Statistical investigation of modal parameters of cutting tools in dry turning

Influence of machining parameters on fatigue endurance limit of AISI 4140 steel

“…It can be observed that the greatest changing of average surface roughness parameters (R a and R q ) is caused by the feed rate, when compared with cutting speed and depth of cut. This is also in accordance with some previous published papers (Abouelatta andMádl, 2001 andThomas et al, 2003). The change of maximum height roughness parameter (R t ) is similar for all conditions.…”

“…For the majority of these authors, the feed rate is the main influencing cutting parameter on surface roughness of steels. Besides, the vibratory response of a machine tool system is also important in the development of the surface roughness (Benardos and Vosniakos, 2003, Thomas and Beauchamp, 2003and Jang and Seireg, 1989.A comprehensive review of published data, which addresses the effect of machining and surface integrity on fatigue life has been made by Novovic et al (2004). According to these authors, there is some disagreement in the literature about the influence of surface roughness on fatigue life.…”

A review of chatter vibration research in turning

“…Impact testing is the most conventional experimental method for obtaining dynamic parameters for the chatter model. In particular, the natural frequency, damping ratio, Real and Imaginary parts of the transfer function are determined by impact testing technique which has been used by several researchers [10,[22][23][24][25][26][27][28]. The structural stiffness (k) of the tool-workpiece system can be obtained by simultaneous measurement of displacement and static force applied at the end of the workpiece through the tool as shown in [10,24,28].…”

A Drives and Control Integrated Time-Domain Dynamic Analysis and Modeling Approach Applied To Ultra-Precision Machine Tools

“…But to microstructure surfaces machining, every direction of the environment vibration produce important influence, therefore, the simulation system will be imposed environmental interferer on the X, Y and Z direction respectively. Environmental interferer is expressed by (Luo et al, 2005;Thomas and Beauchamp, 2003): ( )…”
