DT Flashcards
Information sources which display a range of typical engineering information, such as feed rates for cutting various materials, tapping drill sizes, thread details and finishing detail, etc
Data sheets
These are views that focus on a particular part of an engineering drawing, often used to enlarge complex parts of a design or engineering drawing
Detail views
For the purpose of this qualification, engineering drawings are the drawings that are issued to learners in the Unit 1 controlled assessment brief that will enable them to accurately manufacture the required product from the given brief and specification. Learners are also required to produce their own engineering drawings as a part of their response for the controlled assessment brief for Unit 2
Engineering drawing
A measured three-dimensional view or representation of a part or product. They are constructed using 30• or (30•/60•) grids
Isometric drawing
Specific instructions that explain the task/job to be done. These are completed after the work is complete and the sheets are updated based on the work undertaken
Job sheets
Contains all the information that is needed to make the product. It describes the stages of manufacture and the materials needed, using flow charts, diagrams, notes and samples
Manufacturing specification
These are the sizes that materials are generally sold in from a supplier. They form the starting point of where components or parts are manufactured from in the workshop
Material stock sizes
This is the standard set of views used in an engineering drawing to display sizes and details about a product. Typically, views would include a front, end (side,sometimes left and right) and a plan (top) elevation (or views)
Orthographic projection
A series of documents provided to an engineer to assist in the designing or manufacturing is a product
Planning documentation
A document that focuses on the potential for accidents and harm and puts into place mitigations to prevent accidents and unsafe working practices based on the severity of risk
Risk assessment
These are detailed drawings showing a ‘cut through’ of a product or component. It allows details of items such as gaskets, seals and springs to be clearly shown
Sectional view
These are the standard conventions used in laying out an engineering drawing (see orthographic drawing) as laid out under British standards (BS8888)
Third angle projection
Should be present on all engineering drawings and should give additional information about what is on the sheet. They include details such as plan number, number of sheets, dates and names of who created and checked the sheet when, in what scale the drawing is, the tolerances, etc. Title blocks can also give information on materials, finishes, etc
Title block
This is the maximum and minimum (+/-) allowance that a manufactured part/ component can be off from the stated size on a drawing
Tolerance
Designers and Engineers use anthropometric data to help make sure a product will be comfortable for the user
Anthropometrics
BS 8888 is the UK’s national framework standard for engineering drawings
BS8888 Conventions
These are printed or digital outcomes which show a pictorial representation of the final engineering solution
CAD Visuals
Any reference point of known or assumed coordinates from which calculation or measurements may be taken
Datum Points
A branch of science that aims to learn about human abilities and limitations, and then apply this learning to improve peoples interaction with products, systems and environments
Ergonomics
