.... In such conditions, strain rates in the primary shear zone lie from 10 3 to 10 5 [ 14 ], although in high speed machining the strain rate can reach 10 7 or higher [ 15 ]. Exact values of strain rate are difficult to measure; however, it is clear that chip compression ratio and cutting speed strongly influence...

.... Despite these advances in near-net shape processing, machining plays a vital role in superalloy part manufacture. Much of the high machining cost is due to the fact that allowable cutting speeds for superalloys are only 5 to 10% of those used for steel. Surface condition, particularly after machining...
