RISA Legendre Polynomials Based Method for Stability Analysis of Milling Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a timedomain approach for a semianalytical prediction of stability in milling using the Legendre polynomials. The governing equation of motion of milling processes is expressed as a delaydifferential ...
Hybrid Digital Image Correlation–Finite Element Modeling Approach for Modeling of Orthogonal Cutting Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cutting process modeling is still a significant challenge due to the severe plastic deformation of the workpiece and intense friction between the workpiece and tool. Nowadays, a novel experimental approach based on digital ...
Effects of Process Parameters on White Layer Formation and Morphology in Hard Turning of AISI52100 Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hard turning is becoming increasingly considered by industry as a potential substitute for grinding. However, it is greatly hurdled by surface integrity problems such as tensile residual stress and white layer, which are ...
Harmonic Differential Quadrature Method for Surface Location Error Prediction and Machining Parameter Optimization in Milling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a semianalytical numerical method for surface location error (SLE) prediction in milling processes, governed by a timeperiodic delaydifferential equation (DDE) in statespace form. The time period is ...
On the Steady-State Workpiece Flow Mechanism and Force Prediction Considering Piled-Up Effect and Dead Metal Zone Formation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The manufacturing of miniaturized components is indispensable in modern industries, where the uncut chip thickness (UCT) inevitably falls into a comparable magnitude with the tool edge radius. Under such circumstances, the ...
