A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...

In this paper, the design and implementation of an effective neural network model for turning process identification as well as a neural network controller to track a desired vibration level of the turning machine is as an example of using the neural network for manufacturing process control. Multi – Layer Perceptron (MLP) neural network architecture with Levenberg Marquardt (LM) algorithm has ...

the use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. laser assisted machining (lam) improves the machinability of high strengt...

This paper presents the three dimensional (3D) finite element analysis to predict the workpiece displacement amplitude and tool wear in face turning of AISI 1040 steel under dry machining condition. 3D vibration induced turning models have been developed and validated by comparing with experimental results so as to identify the correlation. Extensive experimentation and investigators carried ou...

In the 2D-Vibration Assisted Cutting (2D-VAC) method, cutting tool shakes in a 2-dimensional approach because of superimposed high-frequency modulation. This modulation effect creates displacement at tiny scale micrometers and causes an escalation resultant speed. Consequently, 2D-VAC has superior advantages compared to traditional (TC). manuscript describes research on that focuses modeling fo...
