An analytical formulation of ZOA-based machining stability for complex tool geometries: application to 5-axis ball-end milling
Autor: Falta J.; Sulitka M.; Zeman P.
(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 ... -
Calibration Method for In-Process Identification of Tangential Specific Cutting Force in Milling
Autor: Janota M.; Kolář P.; Falta J.; Kozlok T.
(MDPI AG, 2022)The cutting forces that occur during machining cause static and dynamic deformations of the machine–tool–workpiece system. In general, the cutting force is spatial. However, knowledge of the tangential component of the ... -
Chatter suppression in finish turning of thin-walled cylinder: model of tool workpiece interaction and effect of spindle speed variation
Autor: Falta J.; Janota M.; Sulitka M.
(Elsevier B.V., 2018)Finishing operation of a thin-walled cylindrical workpiece may suffer from regenerative vibration due to high compliance of the workpiece and tool-workpiece interaction on a tool nose. In this case the machining stability ... -
Chatter‑free milling strategy of a slender Blisk blade via stock distribution optimization and continuous spindle speed change
Autor: Petráček P.; Falta J.; Stejskal M.; Šimůnek A.; Kupka P.; Sulitka M.
(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 ... -

Identifying the lead angle limit to achieve required surface roughness in ball-end milling
Autor: Pešice M.; Vavruška P.; Falta J.; Zeman P.; Malý J.
(Springer, 2022)When milling generally shaped surfaces with a ball-end milling tool, machined surface roughness and accuracy as well as machining productivity are often monitored. Improving one of these parameters often causes a decrease ... -
In-Process Chatter Detection in Milling: Comparison of the Robustness of Selected Entropy Methods
Autor: Hauptfleischová B.; Novotný L.; Falta J.; Machálka M.; Sulitka M.
(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 ... -
Integrated force interaction simulation model for milling strategy optimization of thin-walled Blisk blade machining
Autor: Sulitka M.; Falta J.; Stejskal M.; Hauptfleischová B.
(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 ... -
Machining of thin blade using vibration prediction and continuous spindle speed control
Autor: Vavruška P.; Sulitka M.; Stejskal M.; Šimůnek A.; Falta J.; Heinrich P.; Kopal M.
(MM Science Journal, 2019)The paper focuses on the issue of controlling the cutting conditions in finishing machining of compliant workpieces, such as typically thin blades, in order to eliminate undesirable vibration and achieve high quality ...
