2013-9-19 Unequal helix angles lead to varying tooth pitches. Thus, the cutting condition of each tooth is different. A mechanistic model is presented to determine incremental process forces along the tool axis. Based on the proposed model, stability charts for tools with unequal helix angles are computed and compared with experimental investigations ...

Read MoreThe stability of cutting processes in end milling can be increased by an optimization of the tool geometry. In this paper the influence of unequal helix angles is investigated. Unequal helix angles lead to varying tooth pitches. Thus, the cutting condition of each tooth is different. A mechanistic model is presented to determine incremental process forces along the tool axis.

2020-7-26 Chatter is one of the significant limitations in the milling process, which may cause poor surface quality, reduced productivity, and accelerated tool wear. Variable pitch and variable helix tools can be used to suppress regenerative chatter. This study extends the high-order full-discretization methods (FDMs) to predict the stability of milling with variable pitch and variable helix tools.

2015-5-15 An in vitro selection method for ligand-responsive RNA sensors was developed that exploited strand displacement reactions. The RNA library was based on the thiamine pyrophosphate (TPP) riboswitch, and RNA sequences capable of hybridizing to a target duplex DNA in a TPP regulated manner were identified. After three rounds of selection, RNA molecules that mediated a strand exchange

2021-3-11 Dendrite formation on Li metal anodes hinders commercialization of more energy-dense rechargeable batteries. Here, we use the migration energy barrier (MEB) for surface transport as a descriptor for dendrite nucleation and compare Li to Mg. Density functional theory calculations show that the MEB for the hexagonal close-packed structure is 40 and 270 meV lower than that of the body
