Characterization and testing of a height adjustable kinematic coupling

[摘要] A new height adjustable kinematic coupling has been designed for a next generation high precision ceramics grinding machine designed to have total loop stiffness of 60 N/[mu]m. A test apparatus and prototype of the new coupling design has been built as the subject of this thesis to test the coupling in a model of the grinding machine layout to characterize coupling stiffness and range & precision of height adjustability. Here, the prototype coupling and test apparatus design, with initial results that verify the system;;s manufacturing are reported. Some design revisions to the coupling are also suggested. Future work will report coupling characterization and coupling-machine integration. Other future work will use this test setup to test and optimize control system design of the three- groove active kinematic coupling layout and finalize the component choice for the production grinding machine.
