During the transferring process of the large die surfaces, there are extensive needs of die surface polishing. Since almost large die surfaces are free-form surfaces, currently, these are almost manually implemented. In order to overcome this barrier, base on design a floating polisher, this paper focuses on polishing rule of floating three polishing disks and the optimization of the associated polishing process parameters. In order to enhance the polisher performance, affecting factors of polishing process, including the rotation speed of polishing discs, normal acting force on polishing disc, loci of polishing disc movement, feeding rate of polishing disc, grit of abrasive particles, and inclined angle of the acting force on disc, are synchronized and analyzed versus roughness of polished surfaces. Then, using the parameter design plans and conducts tests regarding these affecting factors. Finally, the floating polishing process parameters are optimized based on the test results. These optimized results are used as operating guides for applications of the floating die polisher.

This paper represents a dual-plane polishing method for ceramics ball. Compared with traditional ball polishing method, its upper and lower plate are all flat and easy to use soft pad to polish, so it can largely reduce the surface mechanical damage and obtain high quality processing surface. This paper analyzes surface polishing trajectory by calculation and simulation to test the polishing trajectory uniformity. A mathematics model of polishing process is established to disintegrate the process of a balls movement. Experiment is operated in dual-plane planetary polishing machine. The result shows that perfect polishing surface and spherical error can be obtained under the proper process parameters, the surface roughness achieves 4nm and the spherical error can reach 0.217μm.

Free Form Surfaces

Eine steigende Nachfrage an komplex geformten Bauteilen fordert neue, produktivere Fertigungsverfahren sowohl für die Luftfahrt wie auch für die Medizintechnik. Die Bahnplanung für diese Bauteile kann durch die gezielte Verwendung von Bearbeitungswinkeln verbessert werden. Bisher ist der Einfluss sich ändernder Winkel während der Bearbeitung auf die Oberflächenqualität des Bauteils jedoch unzureichend untersucht. Dieser Artikel zeigt vorteilhafte Winkelbereiche für zwei beispielhafte Maschinen und Werkzeuge auf.   An increasing demand for complex shaped parts requires new methods for increasing the productivity in machining of those parts. The path planning for free form grinding can be improved by fitting the surface curvature of the workpiece to the shape of engagement of the tool. So far, there has been little investigation concerning the effects of the yaw angle on the surface quality. This paper shows beneficial yaw angles for a set of process parameters on two different machines and tools.
