This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Leveraging the similarities between additive and traditional subtractive machining path, an alternative path planning method designed upon an existing commercial CAM software framework to develop additive operations is proposed. Considering additive machining path as the inverse of traditional subtractive machining path, additive path generation strategies using path reversed traditional machining approaches such as pocketing and spiral contouring are explored. Also proposed is a method of preoperative additive process parameter control that uses virtual machining simulation to collect volumetric data from additive path in a subtractive machining configuration. The control method equates the material removal along the subtractive path with the volumetric material to be deposited in the additive path configuration. Using the volumetric data from virtual machining simulations and empirical data from deposition experiments, process parameter values are modulated along the additive path to achieve dynamic control of the volumetric deposition rate. Path planning strategies involving dynamic process parameter control are then proposed and tested using object geometry of increasing complexity. Selective DED consisting of the cycling, ON/OFF, of laser power during deposition to fabricate an object, and applications of trochoidal DED path are also studied. The strategies proposed are integrated as add-in to an existing commercial CAM software and are then demonstrated through the fabrication of objects using a 5-Axis DED Hybrid machining center. The benefits of the proposed CAMAM methodology allow for rapid integration of additive capabilities into existing commercial CAM software and the addition of deposition preoperative control to the additive path planning process. The addition of these capabilities introduces path planning methods that address the fabrication of freeform deposition layers and provides means for additive DED path creation in the simultaneous 5-axis configuration.

Download or read book Additive Manufacturing of Titanium Alloys written by Bhaskar Dutta and published by Butterworth-Heinemann. This book was released on 2016-06-17 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive Manufacturing of Titanium Alloys: State of the Art, Challenges and Opportunities provides alternative methods to the conventional approach for the fabrication of the majority of titanium components produced via the cast and wrought technique, a process which involves a considerable amount of expensive machining. In contrast, the Additive Manufacturing (AM) approach allows very close to final part configuration to be directly fabricated minimizing machining cost, while achieving mechanical properties at least at cast and wrought levels. In addition, the book offers the benefit of significant savings through better material utilization for parts with high buy-to-fly ratios (ratio of initial stock mass to final part mass before and after manufacturing). As titanium additive manufacturing has attracted considerable attention from both academicians and technologists, and has already led to many applications in aerospace and terrestrial systems, as well as in the medical industry, this book explores the unique shape making capabilities and attractive mechanical properties which make titanium an ideal material for the additive manufacturing industry. - Includes coverage of the fundamentals of microstructural evolution in titanium alloys - Introduces readers to the various Additive Manufacturing Technologies, such as Powder Bed Fusion (PBF) and Directed Energy Deposition (DED) - Looks at the future of Titanium Additive Manufacturing - Provides a complete review of the science, technology, and applications of Titanium Additive Manufacturing (AM)

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Download or read book Climate Impacts on Energy Systems written by Jane O. Ebinger and published by World Bank Publications. This book was released on 2011 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: "While the energy sector is a primary target of efforts to arrest and reverse the growth of greenhouse gas emissions and lower the carbon footprint of development, it is also expected to be increasingly affected by unavoidable climate consequences from the damage already induced in the biosphere. Energy services and resources, as well as seasonal demand, will be increasingly affected by changing trends, increasing variability, greater extremes and large inter-annual variations in climate parameters in some regions. All evidence suggests that adaptation is not an optional add-on but an essential reckoning on par with other business risks. Existing energy infrastructure, new infrastructure and future planning need to consider emerging climate conditions and impacts on design, construction, operation, and maintenance. Integrated risk-based planning processes will be critical to address the climate change impacts and harmonize actions within and across sectors. Also, awareness, knowledge, and capacity impede mainstreaming of climate adaptation into the energy sector. However, the formal knowledge base is still nascent?information needs are complex and to a certain extent regionally and sector specific. This report provides an up-to-date compendium of what is known about weather variability and projected climate trends and their impacts on energy service provision and demand. It discusses emerging practices and tools for managing these impacts and integrating climate considerations into planning processes and operational practices in an environment of uncertainty. It focuses on energy sector adaptation, rather than mitigation which is not discussed in this report. This report draws largely on available scientific and peer-reviewed literature in the public domain and takes the perspective of the developing world to the extent possible."
