Mechanical Analysis of a Scraping Method to Remove Attached Barnacles

open access: yesJournal of Marine Science and Engineering, 2020
In order to clean the marine fouling attached to marine steel piles, a scraping method is proposed in this paper. Barnacles were used to represent a typical object needing removal, in order to estimate the maximum force required in the equipment designed

Experiments in the Machining of Ice at Negative Rake Angles

open access: yesJournal of Glaciology, 1984
AbstractThe cutting force components and the cutting moment on the cutting tool were measured during the orthogonal machining of ice with cutting tools inclined at negative rake angles. The variables included the cutting depth (< 1 mm), the cutting speed (0.01 ms−1 to 1 ms−1), and the rake angles (–15° to –60°).

Rake angle effect in cutting-based single atomic layer removal [PDF]

open access: yes, 2020
When minimum cutting depth is down to a single atomic layer, two portions of the cutting tool, namely, cutting edge and lowest atoms of the cutting tool, are involved in the cutting-induced material removal.

JUSTIFICATION OF RAKE ANGLE PARAMETERS REGARDING MOVEMENT AND RAKING OF HAY WITH ROTARY RAKES

open access: yesVibrations in engineering and technology
In modern conditions of agricultural production, improving the efficiency of hay harvesting technologies is an important task for ensuring quality fodder for livestock. One of the key elements in this process is the use of rotary rakes to move and rake the hay. The efficiency of these machines largely depends on the design parameters, in particular the
