Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics
Advanced Engineering Materials, EarlyView.Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

Force and Temperature Modeling in 5 - axis Grinding
Procedia Manufacturing, 2018 Abstract Building upon a recently published (J. Manuf. Sci. Eng. 2017;. doi:10.1115/1.4037969) general geometrical framework for specific removal rate, the current paper develops the physics in 5 - axis grinding (5AG). Relating the grain-level chip thickness h to the wheel-local material removal rate per unit area m”, grinding force components from ...
