Prospects of improving control over the process of electrochemical machining of the blade airfoil profile using the duplex mode method

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2023
The paper discusses the features of machining of a compressor blade airfoil. The problem of airfoil deformations under the action of residual stresses that negatively affect the accuracy of the relative position of the airfoil relative to the blade root ...

Prediction of machining accuracy degradation of machine tools

Precision Engineering, 2012
Abstract Machine tool has to maintain its accuracy for quality control of products. After a long period of cutting operations, obvious wear will occur on the contact surfaces of the slide and the guideway. Such a wear will degrade the accuracy of machine tool due to the increase of Abbe errors.

Influence of Tool Length and Profile Errors on the Inaccuracy of Cubic-Machining Test Results

Journal of Manufacturing and Materials Processing, 2021
A cubic-machining test has been proposed to evaluate the geometric errors of rotary axes in five-axis machine tools using a 3 × 3 zone area in the same plane with different tool postures. However, as only the height deviation among the machining zones is

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
