This project describes research that will lead to the commercialization of the Tool Dashboard, a new technique for pre-process milling parameter selection. In this approach, dynamic models of the cutting tool and holder will be analytically coupled to spindle-machine measurements to predict the tool point dynamics. Given this information, stability lobe diagrams, which display stable and unstable ...

We propose a Phase II joint experimental and computational program to predict the behavior of heterogeneous energetic materials. Specifically the system will predict the properties and dynamics of their initiation during slow and fast cookoff experiments in fully-instrumented tests cells, allowing for spatial and temporal resolution of critical dynamic variables. The modeling and simulation effort ...

Existing machine tool metrology methods measure the quasistatic errors of a machine tool and, thus, evaluate its static positioning accuracy. Yet machine tools are dynamic, they do not stop and pause in an effort to reach a programmed position. Additionally, current techniques do not identify all of the errors, many of which significantly impact the volumetric accuracy of the machine. Almost immed ...

QuesTek Innovations LLC proposes to expand its computational Materials by Design® technology by developing a “design toolkit” that enables the computational design and development of oxidation- and creep-resistant ductile multicomponent Molybdenum-based superalloys for use at 1300C and above. The proposed toolkit will build upon key mechanistic insights gained in the Phase I program and en ...

The proposed project will undertake the research, design, and development of key concepts and technologies for extended duration optical arbitrary waveform generator (OAWG) over large bandwidth, based on a monolithically integrated high-speed optoelectronic chip with a unique integrated ultimate-resolution super-compact grating (URSCG). The proposed OAWG is capable of continuously extendable dura ...

New forms of data visualization require new ways of thinking about data, how we work with it and what we expect from it. A fundamental dissonance exists between computer memory and human experience. This becomes especially apparent when human, social, cultural and behavioral data are being consulted to help find the optimum course of action. Our approach to data is based upon Bloom, a core server ...

Under this SBIR program, QuesTek proposes to develop novel thermo-mechanical processing techniques to enhance the bending and contact fatigue resistance of high strength secondary hardening matensitic steels such as Ferrium® C64 for rotorcraft drive train components. A systems-engineering approach will be followed to identify key microstructure attributes (e.g., nonmetallic inclusions) controll ...

We will use our newly developed smart energetic materials to eliminate flame sensitive pyrogens and the bridge-wire connections for thermal ignition within initiators/squibs which will improve safety for Mil. Std. 1901A compliance. Unlike conventional materials, new pyrogen materials are insensitive to ignition by flame and so can not flame spread by impingement. However, new faster burning formu ...

We propose to enhance and commercialize software tools for imaging and three-dimensional reconstruction of as-produced propellant grains from micro-tomographic volume-imaging techniques; computational tools that model the morphology of the propellant grain, including first-, second-, and third-order statistics; and computational tools that determine local material properties, including elastic mod ...

Cathodic protection methods, employing a sacrificial anode, are used to prevent corrosion of iron-based structural components in marine environments. However, as a consequence of galvanic coupling, hydrogen charging of high-strength steels occurs leading to hydrogen embrittlement and stress-corrosion cracking (SCC). Under this proposed SBIR program, QuesTek Innovations LLC, a leader in the field o ...
