This should be a document to guide the manufacturers on how to produce the engineered product, as well as providing specification points that must be met during, and at the end of manufacture.  \nParts of the information may already be given on sections of drawings from sketch sheets and testing outcomes however, the manufacturing specification pulls all of this information together into a concise document, making it easier to find key information. For example:  \nMaterials information should be included to inform the manufacturer what materials each part should be made from. This may include stock material as well as any additional details about quality, etc.  \nTechnical details should include details of any components used as well as specific tolerances linked to finished parts. This section should also identify bought in parts such as fixings, hinges, brackets, etc.  \nFinishing details focuses on the type of finish applied to each manufactured part, these could be machine finishes such as knurling or polishing or applied finish such as anodising or spray painting. Other finishes, such as printing or spark eroding, could also be covered here.  \nDrawing an engineering design to standards  \nEngineering drawings are used to provide all of the details for items tobe manufactured in all areas of design and engineering.  \nEngineering drawings must follow a set of conventions laid out by British standards and these dictate the way that the drawings should be laid out, dimensioned, what scales should be used as well as the types of lines to be used to depict certain views and actions.  \nIn the United Kingdom, designers and engineers use the third angle projection method to layout their information on plans and drawings. Drawings undertaking using traditional drawing boards must follow the same conventions as those drawn on CAD (computer aided design) using PC’s.  \nLine weights in engineering drawings also follow British standards and should again be used in traditional and CAD work.  \nIsometric drawings should be used to illustrate an accurate threedimensional representation of the part of product. Lines are set up on 30° angles using an isometric grid.  \nAssociate symbols on drawings, including:  \n• Dimensions and associated symbols:  \nо diameter: the size of a line that runs from one side of a circle, through the centre to the opposite side  \nо circumference: the perimeter of a circle or ellipse  \nо radius: half of the diameter  \nо height, depth and width.  \n• Conventions, such as:  \nо title block: gives additional information on a drawing such as scale, name and title  \nо dimension lines: the actual sizes on an engineering drawing о extension lines: continue or extend from the surface of the  \nobject and establish the size of the dimension о centre lines: show the exact centre of a circle or arc  \nо metric: units of measurements to be used.","cbCaibb5esBsiRVL","https://ap.wps.com/l/cbCaibb5esBsiRVL","pdf",346248,"English","# Producing a manufacturing specification\n## Materials information\n## Technical details and tolerances\n## Finishing details\n# Drawing an engineering design to standards\n## British standards conventions\n## Third angle projection\n## Line weights\n## Isometric drawings\n## Associated symbols and conventions","[{\"question\":\"What is the purpose of a manufacturing specification in engineering design?\",\"answer\":\"A complete manufacturing specification guides manufacturers on how to produce the engineered product and lists specification points that must be met during and at the end of manufacture.\"},{\"question\":\"What sections should be included in a manufacturing specification?\",\"answer\":\"It should include materials information, technical details with specific tolerances (including bought-in parts), and finishing details describing the required surface processes and finishes.\"},{\"question\":\"Which standards and drawing conventions are required for engineering drawings in the UK?\",\"answer\":\"Engineering drawings must follow British standards conventions, including layout, dimensioning, scales, line types, third angle projection, and British standard line weights for both traditional and CAD work.\"}]","WJEC Level 1-2 Engineering Unit 2 - Communicating an engineering design solution - Producing a manufacturing specification | PDF"]
