21.37 You will note that the values of a and b in Eq. (21.24) are higher for high-speed steels than for carbides. Why is this so? A simple expression for the mean temperature in turningon a lathe is given byTmean Vafb.(21.24)where V is the cutting speed and f is the feed of the tool,as shown in Fig. 21.2. Approximate values of the exponentsa and b are a = 0.2 and b = 0.125 for carbide tools anda = 0.5 and b = 0.375 for bigh-speed steel tools.

A simple expression for the mean temperature in turning on a lathe is given by Tmean x V°f%, (21.24) where V is the cutting speed and f is the feed of the tool, as shown in Fig. 21.2. Approximate values of the exponents a and b are a = 0.2 and b = 0.125 for carbide tools and a = 0.5 and b = 0.375 for high-speed steel tools.
