Integrated force interaction simulation model for milling strategy optimization of thin-walled Blisk blade machining
(Elsevier B.V., 2021)
Complex shaped thin-walled blades that are extensively used in jet engines or stream turbines are very difficult to machine due to low rigidity of the blades, typically limited space between the blades and strict requirements ...
Effect of CNC Interpolator Parameter Settings on Toolpath Precision and Quality in Corner Neighborhoods
(Multidisciplinary Digital Publishing Institute (MDPI AG), 2022)
Surface quality, machining time, and precision of the final workpiece are key criteria of optimization in CNC machining. These criteria are influenced by multiple factors, such as path interpolation, feed drive system ...
Chatter‑free milling strategy of a slender Blisk blade via stock distribution optimization and continuous spindle speed change
(Springer, 2022)
The machining process of Blisk blades poses multiple challenges due to high requirements on surface quality and precision combined with high dynamic compliance of the thin-walled blades. Avoidance of chatter is thus of ...
In-Process Chatter Detection in Milling: Comparison of the Robustness of Selected Entropy Methods
(MDPI AG, 2022)
This article deals with the issue of online chatter detection during milling. The aim is to achieve a verification of the reliability and robustness of selected methods for the detection of chatter that can be evaluated ...
Strategy for Implementating Predictive Process-Oriented Machine Tool Digital Twins
(MM Science Journal, 2022)
Process planning for the productive machining of complex shaped parts is a comprehensive activity where the dynamic behaviour of a machine tool, workpiece and the process setting has to be taken into account. The predictive ...
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 ...
Experimental and theoretical study on the dynamic stiffness of circular oil hydrostatic shallow recess thrust bearings
(Elsevier, 2023)
The dynamic stiffness of traditional (deep recess) hydrostatic bearings decreases due to the fluid compressibility between the bearing and a compensation device, e.g., a capillary. Shallow recess bearings, on the other ...
