Parametric evaluation and predictive modelling of formability in μ-SPIF process [PDF]

MATEC Web of Conferences
Single Point Micro Incremental Forming (µ-SPIF) is a versatile route for complicated, and customized micro-components. Localised deformation in terms of bending stretching and through thickness shears add the complexity in SPIF which intensifies in case ...

Study of the Effect of Process Parameters on Surface Profile Accuracy in Single‐Point Incremental Sheet Forming of AA1050‐H14 Aluminum Alloy

Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020
Single‐point incremental forming is an innovative flexible and inexpensive technique to form sheet products when prototypes or small batches are required. The process allows complex geometries to be produced using a computer numerical control machine, eliminating the need for a special die.

Randomized, Double‐Blind, Placebo‐Controlled, Single Ascending Dose Trial of Synthetic Preimplantation Factor in Autoimmune Hepatitis

Hepatology Communications, 2018
Preimplantation factor (PIF) is an evolutionary conserved peptide secreted by viable embryos which promotes maternal tolerance without immune suppression. Synthetic PIF (sPIF) replicates native peptide activity.

Spif on Polymers – Experimental Data Design and Processing

Acta Universitatis Cibiniensis. Technical Series, 2023
Abstract The paper’s aim is to describe the stages of the experimental research as well as the processing of data measured in the SPIF of some polymeric materials using methods such as the Taguchi method, ANOVA analysis, and establishing the regression equation to determine the relevant factors of influence.
