Opis: Metal Cutting Theory and Practice - John Agapiou, David Stephenson

A Complete Reference Covering the Latest Technology in Metal Cutting Tools, Processes, and Equipment Metal Cutting Theory and Practice, Third Edition shapes the future of material removal in new and lasting ways. Centered on metallic work materials and traditional chip-forming cutting methods, the book provides a physical understanding of conventional and high-speed machining processes applied to metallic work pieces, and serves as a basis for effective process design and troubleshooting. This latest edition of a well-known reference highlights recent developments, covers the latest research results, and reflects current areas of emphasis in industrial practice. Based on the authors' extensive automotive production experience, it covers several structural changes, and includes an extensive review of computer aided engineering (CAE) methods for process analysis and design. Providing updated material throughout, it offers insight and understanding to engineers looking to design, operate, troubleshoot, and improve high quality, cost effective metal cutting operations. The book contains extensive up-to-date references to both scientific and trade literature, and provides a description of error mapping and compensation strategies for CNC machines based on recently issued international standards, and includes chapters on cutting fluids and gear machining. The authors also offer updated information on tooling grades and practices for machining compacted graphite iron, nickel alloys, and other hard-to-machine materials, as well as a full description of minimum quantity lubrication systems, tooling, and processing practices. In addition, updated topics include machine tool types and structures, cutting tool materials and coatings, cutting mechanics and temperatures, process simulation and analysis, and tool wear from both chemical and mechanical viewpoints. Comprised of 17 chapters, this detailed study: * Describes the common machining operations used to produce specific shapes or surface characteristics * Contains conventional and advanced cutting tool technologies * Explains the properties and characteristics of tools which influence tool design or selection * Clarifies the physical mechanisms which lead to tool failure and identifies general strategies for reducing failure rates and increasing tool life * Includes common machinability criteria, tests, and indices * Breaks down the economics of machining operations * Offers an overview of the engineering aspects of MQL machining * Summarizes gear machining and finishing methods for common gear types, and more Metal Cutting Theory and Practice, Third Edition emphasizes the physical understanding and analysis for robust process design, troubleshooting, and improvement, and aids manufacturing engineering professionals, and engineering students in manufacturing engineering and machining processes programs. "This book covers the most important aspects about machining with grinding wheels and is an ideal handbook not only for beginners but also professionals in this area." -Professor from Saint Louis University, Missouri, USAIntroduction Scope of the Subject Historical Development References Metal Cutting Operations Introduction Turning Boring Drilling Reaming Milling Planing and Shaping Broaching Tapping and Threading Grinding and Related Abrasive Processes Roller Burnishing Deburring Examples Problems References Machine Tools Introduction Production Machine Tools CNC Machine Tools and CNC-Based Manufacturing Systems Machine Tool Structures Slides and Guideways Axis Drives Spindles Coolant Systems Tool Changing Systems Pallets Energy Use in CNC Machining Centers Examples References Cutting Tools Introduction Cutting Tool Materials Tool Coatings Basic Types of Cutting Tools Turning Tools Boring Tools Milling Tools Drilling Tools Reamers Threading Tools Grinding Wheels Microsizing and Honing Tools Burnishing Tools Examples Problems References Toolholders and Workholders Introduction Toolholding Systems Toolholder/Spindle Connections Cutting Tool Clamping Systems Balancing Requirements for Toolholders Fixtures Examples Problems References Mechanics of Cutting Introduction Measurement of Cutting Forces and Chip Thickness Force Components Empirical Force Models Specific Cutting Power Chip Formation and Primary Plastic Deformation Tool-Chip Friction and Secondary Deformation Shear Plane and Slip Line Theories for Continuous Chip Formation Shear Plane Models for Oblique Cutting Shear Zone Models Minimum Work and Uniqueness Assumptions Finite Element Models Discontinuous Chip Formation Built-up Edge Formation Examples Problems References Cutting Temperatures Introduction Measurement of Cutting Temperatures Factors Affecting Cutting Temperatures Analytical Models for Steady-State Temperatures Finite Element and Other Numerical Models Temperatures in Interrupted Cutting Temperatures in Drilling Thermal Expansion Examples Problems References Machining Process Analysis Introduction Turning Boring Milling Drilling Force Equations and Baseline Data Process Simulation Application Examples Finite Element Analysis for Clamping, Fixturing, and Workpiece Distortion Applications Finite Element Application Examples Examples Problems References Tool Wear and Tool Life Introduction Types of Tool Wear Measurement of Tool Wear Tool Wear Mechanisms Tool Wear--Material Considerations Tool Life Testing Tool Life Equations Prediction of Tool Wear Rates Tool Fracture and Edge Chipping Drill Wear and Breakage Thermal Cracking and Tool Fracture in Milling Tool Wear Monitoring Examples Problems References Surface Finish, Integrity, and Flatness Introduction Measurement of Surface Finish Surface Finish in Turning and Boring Surface Finish in Milling Surface Finish in Drilling and Reaming Surface Finish in Grinding Residual Stresses in Machined Surfaces White Layer Formation Surface Burning in Grinding Measurement of Surface Flatness Surface Flatness Compensation in Face Milling Examples Problems References Machinability of Materials Introduction Machinability Criteria, Tests, and Indices Chip Control Burr Formation and Control Machinability of Engineering Materials References Machining Dynamics Introduction Vibration Analysis Methods Vibration of Discrete (Lumped Mass) Systems Types of Machine Tool Vibration Forced Vibration Self-Excited Vibrations (Chatter) Chatter Prediction Vibration Control Active Vibration Control Examples Problems References Machining Economics and Optimization Introduction Role of a Computerized Optimization System Economic Considerations Optimization of Manufacturing Systems--Basic Factors Optimization of Machining Conditions Formulation of the Optimization Problem Optimization Techniques Examples Problems References Cutting Fluids Introduction Types of Cutting Fluids Coolant Application Filtering Condition Monitoring and Waste Treatment Health and Safety Concerns Dry and Near-Dry Machining Methods Test Procedure for Cutting Fluid Evaluation References Minimum Quantity Lubrication Introduction MQL System Types MQL Oils Machine Tools for MQL MQL Cutting Tools Thermal Management and Dimensional Control Air and Chip Handling MQL Research Areas References Accuracy and Error Compensation of CNC Machining Systems Introduction Machine Tool Errors Machine Tool Accuracy Characterization Machine Tool Performance Evaluation Method for Compensating the Dimensional Accuracy of CNC Machining System Examples References
