criteria of document “Project Design Criteria Skill 06“;

The Test Project drawings have to be available in ISO-E and ISO-A. Drawings shall have as little text

as possible. In the project design the focus is on “technical language” only, like dimensions and

international symbols;

Drawing available in digital format (for supply to WSI) and hard copy – source file, PDF and

printout;

Experts shall bring a machined sample part of their design. This is needed to program the CMM

(Coordinate Measuring Machine). It is also supportive in the voting for the Test Project to have a

“real” machined part available;

Proposed marking scheme has been developed.

In the situation where voting of Test Projects results in a tie of two or more projects, the Chief Expert will settle the tie with his vote.

Once the modules were selected, material preparations, marking possibilities and selection of marking groups will be conducted.

In the situation where the panel of Experts find the selected Test Project not suitable because of machining or marking scheme errors, the Test Project will be eliminated and a new vote takes place.

All Test Project proposals are made available to Experts on the WSI website at the conclusion of the Competition.

The Chief Expert coordinates the desired material requirements and the saw cutting possibilities with the Workshop Manager.

The aim of this Test Project selection method is:

Every Member has equal input in Test Project design;

This method ensures a balance of competences and industry needs from all Experts’

countries/regions;

Through the coordination of the Chief Expert it is ensured that all features and competences are

tested. This shall reflect a mix of the global training and/or manufacturing practices;

Coordination of tooling needs to minimize the amount of tools shipped by Competitors;

Coordinate material needs with the Host. Every Member knows what material and sizes to expect;

Each of the Test Project modules is validated by the machined sample brought by the Expert;

This ensures the machinability has been tested, the information on the blueprint is sufficient and

most important of all, there are sample parts for the programming of the coordinate measuring

machine;

The non-voted projects (blueprints and sample parts) may serve as display parts for the general

public visiting the venue.

The Competition Organizer will progressively update the Infrastructure List specifying the actual quantity, type, brand, and model of the items. Items supplied by the Competition Organizer are shown in a separate column.

At each Competition, the Experts must review and update the Infrastructure List in preparation for the next Competition. Experts must advise the Technical Director of any increases in space and/or equipment.

At each Competition, the Technical Observer must audit the Infrastructure List that was used at that Competition.

The Infrastructure List does not include items that Competitors and/or Experts are required to bring and items that Competitors are not allowed to bring – they are specified below.

8.2 MATERIALS, EQUIPMENT AND TOOLS SUPPLIED BY COMPETITORS IN THEIR TOOLBOX The Competitor must bring all equipment not provided for machining, measuring and testing as

required;

Competitors are to bring their own measuring tools;

To allow for innovation and learning from each other, the Competitor has no restrictions in

bringing any equipment or accessories, as long as it is conform to the provided equipment. Of

course it must be within reasonable limits … for example, Competitors shall not bring their

Tailstock or a Control-unit. In any debatable case the Chief Expert shall make the final decision;

Restriction of tools is limited to data transfer devices, as well as equipment that allows for pre-

setting and programming of tooling and offsets.

8.3 MATERIALS, EQUIPMENT AND TOOLS SUPPLIED BY EXPERTS Not applicable.

8.4 MATERIALS AND EQUIPMENT PROHIBITED IN THE SKILL AREA Tools and holders that allow for pre-programmed offsets are NOT allowed;

Any device that clearly reflects prior knowledge of the Test Project will be confiscated. This could be

for example a special sleeve that was manufactured specifically for the Test Project;

Individual data storage and data transfer devices are prohibited. Only the provided data storage

devices will be allowed.

8.5 PROPOSED WORKSHOP AND WORKSTATION LAYOUTS Workshop layouts from previous competitions are available at www.worldskills.org/sitelayout.

Example workshop layout:

The general layout of the workshop will be as below with sufficient space for the workstation, toolboxes and for the Competitor’s working area.

Please note that the following is an example of the layout, and is not definitive.

Approx. space for 20 Competitors = 1300m²

Space requirements: For two Competitors, one machine, one workbench and two programming stations: 6m x 8m = 48m²

Number of machines: Number of Competitors divided by two PLUS one.

Expert Room: approx. 6m x 4m = 24m²

Competitor Room: approx. 6m x 4m = 24m²

Sponsor Room: approx. 6m x 4m = 24m²

WM Room: approx. 6m x 6m = 36m²

CE Room: approx. 6m x 6m = 36m²

Space for Inspection equipment: 10m x 15m = 150m²

Space for Expert Work-group: (Tables and chair) approx. 120 m²

Space for a Band-Saw and Raw-Material: 6m x 10m = 60m²

Walking and working space between machines: Approx. 15m² per Competitor workstation

Add in some space for columns as well as Competitors toolboxes.

Add in min. of 1m clearance around the visitor-barrier.

Based on 20 Competitors, 20 Experts, Workshop Managers, Equipment Technicians and some Translators, the space would be approx. 1300 m² for the Competition.

9 VISITOR AND MEDIA ENGAGEMENT The following ideas may be considered to maximize visitor and media engagement.

The additional CNC machine could have a "phantom part" running so the audience can easily see

what CNC Turning does;

A display of industry parts where an industry professional provides explanation. The CNC machine

supplier could bring sample parts which they use at trade shows. Such display parts are easily

recognized and draw much attention.
