What is CAM• What Does CAM Stand for ?

– It is (Computer Aided Manufacturing)

• What is it ?

– Translate CAD model into Machine Codes – Help to decide the machine strategies – Help to decide the tools selection, Feed, Speed

parameters – Simulate the cutting Process

Steps to CAM Process• Design for CNC – Thinking and Planning for

manufacturing the parts• CAD – Need a Solid or Surface model

• CAM- Converting Model into Machine language – Selection of Machining Process – Selection of Features

– Selection of tools, Feed speed parameters – Selection of Strategy

• Machining- Manufacturing the Part

Selection of Tools and CuttingParameters

• Roughing, Semi-finish and finishing Tool – END Mill

• High Speed Steel• Solid Tungsten Carbide Tools (For High Production, Costly)

• Finishing Tool – Ball/Bull Nose End Mill

• High Speed Steel• Solid Tungsten Carbide Tools

• Speed, Feed and Depth of Cut Selection
