Vibrations in Metal Cutting Measurement, Analysis and Reduction
Vibrations in Metal Cutting Measurement, Analysis and Reduction Linus Pettersson Ronneby, March 2002 Department of Telecommunications and Signal Processing Blekinge Institute of Technology 372 25 Ronneby, Sweden c Linus Pettersson Licentiate Dissertation Series No. 01/02 ISSN 1650-2140 ISBN 91-7295-008-0 Published 2002 Printed by Kaserntryckeriet AB Karlskrona 2002 Sweden v Abstract Vibration and noise in metal cutting are ubiquitous problems in the workshop. The turning operation is one kind of metal cutting that exhibits vibration related problems. Today the industry aims at smaller tolerances in surface finish. Harder regulations in terms of the noise levels in the operator environment are also central. One step towards a solution to the noise and vibration problems is to investigate what kind of vibrations that are present in a turning operation. The vibrations in a boring operation have been put under scrutiny in the first part of this thesis. Analytical models have been compared with experimental results and the vibration pattern has been determined. The second part of the thesis deals with active vibration control in external turning operations. By embedding a piezo-ceramic actuator and an accelerometer into a tool holder it was possible to obtain a solution that can be fitted in a standard lathe. The control system consists of the active tool holder, a control system based on the filtered-X LMS algorithm and an amplifier designed for capacitive loads. The vibration level using this technique can be reduced by as much as 40 dB during an external turning operation. vii Preface The work presented in this licentiate thesis has been performed at the department of Telecommunications and Signal Processing at Blekinge Institute of Technology. -
Mechanical Metalworking: from Manual to Computer-Based Processes
August 04, 2021 Mechanical metalworking: from manual to computer-based processes Just like in an ordinary kitchen, there is more to the steelmaker’s kitchen than just the processes where high temperature plays a crucial role, such as boiling, roasting or baking. Before a dish can be served, it needs additional work to make it more appealing. The same is true of metals. Prior to their use, plates, tubes, rods and complex steel castings are subject to cold forming by special metalworking machines and lathes, which become more and more sophisticated each year. History of mechanical metalworking Let’s look first into the history of mechanical metalworking and its origins. Unlike many other processes that are unique to steelmaking, some ideas related to the mechanical working of metal surfaces came from related areas. The ancient Egyptians had devices for drilling holes in stones. Wood machining equipment that later evolved into turning lathes existed in the sixth and seventh centuries BC. Yet these types of processes were not applied to metals for hundreds of years. For a long time, metal surface treatment had several restricting factors. First, it required harder tools. Second, small-batch production did not need high-precision metalworking. Third, the industrial revolution and mass production of uniform products only became a reality in the 18th-19th centuries. The third reason was a key prerequisite for the appearance of mechanical metalworking. Smiths that made goods for individual orders gave way to large industrial manufacturers and factories that had the capacity to produce large quantities of uniform metal goods. Gunsmiths were among the first to appreciate the importance of standardised metalworking. -
DRAFT – Subject to NIST Approval 1.5 IMPACTS of AUTOMATION on PRECISION1 M. Alkan Donmez and Johannes A. Soons Manufacturin
DRAFT – Subject to NIST approval 1.5 IMPACTS OF AUTOMATION ON PRECISION1 M. Alkan Donmez and Johannes A. Soons Manufacturing Engineering Laboratory National Institute of Standards and Technology Gaithersburg, MD 20899 ABSTRACT Automation has significant impacts on the economy and the development and use of technology. In this section, the impacts of automation on precision, which directly influences science, technology, and the economy, are discussed. As automation enables improved precision, precision also improves automation. Followed by the definition of precision and the factors affecting precision, the relationship between precision and automation is described. This section concludes with specific examples of how automation has improved the precision of manufacturing processes and manufactured products over the last decades. 1.5.1 What is precision Precision is the closeness of agreement between a series of individual measurements, values, or results. For a manufacturing process, precision describes how well the process is capable of producing products with identical properties. The properties of interest can be the dimensions of the product, its shape, surface finish, color, weight, etc. For a device or instrument, precision describes the invariance of its output when operated with the same set of inputs. Measurement precision is defined by the International Vocabulary of Metrology [1] as the "closeness of agreement between indications obtained by replicate measurements on the same or similar objects under specified conditions." In this definition, the "specified conditions" describe whether precision is associated with the repeatability or the reproducibility of the measurement process. Repeatability is the closeness of the agreement between results of successive measurements of the same quantity carried out under the same conditions. -

Manufacturing Glossary
MANUFACTURING GLOSSARY Aging – A change in the properties of certain metals and alloys that occurs at ambient or moderately elevated temperatures after a hot-working operation or a heat-treatment (quench aging in ferrous alloys, natural or artificial aging in ferrous and nonferrous alloys) or after a cold-working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but never involves a change in chemical composition of the metal or alloy. Abrasive – Garnet, emery, carborundum, aluminum oxide, silicon carbide, diamond, cubic boron nitride, or other material in various grit sizes used for grinding, lapping, polishing, honing, pressure blasting, and other operations. Each abrasive particle acts like a tiny, single-point tool that cuts a small chip; with hundreds of thousands of points doing so, high metal-removal rates are possible while providing a good finish. Abrasive Band – Diamond- or other abrasive-coated endless band fitted to a special band machine for machining hard-to-cut materials. Abrasive Belt – Abrasive-coated belt used for production finishing, deburring, and similar functions.See coated abrasive. Abrasive Cutoff Disc – Blade-like disc with abrasive particles that parts stock in a slicing motion. Abrasive Cutoff Machine, Saw – Machine that uses blade-like discs impregnated with abrasive particles to cut/part stock. See saw, sawing machine. Abrasive Flow Machining – Finishing operation for holes, inaccessible areas, or restricted passages. Done by clamping the part in a fixture, then extruding semisolid abrasive media through the passage. Often, multiple parts are loaded into a single fixture and finished simultaneously. Abrasive Machining – Various grinding, honing, lapping, and polishing operations that utilize abrasive particles to impart new shapes, improve finishes, and part stock by removing metal or other material.See grinding.
