A Study of Fineblanking for the Manufacture of Flueric Laminar Proportional Amplifiers.
Abstract
A nonconventional stamping process, known as fineblanking, is investigated for use in high-volume production of flueric laminar proportional amplifiers. The investigation includes the standard deviation of critical dimensions, supply and control flow measurements for a constant pressure, amplifier gain, common-mode rejection ratio (CMRR), and cost breakdown. The present study indicates that fineblanking yields a significant improvement over metal photochemical etching (a widely used fabrication technique) in the repeatability of geometric parameters. Typical standard deviations of a nozzle width are less than 0.5 percent. Further, a 61.3-percent improvement of the mean CMRR was observed. (Author)
