An optimization dust-removing electrode design method aiming at improving dust mitigation efficiency in lunar exploration

This work presents an experimental work in orbiting EDM which design of the electrode used adopt the non-uniform offset method formulated by the authors. A brief explanation about the design principle is presented in this paper as well as comparison of experimental machining results between uniform tool offset and the said method. The design method is implemented in a commercial CAD software and the system has been proven effective to cut design lead time and reduce error. The experimental part on orbiting EDM adopting the said-method yields improved machining accuracy and machined surface quality.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.
