Repeat the calculations in Example 15.4 for stainless steel instead of cast iron. Use the same material dimensions and operating conditions, and compare the machining times for the two materials.
Example 15.4
A flat piece of cast iron 4.0 inches wide and 15. inches long is to be milled with a feed rate of 20. inches/minute with a depth of cut of 0.10 inches. The milling cutter rotates at 100. RPM, and is wider than the workpiece. Determine:
1. the material removal rate
2. the machining power required
3. the machining torque required
4. the time required to machine the workpiece
