CADCAM intro

What is CAD?

• An app that lets you analyze different design concepts

• A coding program to let you easily write in a computer language

• Computer software used to create 2D drawings/3D models of designs

• Creation and development for any robot

CAM stands for...

• Carefully Added Material

• Computer Aided Manufacture

• Computer Aided Making

• Careful Addition Manufacture

Which is the example of CAM machine?

• CATIA

• Thinkercad

• CNC

• Solidworks

3D printer is the example of

• cutting manufacturing technology

• additive manufacturing technology

• joining technology

• electronics technology

difference between CNC method and 3D printing is

• CNC is material removal method, 3D print is non material removal method

• 3D print is material removal method, CNC is non material removal method

• CNC is design making method, 3D print is manufacturing method

The model is developed using simple geometric forms or extrusions - such as cuboids, cylinders & prisms. These can be added or subtracted to produce complex 3D models.

the statement refers to......

• wireframe model

• surface model

• solid model

The 3D Computer Models shown in the figure is called

• solid model

• surface model

• wireframe model

this technique uses polymer sheet to build up rapid prototyping models

• Stereolithography (SLA)

• Selective Laser Sintering (SLS)

• Laminated Object Manufacturing (LOM)

• 3D Printing (3DP)

photosensitive polymer resins are widely used in ................................ rapid prototyping technique

• Fused Deposition Molding (FDM)

• Stereolithography (SLA)

• Selective Laser Sintering (SLS)

• 3D Printing (3DP)

What is the main disadvantage of CAM?

• Very expensive

• Unreliable accuracy

• Parts look unfinished

• Takes up too much space
