Cutting Data for Turning of Steel is about machining, one of the most important manufacturing processes. Machining is subtractive — it removes unwanted material in the form of chips from a workpiece. Material removal operations are among the most expensive.

In the United States alone, billions are spent on machining every year, and high costs put tremendous economic pressures on production managers and engineers as they struggle to find ways to increase productivity. This book provides machining recommendations for removal of more material per unit of time. It also helps improve power consumption at the roughing operations, as well as in end milling, boring, and drilling.

Machining recommendations relate to cutting speeds, feed rates, and depth of cuts. Such recommendations depend on the workpiece material properties and the cutting tool material. Workpiece materials described in this book are commonly used grades of carbon, alloy, stainless, tool, and maraging steels. Cutting tool materials include cemented carbides, cermets, and ceramics.

Features

• Describes hardness, tensile strength, and machinability of steels-the major mechanical properties. These properties are taken into consideration when selecting machining parameters.
• Features machining recommendations for turning that provide the cutting speed values based on Brinell hardness numbers, the depth of cut, and feed rate in relationships with the type of steel.
• Summarizes numerous calculations in five appendices.

Dr. Edmund Isakov. Ph.D., has enjoyed a long and distinguished career in metalworking. He earned his Doctor of Philosophy degree in Mechanical Engineering at the V. Bakul Institute for Superhard Materials (Kiev, Ukraine). During nearly two decades at Kennametal, Inc., he became a noted authority on technical analysis of cutting tools. Known for his work in research, development, and applications of cutting tools for milling, turning, and boring, Dr. Isakov has authored books, articles, and papers on metalcutting. He holds several U.S. patents and numerous U.S.S.R. Inventor’s Certificates pertaining to carbide and diamond tools. A senior member of SME, he is now an independent consultant and manufacturing sciences writer based in Florida.
