Cryogenic Mechanical Alloying of Poly (ether ether ketone) - Polycarbonate Composite Powders for Selective Laser Sintering [PDF]

open access: yes, 1999
Mechanical alloying is a solid state processing technique traditionally used in the metallurgical industry to extend solubility limits in alloy systems. Mechanical alloying can also be used to blend polymer systems at ambient or cryogenic temperatures.

A hybrid analytical and discrete based methodology to calculate path scallop of helical toroidal cutter in five-axis milling [PDF]

open access: yesFME Transactions, 2018
This paper presents a new method to calculate path scallop height of toroidal cutter during free-form surface machining in five-axis milling. The scallop height was defined as the distance between the tool intersection point and the normal point on the ...
