Key Principles and Methodologies in Engineering and Manufacturing Design

This set of flashcards covers key principles, types of manufacturing processes, and methodologies relevant to engineering and manufacturing design, based on the lecture notes provided.

What is the fundamental goal of a manufacturing process?

To produce a product that has a useful form.

What are the three stages in the manufacturing process?

1. Change the physical properties of raw material, 2. Change the shape and size of the workpiece, 3. Achieve the required dimensional accuracy and surface finish.

What are some key types of manufacturing processes?

Forming, Shaping, Finishing, Casting, Additive, Joining, and Wasting.

What is forming in manufacturing?

A mechanical process used to change the size and shape of a workpiece.

How does casting work in manufacturing?

Molten material is poured into a mould that contains a hollow cavity of the required shape.

Describe additive manufacturing.

A form of industrial 3D printing that creates objects by adding materials layer by layer.

What differentiates expendable mould processes from permanent mould processes in casting?

Expendable mould processes destroy the moulds to remove the casting, while permanent mould processes reuse the mould.

What are the two main categories of finishing processes?

Removing and reshaping, and Adding and altering.

What is the purpose of powder techniques in shaping processes?

To produce a shape by compacting a powder.

What is wasting in manufacturing?

The process of cutting away material that produces waste.

Give an example of a wasting process.

Guillotining, drilling, laser cutting, or CNC routing.

What is the significance of dimensional accuracy in manufacturing?

It ensures parts fit together properly and function as intended.

What is the role of joining processes in manufacturing?

To assemble individual parts into larger components or assemblies.

List two examples of shaping processes.

Casting and cutting/grinding.

What is the function of additive manufacturing in product design?

To create new products with minimal waste and lower material costs.

What does the term 'sintering' refer to in additive manufacturing?

The process of compacting and forming material by heat or pressure.
