Which is the CORRECT equation for estimation of the tool life among the following, where T - tool life in minutes, V - cutting speed in m/min and C and n are constants?

Which is the CORRECT equation for estimation of the tool life among the following, where T - tool life in minutes, V - cutting speed in m/min and C and n are constants? Correct Answer VT<sup>n </sup>= C

Explanation:

Taylor’s tool life equation. 

  • Tool life of any tool for any work material is governed by machining parameters mainly cutting velocity (V), feed, and depth of cut (t). 
  • Cutting velocity affects the maximum and depth of cut minimum. 
  • Most widely used tool life equation and expressed in equation form

VTn = C

where V = Cutting velocity, T =Tool life (minutes), n = tool life exponent(generally 0.5-0.8), C = tool life constrant (Empirical)

5 taps are connected to a tank among which 3 taps (A, B and C) are inlet taps and 2 taps (P and Q) are outlet taps. A, B and C can fill the tank in 24 minutes, 30 minutes and 36 minutes respectively while taps P and Q can empty the tanks in 15 minutes and 45 minutes respectively. If tap B is opened after 5 minutes and tap P is opened 5 minutes after tap B, find the time taken to fill the tank completely.
Consider the following statements: 1. HSS tools wear very rapidly, whereas in cemented carbide tools, even though hardness is retained, crater wear can occur due to solid-state diffusion. 2. Cutting tools made of Super-HSS, also known as cobalt-based HSS, are made by adding 2% to 15% of cobalt which increases the cutting efficiency at heavier cuts by increasing the hot hardness and wear resistance. 3. Tools failure due to excessive stress can be minimized by providing small or negative rake angles on brittle tool materials, protecting tool tip by providing large side-cutting edge angles, and honing a narrow chamfer along the cutting edge. Which of the above statements are correct?
