Influence of V concentration in TiAlSiVN coating on self-lubrication, friction and tool wear during two-pass dry turning of austenitic steel 316 L
(Elsevier, 2024-05)
The present work investigates the performance of TiAlSiVN coating with 5 and 11 at% of V concentration deposited on the Al2O3/SiC cutting tools during dry turning of austenitic 316 L stainless steel. The maximum flank wear ...
Stiffening near-net-shape functional parts of Inconel 718 LPBF considering material anisotropy and subsequent machining issues
(Elsevier, 2021-12-24)
[EN] Additive manufacturing of metallic parts has witnessed significant development. The laser powder bed fusion (LPBF) process has emerged as a key process for manufacturing thin-walled components. However, despite the ...
In-Process Machining Distortion Prediction Method Based on Bulk Residual Stresses Estimation from Reduced Layer Removal
(MDPI, 2024-01-03)
Manufacturing structural monolithic components for the aerospace market often involves machining distortion, which entails high costs and material and energy waste in industry. Despite the development of distortion calculation ...
Fatigue Life Estimation Model of Repaired Components with the Expanded Stop-Hole Technique
(MDPI, 2024-02-01)
Fatigue crack growth tests are conducted to assess the efficacy of the stop-hole crack repair method. This straightforward and widely adopted technique involves drilling a hole at the crack tip and subsequently enlarging ...
On the relationship between cutting forces and anisotropy features in the milling of LPBF Inconel 718 for near net shape parts
(Elsevier, 2021-11)
The versatility and potential applications of additive manufacturing have accelerated the development of additive/subtractive hybrid manufacturing methods. LPBF processes are exceptionally efficient at producing complex-shaped, ...
Drilling of CFRP-Ti6Al4V stacks using CO2-cryogenic cooling
(Elsevier, 2021-04)
In the work here presented, liquefied CO2 is used as cutting fluid for drilling CFRP-Ti6Al4V stacks as alternative to dry-drilling. Several tests were performed using dry-drilling technique, to compare this with the ...
