Improved Use of the Full Length of Milling-Tool Flutes in Processes of Air-Contour Milling

open access: yesJournal of Manufacturing and Materials Processing
The cutting length of milling tools must be longer than the axial distance of the material to be processed. In fact, in most cases, the cutting length far exceeds the thickness of the material to be removed.

Surface texture produced by peripheral milling with helical end mills

open access: yes
An investigation of the surface texture produced by peripheral milling with end mills has been made. Theoretical relationships are presented to predict the theoretical cusp height and approximate the arithmetical average surface roughness based on the geometrical considerations of a circular tooth path.

Analytical Cutting Forces Model Of Helical Milling Operations

open access: yes, 2011
Helical milling operations are used to generate or enlarge boreholes by means of a milling tool. The bore diameter can be adjusted through the diameter of the helical path. The kinematics of helical milling on a three axis machine tool is analysed firstly.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

open access: yesChemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...

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 ...
