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.

New cards
86

New cards
89

What does CFD stand for?

Computational Fluid Dynamics

New cards
90

What does FEA stand for?

Finite Element Analysis

New cards
91

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.

New cards
92

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.

New cards
93

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.

New cards
94

What does FDM stand for?

Fused Deposition Modelling

New cards
95

What does EPOS stand for?

Electronic Point Of Sale

New cards
96

What is EPOS used for?

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

New cards
97

What does PPC stand for?

Production, Planning and Control

New cards
98

What does MPS stand for?

Master Production Schedule

New cards
99

How can a MPS be useful?
