End mill tools integration in CNC machining for rapid manufacturing processes: simulation studies

Production and Manufacturing Research: An Open Access Journal, 2015
Computer numerical controlled (CNC) machining has been recognized as a manufacturing process that is capable of producing metal parts with high precision and reliable quality, whereas many additive manufacturing methods are less capable in these respects.

Chemical and spectroscopic analysis of olive mill waste water during a biological treatment [PDF]

, 2007
The treatment of olive mill waste water was studied on the laboratory scale. Physico–chemical analyses showed the final products had a mean pH of 5.4 without neutralisation and 5.7 when lime was added to the process.

A Vascular Microphysiological Model of Lung Fibrosis Reveals That Myofibroblasts and IPF Patient‐Derived Fibroblasts Impair Angiogenesis and Vasculogenesis

Advanced Functional Materials, EarlyView.
A microphysiological lung fibrosis model recapitulates myofibroblast–vascular interactions. Induced myofibroblasts and patient‐derived IPF fibroblasts impair angiogenesis and increase vascular permeability via TGF‐β1–driven signaling. Pharmacological interventions with SB 431542 and VEGF supplementation restore vascular morphology and barrier function.

Dundee’s Jute mills and factories: Spaces of production, surveillance and discipline [PDF]

, 2005
Taking Dundee’s jute industry as its focus, this paper provides a geographical reading of the architectural form, design and layout of the mills and factories of the late nineteenth century. By tracking the change from the multi-storey to the shed system,

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

Advanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

Feature recognition & tool path generation for 5 axis STEP-NC machining of free form / irregular contoured surfaces [PDF]

, 2010
This research paper presents a five step algorithm to generate tool paths for machining Free form / Irregular Contoured Surface(s) (FICS) by adopting STEP-NC (AP-238) format. In the first step, a parametrized CAD model with FICS is created or imported in

Burrs produced by end milling [PDF]

, 1976
The operation of small precision mechanisms such as timers, switches, or actuators depends on burr-free, sharp-edged component parts. Traditional methods of producing these near-perfect edges on miniature parts are costly and not as precise or repeatable as some piecepart designs require.

Multiscale Structuring of Hydroxyapatite via Two‐Photon Lithography of Nanocomposites

Advanced Functional Materials, EarlyView.
Hydroxyapatite scaffolds are of great interest in bone tissue engineering applications, ranging from 3D cell culture to regenerative medicine. Using two‐photon lithography of a transparent nanocomposite, hydroxyapatite microstructures with features ranging from submicron to centimeter‐scale are fabricated. This allows to mimic the natural bone geometry,
