1. Interpreting and Using Engineering Information

2. Overview This unit aims to give learners the knowledge and skills needed to use engineering information such as drawings and working instructions to carry out manufacturing or engineering process operations.

3. Learning Outcomes On completion of this unit a learner should: 1. Know how to interpret drawings and related documentation 2. Be able to use information from drawings and related documentation.

4. Learning Outcome 1 Information: materials or components eg location/orientation of parts, connections to be made, circuit characteristics (pressure, flow, current, voltage, speed); dimensional detail eg imperial and metric systems of measurement, physical dimensions, tolerances, fixed reference points, surface texture; manufacturing/production detail eg processes or treatments, assembly sequence or installation requirements; symbols and abbreviations eg surface finish, electronic components, weld symbols, linear and geometric tolerances, pressure and flow characteristics, torque values Engineering drawings: working drawings eg component, general assembly/sub-assembly, fabrication, welding, repair/modification, fluid power, installation, wiring/circuit diagrams; graphical representations eg sketches, schematic diagrams, flow charts, physical layout diagrams, illustrations from manufacturers’ manuals Related documentation: working instructions eg operation sheets/job cards, test schedules, manufacturers’ manuals for assembly/test/installation, weld procedure specifications; quality control information eg national, international and organisational standards, reference tables/charts Tasks: relevant to a manufacturing or engineering process operation eg product manufacture or modification, equipment installation or repair, system or service planning Other information: sources relevant to task eg electronic component pin configuration specifications, standard reference charts for limits and fits, tapping drill reference charts, bend allowances required for material thickness, metal specifications, manufacturers’ data for the use of welding rods/bonding/finishing materials

5. Learning Outcome 2 Work output: manufacturing or engineering process operation eg product manufacture/assembly/design, maintenance planning or procedure Production documentation: relevant to manufacturing or process operation eg job cards, test reports, quality control documentation Drawing and document care and control: location and security eg storage conditions, access points and return procedures, reporting discrepancies in data and documents; physical handling eg damage and effects from graffiti, cleanliness, folding methods; document control eg issue and amendment dates, part/ pattern numbers, reporting of loss/damage
