Edmund Isakov - Böcker

OverviewInternational System of Units (SI) (Print On-Demand Edition) is a one-of-a-kind book. It provides detailed information on the metric system, its origin, history, and how the base and derived units were established.  The book has four chapters (Measurement Systems, the International System of Units, Metrication in the United States, and United States Metric Association), appendices, an afterword, and references. The book is principally aimed at educating students in the United States, but it will also be of interest to anyone who enjoys the popular sciences.This is a Print-On-Demand title. It has a CD-ROM companion (ISBN 978-0-8311-3466-2) for which publication has ceased.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). He is known for his work in research, development and applications of cuttting tools for milling, turning and boring. Dr. Isakov has authored Mechanical Properties of Work Materials and numerous 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. during nearly two decades at Kennametal, Inc., he became a noted authority on the technical analysis of cutting tools. Dr. Isakov is now an independent consulant and manufacturing sciences writer based in Florida. He is a senior member of SME.IntroductionChapter 1: Measurement SystemsBrief history of the English SystemBrief history of the Metric SystemChapter 2: International System of Units (SI)SI Base Units of MeasurementSI Derived Units of MeasurementChapter 3: Metrication in the United StatesBrief historyCurrent usage of the metric unitsChapter 4: United States Metric Association (USMA)USMA establishmentBrief historySummary of metric usage in the United StatesAppendix 1: Signatories to the Meter Convention (Treaty of the Meter)Appendix 2: Associate States of the CGPMAppendix 3: CGPM MeetingsAppendix 4: Prefixes for Multiples and Submultiples of the SI unitsAppendix 5: Medals awarded to scientists, after whom the units of measurement are namedAppendix 6: Standard Inductor ValuesAppendix 7: The Sixteen Bronze StatuesAppendix 8: Temperature Conversion FormulasReferencesIndex – Biographical Names

Maximize the productivity of cutting.   Linear regression equations for converting Rockwell, Vickers, Knoop, and Scleroscope hardness numbers into Brinell hardness numbers.Formulas and linear regression equations for calculating ultimate tensile strength of the most commonly used work materials in relationship with their hardness.Formulas for calculating the number of inserts simultaneously engaged with the workpiece depending on milling conditions.Formulas to calculate machining time when facing, cutoff, and deep grooving and for feed and radial forces in relationship with tangential force.Set of formulas to calculate overhang of boring bars made of tungsten heavy alloys and cemented carbides in comparison with a boring bar made of steel.Formulas for metal removal rate and for calculating tangential and axial forces.Establishes power constant values for most commonly used work materials.A unique and handy resource, Engineering Formulas for Metalcutting will enable users to calculate necessary speeds, feeds, and required machining power in order to maximize the productivity of cutting. Providing information on formulas and their applications in a concise and clearly arranged format, it describes mechanical properties of the most popular work materials, such as steels, cast irons, and nonferrous alloys. And it offers numerous formulas for calculating speeds, feeds, cutting forces, and machining power. What's more, practical examples of calculating the variety of such cutting parameters will make this a valuable source of knowledge in training and practice.

Material removal operations are among the most expensive; in the U.S. alone, more than $100 billion were spent on machining in 1999. These high costs put tremendous economic pressures on production managers and engineers as they struggle to find ways to increase productivity.Machining recommendations provided in this book cover turning since it allows removing more material per unit of time and consuming more power at the roughing operations than end milling, boring or 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 the most commonly used grades of carbon, alloy, stainless, tool, and maraging steels. Cutting tool materials are cemented carbides, cermets, and ceramics.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.
