High-pressure flank cooling and chip morphology in turning Alloy 718
(Elsevier B.V., 2021)
The use of cutting fluids is commonly considered a necessity while machining Heat Resistant Super Alloys (HRSA). Specifically, cutting fluids applied under high-pressure, which for many decades have been the solution for ...
An Experimental Investigation of Controlled Changes in Wettability of Laser-Treated Surfaces after Various Post Treatment Methods
(MDPI, 2021)
In this paper, a quick nanosecond laser micro structuring process was employed to change the surface wettability of Ti6Al4V alloy. The same laser structuring method was used throughout, but with varying input fluence. The ...
Cutting temperature measurement in turning of thermoplastic composites using a tool-work thermocouple
(Springer, 2021)
Turning of carbon fibre reinforced thermoplastic pipes is used for production of fluid ducts for the aerospace and oil industries. Although thermoplastics are chemically stable, the matrix could be affected by the heat ...
A Comprehensive Methodology for Testing Hard Layers of Cutting Tool Properties in Orthogonal Turning
(MM Science Journal, 2022)
Thin hard layers deposited on cutting tools known as 'coatings' serve as a protective barrier against abrasion and adhesion wear, while also protecting against thermal and chemical processes that deteriorate the cutting ...
Experimental investigation of CMT discontinuous wire arc additive manufacturing of Inconel 625
(Springer, 2022)
Additive manufacturing (AM) is a progressive technology which holds promise for manufacturing of heat resistant super alloys. One of the most productive methods is wire arc additive manufacturing (WAAM). In this article, ...
Turning of titanium alloy with PCD tool and high-pressure cooling
(Elsevier, 2022)
Titanium alloys are difficult to cut materials due to their low thermal conductivity, which leads to intensive tool wear. The general issue is finding the best combination of cutting tool material and cutting conditions ...
Segmental Laser Stripping of Thin Coatings on Monolithic Cutting Tools
(MM Science Journal, 2022)
This study outlines the methodology of the new approach of laser stripping technique in functional surfaces of monolithic cutting tools. Starting from the initialization test of the coating thickness using a laser calotest ...
Cutting Force Modelling in Orthogonal Turning of C/PEEK and C/PA12
(MM Science Journal, 2022)
This article focuses on cutting force modelling in the orthogonal turning of two commonly used types of fibre-reinforced plastic materials. Uncoated cutting tool inserts made of sintered carbide and with different rake ...
An analytical formulation of ZOA-based machining stability for complex tool geometries: application to 5-axis ball-end milling
(Springer, 2022)
The paper describes a computationally convenient analytical formulation of the stability of the cutting process with respect to self-excited vibrations in the case of five-axis milling based on the commonly used zero-order ...
Automated feed rate optimization with consideration of angular velocity according to workpiece shape
(Elsevier B.V., 2022)
Selecting the proper cutting conditions for milling parts is one of the most important tasks in setting up manufacturing to achieve minimum machining times and to ensure the desired tool life. This is particularly important ...
