All machined surfaces inherently have roughness. The level of control of this surface is dependeat on the specifications outlined for its intended use. In strictly controlled situatiom, the monitoring and characterization of these surfaces becomes increasingly important to ensure that each component conforms to specifications. For this reason, the need f,)r in-situ monitoring systems has increased in order to optimize manufacturing time and minimize generated scrap for companies to remain competitive in industry. Current in-situ roughness monitoring systems, such as optical methods, are limited by the harsl: environments in which these systems are required to operate and the requirement for highly reflective materials. Accordingly, the need to develop a more robust system is required. The objective of this work was to develop and test a noncontact surface roughness characterization system which can be implemented into a machining center in order to provide in-situ measurements where currently available methods are rendered inappropriate.
Thiis essay explores Johann Wolfgang von Goethe*s reaction to Newtonian science and its quantification of nature. In particular, Goethe insisted that Newton's mechanistic portrayal of light and color was but a partial account of their reality. Broadening the understandings upon which science is practiced, Goethe developed ideas that presuppose mind-world intimacy and the consequent need to acknowledge the limited utility of mathematical modeling and theory construction. Such an approach values human subjectivity and sees it as partly constitutive of nature. While Goethe's treatment of color and light is not religious in a traditional sense, it resonates overtones consonant with religious belief. Rejecting the materialistic emphasis of Newtonian physics, Goethe felt that science may expand our spiritual horizons by helping us see the many ways we are patterned into the phenomenological splendor of the world This outlook aligns with Goethe's belief-illustrated in Faust-that the soul holds out for something more than a materialistic metaphysics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
