In the program, we will develop a measurement system based on the dynamics of the machining process. This system will use the variation in the forces or accelerations occurring during machining to characterize the mechanisms occurring between the cutter and workpiece. This will provide real time indications of the finish of the surface that is being created, the proximity to the chatter threshol ...

During the last two decades, software to support the manufacturing lifecycle has become pervasive. Sophisticated off the shelf packages are available for most standard manufacturing activities such as MRP, inventory control and dynamic scheduling. Unfortunately, most of this software has been developed in isolation by independent vendors and does not interoperate well with other independently de ...

The feasiblity of developing a PC based, pulsed ultrasonic test system for the economical and reliable testing of aluminum cylinders for sustained load cracking is addressed. A system consisting of a host PC, ultrasonic pulser/receiver and data acquisition hardware, control and analysis software, and transducer fixture for accurate positioning is proposed. In addition to the system development, ...

Recent catastrophic failures of Self Contained Underwater Breathing Apparatus (SCUBA) aluminum gas cylinders and similar air tanks have generated the need for a highly reliable, low cost inspection method to insure the integrity of these tanks. The failures of these tanks have been the result of crack formation in the neck and shoulder area. The cracks originate from the interior wall and can re ...

The storage photostimulable phosphor (SPP) technique has been demonstrated to be sensitive to ionization radiation. It is especially suited for detecting alpha particles since the efficiency is practically 100%. In addition to being able to quantify total ionization deposited in a SPP sensor, it also captures the radiation source distribution information in a digital image which can be readily ana ...

This proposal describes a new research program to be established at the small business Still Sciences, LLC, in collaboration with Department of Physics of Oklahoma State University. The overall goal is to develop and commercialize an all-optical dosimetry system for industrial radiation processing based on a novel Pulsed Optically Stimulated Luminescence readout technique and a new Al2O3 material ...

A diode laser method for the real-time measurement of absolute flux concentrations and spatial profiles of atomic beams used in MBE will be tested. The proposed method uses the doubled output of a near-infrared diode laser to access atomic absorption lines of species such as Ga, Al and In. The detection method will combine high frequency wavelength modulation and noise canceler approaches in order ...

Commercial aviation offers a low cost platform from which to make extensive humidity measurements, provided the instrumentation can run autonomously and endure the rigorous flight schedules. Advances in state of the art diode laser gas sensing technology make possible compact, fully automated, self-calibrating instrumentation with the sensitivity needed to measure humidity levels throughout the tr ...
