Excerpt from Installing, Maintaining, and Verifying Your Charpy Impact Machine This Special Publication is a reprint of nist Technical Note 1500-8, a TN series started by the Materials Reliability Division. This TN series describes their division's significant research accomplishments in measurement technol ogy, reported so that producers and users of materials can improve the quality and reliability of their products. This particular Practice Guide provides practical advice on how to correct problems discovered during the testing of Standard Reference Materials 2092, 2096, and 2098 on Charpy impact machines. Although only a small percent age of machines fail to meet the requirements during their annual performance tests, the failure of a machine can have large economic implications to the machine's owners, and we try to assist in correcting the problems. From the study of the fractured specimens and test data that are returned to nist for evaluation, we have learned how to identify many of the common problems. Also, over the years, we have had discussions with thousands of engineers and technicians at these companies, and have learned the most efficient sequences for identifying the sources of the problem and for correcting them. Now, we have collected and organized the various problems and solutions in this Special Publication. We hope that you will find it useful for installing a new machine correctly, and then for preparing for the annual verification tests.

The quality of the data developed by pendulum impact machines depends on how well the machines are installed, maintained, and verified. This is the reason that ASTM Standard E23 Standard Test Methods for Notched Bar Impact Testing of Metallic Materials specifies annual direct and indirect verification tests. Each year, NIST provides reference specimens for indirect verfication of over 1000 machines around the world. From evaluation of the absorbed energies and the fractured specimens, we attempt to deduce the origin of energies that are outside the ranges permitted by Standard E 23, and report these observations back to the machine owners. This recommended practice summarizes the bases for these observations, and hopefully will allow machines to be maintained at higher levels of accuracy. In addition, we provide details of the NIST verification program procedures and the production of the specimens.

Fundamentals of Machine Component Design presents a thorough introduction to the concepts and methods essential to mechanical engineering design, analysis, and application. In-depth coverage of major topics, including free body diagrams, force flow concepts, failure theories, and fatigue design, are coupled with specific applications to bearings, springs, brakes, clutches, fasteners, and more for a real-world functional body of knowledge. Critical thinking and problem-solving skills are strengthened through a graphical procedural framework, enabling the effective identification of problems and clear presentation of solutions. Solidly focused on practical applications of fundamental theory, this text helps students develop the ability to conceptualize designs, interpret test results, and facilitate improvement. Clear presentation reinforces central ideas with multiple case studies, in-class exercises, homework problems, computer software data sets, and access to supplemental internet resources, while appendices provide extensive reference material on processing methods, joinability, failure modes, and material properties to aid student comprehension and encourage self-study.

The second edition of Extrusion is designed to aid operators, engineers, and managers in extrusion processing in quickly answering practical day-to-day questions. The first part of the book provides the fundamental principles, for operators and engineers, of polymeric materials extrusion processing in single and twin screw extruders. The next section covers advanced topics including troubleshooting, auxiliary equipment, and coextrusion for operators, engineers, and managers. The final part provides applications case studies in key areas for engineers such as compounding, blown film, extrusion blow molding, coating, foam, and reprocessing. This practical guide to extrusion brings together both equipment and materials processing aspects. It covers basic and advanced topics, for reference and training, in thermoplastics processing in the extruder. Detailed reference data are provided on such important operating conditions as temperatures, start-up procedures, shear rates, pressure drops, and safety. A practical guide to the selection, design and optimization of extrusion processes and equipment Designed to improve production efficiency and product quality Focuses on practical fault analysis and troubleshooting techniques
