engineering recuitment GATE ME 2023-24 Test Series Production Engineering (Manufacturing) Machining Processes and Machine Tools Taylor's Tool Life Equation
For machining a piece of metal, the tool life varies according to speed of cutting and is given as follows:
|
Speed (m/min) |
90 |
70 |
|
Tool life (min) |
75 |
140 |
Then, the total life exponent (n) and constant (c) will be respectively
1
0.4; 572
2
0.4; 506
3
0.5; 572
4
0.5; 506
