Starch

Starch

Wheat bran fiber, as the main byproduct of flour milling, is used as filling agent for maize starch based films. The properties of biocomposite films are studied. The results show that the addition of wheat bran fiber improves the mechanical properties of starch‐based films, which may meet the requirements of the food packing films.

Robust Chatter Stability Prediction of the Milling …

Milling stability is a function of the tool point frequency response functions (FRFs), which vary with the movements of the moving parts within the whole machine tool work volume. The position-dependent tool point FRFs result in uncertain prediction of the stability lobe diagram (SLD) for chatter-free machining parameter selection. Taking the variations of modal parameters to represent the ...

Regenerative chatter is a self-excited vibration that can occur during milling, which shortens the lifetime of the tool and results in unacceptable surface quality. In this paper, an improved semidiscretization method for modeling and simulation with variable pitch and variable helix milling is proposed. Because the delay between each flute varies along the axial depth of the tool in milling ...
