Find speed for two hours with HSS tools

Find speed for two hours tool life for dry machining of free cutting mild steel with HSS tool.

Solution

From Table 3, a value of C = 74 m/min is chosen while for HSS tool a mean value of n = 0.125 has been assumed.

V tⁿ = C

V = C /t ⁿ

= 74 /120^0.125

= 74 /1.82

= 40.67

= 40.67 metres/minute

Table 3: Constant C for Taylor's Equation
