Edexcel GCSE Design and Technology key terms

A timber-based sheet material made by combining wood layers, particles or fibres, usually with adhesive.

A board made by bonding wood layers, fibres or particles together with adhesive.

Extra material allowed beyond the finished dimensions for cutting, trimming or other manufacturing needs.

The ability to make a product using the available equipment, processes, skills and production capacity.

The expense of converting material into a finished product, including machinery, setup, labour and energy.

An operation used to turn material into a component or product, such as cutting, planing, shaping or joining.

A document giving the materials, dimensions, processes, equipment and checks needed to make a product.

The proportion of manufactured products that meet the required quality standards.

A short, sharp steel pin with a small round plastic head, pushed through paper or card into a backing that grips its shaft; the head holds the material against the backing temporarily.

The potential of a product to attract its intended customers and sell successfully at an appropriate price.

The price at which a material is bought and sold in a market; it can change as market conditions change.

Drawing or indicating the positions of features, lines or cuts on a material before making a product.

A patterned film that controls which areas of photoresist receive light during exposure.

Manufacture of very large quantities of standardised products over an extended period to meet widespread demand.

The expense of buying the material needed to make a product.

A version of a material supplied with particular properties and a specified level of performance.

A measurable or observable characteristic of a material that affects its suitability for a product, such as strength or resistance to corrosion.

How well a material’s condition and properties meet the requirements of its intended application, including strength, appearance and freedom from unacceptable defects.

A manufacturing process that cuts or abrades unwanted material away from a starting piece to produce the required shape and size.

Sorting or taking apart a product so that its different materials can be collected and processed separately.

The surrounding material in a composite that binds and protects the reinforcement and transfers loads to it.

Medium-density fibreboard: a manufactured board made from fine wood fibres bonded with adhesive and compressed into sheets.

The ratio of output load force to input effort force: $\text{MA}=\frac{\text{load}}{\text{effort}}$. It has no unit.

A component, such as a nut or bolt, used to hold parts together mechanically rather than by adhesive bonding.

A physical fastener, such as a screw or nail, that holds components together.

An assembly of moving parts that transmits or changes motion and forces.

A manufactured board made from fine wood fibres compressed and bonded with resin adhesive.
