1

Conventional machining

Sharp cutting tool is used to mechanically cut the material to desired geometry

2

Abrasive process

Mechanically remove material using hard abrasive particles

3

Material Removal Process

Family of shaping operations in which excessive material is removed from starting work part so that what remains is desired final geometry

4

Nontraditional Processes

Processes which use other forms other than cutting tool and abrasive particles to cut away material to remove material

5

machining

manufacturing process in which sharp cutting tool is used to cut away material to leave desired part shape

6

Advantages of machining

  • Variety of work material
  • Variety of part shapes and geometric features
  • Dimensional accuracies
  • Good Surface Finish

7

Disadvantages of machining

  • wasteful of materials
  • time consuming

8

Cutting speed

primary motion in machining

 

 

9

Feed

Secondary motion in machining

10

Turning

Machine Operation where a cutting tool with a single cutting edge is used to remove material from rotating workpiece to generate a cylindrical shape

 

Speed motion provided by rotating workpat and feed ktion provided by cutting tool moving slowly in direction parallel to axis of rotation of workpiece

11

Drilling

Machining operation used to create holes

 

Accomplished by rotating tool that typically has two cutting edges.  Tool fed in direction parallel to its axis of rotation

12

Milling

Machining operation where rotating tool with multiple cutting edges is fed slowly across work material to generate a plane or straight surface

 

Direction of feed is perpendicular to tool's axis of rotation

13

rake angle

Rake ace us oriented at a certain angle known as rake angle

14

rake face

directs the flow of the newly formed chip

15

relief angle

Angle that orients the flank surface

16

Basic types of cutting tools

a) single point tool

 

b) multiple point cutting edge tools

17

single point tools

has one cutting edge and and is used for operations such as turning

18

multiple cutting edge tool

Have more than one cutting edge and usually achieve their motion relative to the workpart by rotating

 

Includes drilling and milling
