Digital Design and Manufacture

What does CAD stand for?

What does CAD stand for?

Computer Aided Design.

What can CAD do?

Develop 2D and 3D drawings that can be used for CNC machines.

What does CAM stand for?

Computer Aided Manufacture.

What is a simulation?

For example, considering F1. Instead of driving those million$ cars and possibly crashing those while simply just practicing the use of a simulation to keep the car and the driver safe is done entirely virtually acting almost like a prototype compared to the real thing.

But an example considering CNC, CAM and CAD would consider this useful by using a simulation to simulate possibly how long it might take for a CAM to complete a job etc.

What does CNC stand for?

Computer Numerically Controlled.

What are some machines that can use CNC intervention?

CNC (Computer Numerically Controlled)

• Laser Cutting

• Routing

• Milling

• Turning

• Plotter Cutting

What is Virtual Modelling?

A form of simulation where use of 3D CAD allows for creating design prototypes entirely free and online.

An example of this that you may have used is Sketchup.

What does CFD stand for?

Computational Fluid Dynamics

What does FEA stand for?

Finite Element Analysis

What can CFD be used for?

Considering F1 they make use of wind tunnels in order to help perfect the way wind is manipulated around the cars allowing for a higher edge due to hopefully less wind resistance. However, these real wind tunnels are not cheap so the use of realistic CFD programs allows for the same job but cheaper.

CFD (Computational Fluid Dynamics) - A feature possibly available in a simulation program.

What does FEA do?

Looking at F1 the making of the car considers many parts especially looking at weight as those cars act with multiple G’s going around corners so if one singular place in the car can’t withstand the force it could lead to it entirely obeying the forces which is where FEA comes in.

Once again being another feature which would be found virtually in a simulation program the addition of FEA (Finite Element Analysis) looks at stress, vibrations and forces and how strong they might act on parts and components.

How is rapid prototyping possible?

Due to the efficient and high-quality abilities brought by CNC machines this easily allowed for quick well made protoypes to be made.

What does FDM stand for?

Fused Deposition Modelling

What does EPOS stand for?

Electronic Point Of Sale

What is EPOS used for?

For Data collection allows for it to be recorded easily after a product is bought from a consumer automatically.

What does PPC stand for?

Production, Planning and Control

What does MPS stand for?

Master Production Schedule

How can a MPS be useful?

A Master Production Schedule is what’s personally responsible for making sure the entire production process runs smoothly from supplying to selling.

How are computers used considering PPC?

Computers in PPC control:

• Plan and Control Production

• Organisation of Materials and Components

• Co-ordination of Suppliers and Components

What is a Kanban?

A Monitoring, Re-Ordering central system for JiT Production.
