Benefits of CAD, CAM and CNC

Question 1

What is CAD

Answer 1

Computer Aided Design is the use of computer software to design and create 2D and 3D design ideas, models and prototyping, eg SolidWorks

Question 2

What are the advantages of CAD

Answer 2

-All of the required features are set within the programme, eg extrusion, filleting
-Both 2D and 3D drawings can be easily created by the product designer to show clients
-Scaling is not required as drawings care created in full size and features like zooming can be used for clarity by the designer
-Details of the production methods can be taken from the programme

Question 3

What is Computer Aided Manufacturing

Answer 3

A system of using computer technology to aid the manufacturing process

Question 4

What are the benefits of CAM

Answer 4

-Very efficient as it produces products/ components quicker
-cost effective overtime- reduction in labour costs
-can create complicated products/ components of a unique shape with unform repeatability
-Can speed up production of low volume products

Question 5

What are the benefits of CNC

Answer 5

-Can be continuously used 24 hours a day, 365 days a year and only need to be switched off for occasional maintenance
-Modern design software allows the designer to stimulate the manufacture of his/ her idea. This saves time and money
-Less skilled/ trained people can operate CNCs unlike manual lathes/ milling machines which need skilled engineers
