On the Determination of Milling Cutter Contour of Screwed Surface.
Journal of the Society of Mechanical Engineers, 1937 各種螺旋面例へば、ねぢ、捩錐の溝等をフライス仕上なす場合、最も重要なことは刄形の決定である。旋盤で仕上る場合の様に簡單に求められないのは勿論で、そのために種々の方法が考案されたが、工具の大きさ、工具軸の傾け角等の影響を一目に知るには是非觧析的な觧法を要する。筆者はここに一つの図示的觧法を基礎にして、新しい觧析的觧法を求めた。先づ一般の場合に就て述べ、次いで二三の特殊な例に及ぼす。

Advanced Functional Materials, EarlyView.This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

TOOL WEAR MEASUREMENT AFTER MILLING OF ALUMINUM ALLOY USING COMBINED ROUGHNESS AND CONTOUR DEVICE [PDF]
Applied Computer Science, 2015 During separation of work surface in machining process and transforming it into chips, tool remains in constant contact with the workpiece. During this contact, there are a series of phenomena leading to the tool wear.

In Vitro Flow Modelling for Mitral Valve Leakage Quantification [PDF]
, 2009 In this study particle image velocimetry (PIV) is used to measure and visualise the blood flow through a leaking mitral heart valve. The results are compared with the results from Doppler echocardiography and computational fluid dynamics (CFD). Using CAD,

Design and milling manufacture of polyurethane custom contoured cushions for wheelchair users
Australasian Medical Journal, 2011 The design of custom contoured cushions manufactured in flexible polyurethane foams is an option to improve positioning and comfort for people with disabilities that spend most of the day seated in the same position. These surfaces increase the contact area between the seat and the user.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Contour parallel milling tool path generation for arbitrary pocket shape using a fast marching method [PDF]
, 2018 Contour parallel tool paths are among the most widely used tool paths for planer milling operations. A number of exact as well as approximate methods are available for offsetting a closed boundary in order to generate a contour parallel tool path ...

Influence of Curved Workpiece Contours on Delamination During end Milling of FRP
Procedia CIRP, 2017 When end milling long fiber reinforced composites, fiber protrusions of the top layers can occur. The lengths of fiber protrusions found on real workpieces with curved contours cannot be explained so far. The lengths of individual fibers to be cut along the tool path depend on tool diameter, local fiber orientation and path geometry.
