Linear analysis of chatter vibration and stability for orthogonal cutting in turning
(2011)
The productivity of high speed milling operations is limited by the onset of self-excited vibrations known as chatter. Unless avoided, chatter vibrations may cause large dynamic loads damaging the machine spindle, cutting ...
Experimental and numerical study on the thermoforming process of amorphous thermoplastic polymers
(Carl Hanser Verlag, 2019)
Thickness distribution has an important impact on the quality of thermoformed products. It has significant effects not only on durability but also on the oxygen and gas transmission rate of thermoformed packaging products. ...
Decomposition of Process Damping Ratios and Verification of Process Damping Model for Chatter Vibration
(2012)
In the previous study, by the same authors, titled ‘‘A new process damping model (PDM) for chatter vibration (Measurement, 44 (8) (2011) 1342–1348)’’, a new approach has been presented for obtaining process damping ratios ...
A simple approach to analyze process damping in chatter vibration
(2014)
This paper investigates how changes in chatter amplitude and frequency depend on process damping effect in dynamic turning process. For this purpose, the two degrees of freedom (TDOF) cutting system was modeled, and for ...
Optimization of tool geometry parameters for turning operations based on the response surface methodology
(2011)
This investigation focuses on the influence of tool geometry on the surface finish obtained in turning of AISI 1040 steel. In order to find out the effect of tool geometry parameters on the surface roughness during ...
Experimental Investigation for Alternative Use of Agricultural and Domestic Wastes
(2018-06)
Along with the reduction of fossil fuels, various studies are being carried out on the availability of alternative energy sources. Within the scope of this study, we can evaluate as agricultural and domestic waste; hazelnut ...
AN EXPERIMENTAL STUDY ON WALL THICKNESS DISTRIBUTION IN THERMOFORMING
(Lublin Univ Technology, Poland, 2017)
In this work, Polystyrene (PS) sheets were thermoformed in predetermined conditions. Wall thickness distributions obtained by experimental method in PS thermoformed products. Then the same thickness distributions were ...
A new process damping model for chatter vibration
(2011)
This paper presents a new analytical process damping model (PDM) and calculation of Process Damping Ratios (PDR) for chatter vibration for low cutting speeds in turning operations. In this study a two degree of freedom ...
Drying of Prina Using Microwave Energy and Determination of Appropriate Thin Layer Drying Model
(Univ Namik Kemal, 2015)
This study examined the thin layer drying kinetics of the prina in the microwave. Prina samples with 7mm, 9mm and 11mm thickness were dried using 90, 180, 360 and 600 W (2450 MHz) microwave output powers and changing of ...
Modelling of dynamic cutting force coefficients and chatter stability dependent on shear angle oscillation
(Springer London Ltd, 2017)
Productivity of high-speed turning operations is limited by the onset of self-excited vibrations known as chatter. Unless avoided, chatter vibrations may cause large dynamic loads damaging the machine spindle, cutting tool ...
