Among the biocompatible materials, Ti6Al4V titanium alloy is widely spread due to its properties, such as corrosion and fatigue resistance combined with low density. can be processed by Additive Manufacturing technologies, Power Bed Fusion (PBF). The biomedical applications require good surface finishing ensure biocompatibility tissues organs. Machining an adequate process final roughness of co...

Abstract Nanomaterials such as graphene have been added to various matrices enhance mechanical, thermal and electrical properties for applications requiring intricate designs at the micro-scale. At this scale, mechanical micro-machining is utilised post-processing achieve high surface quality dimensional accuracy while still maintaining productivity. Therefore, in study, machinability of polyme...

L aboratory milling systems are used throughout the rice industry to 1) estimate the milling yield that may be expected of rice lots when milled in large-scale milling systems and 2) produce milled rice samples from which visual, functional, sensory and nutritional assessments of the rice lot can be made. This chapter presents factors that can affect the laboratory measurement of rice milling ...

Abstract Nanofluid minimum quantity lubrication (NMQL) is a green processing technology. Cottonseed oil suitable as base because of excellent performance, low freezing temperature, and high yield. Al 2 O 3 nanoparticles improve not only the heat transfer capacity but also performance. The physical chemical properties nanofluid change when are added. However, effects concentration on performance...

This work presents a PCD (polycrystalline diamond) end mill with a new staggered structure for the milling of CFRP (carbon fiber reinforced plastic). The magnitude and direction of cutting force is decreased and changed by side-edge re-configuration of the structure. The flute and insert pocket of the staggered PCD end mill are designed considering the tool’s stiffness and welding process. The ...

In the fabrication process of thin-walled micro-parts, both micro-cutting tools and micro-parts have characteristics small size low stiffness. Therefore, regenerative chatter during machining cannot be ignored. The influence tool runout error actual trochoidal trajectories cutting edge on micro-milling forces should also considered comprehensively. this paper, in is first analysed, an instantan...

: [email protected] .ac.cn (W. Han). Abstract The unique micro-sized (2–10 mm) Si/C composites consisting of 20 nm carbon coated secondary Si were synthesized from the abundant and low cost Al–Si alloy ingot by acid etching, ball-milling and carbonization procedure. The nano-porous Si/C composites provide a capacity of 1182 mAh g 1 at a current density of 50 mAg , 952 mAh g 1 at 200 mAg , 815 mAh g...
