Tool Orientation Planning in Milling With Process Dynamic Constraints: A Minimax Optimization Approach
(The American Society of Mechanical Engineers (ASME), 2018)In five-axis milling process, the tool path generated by a commercial software seldom takes the dynamics of the machining process into account. The neglect of process dynamics may lead to milling chatter, which causes ... -
An Analytical C3 Continuous Local Corner Smoothing Algorithm for Four-Axis Computer Numerical Control Machine Tools
(The American Society of Mechanical Engineers (ASME), 2018)Linear motion commands of multi-axis computer numerical control (CNC) machine tools need to be smoothed at the transition corners, because the velocity discontinuities at corners can result in fluctuations on machine tool ... -
Robust Active Chatter Control in Milling Processes With Variable Pitch Cutters
(The American Society of Mechanical Engineers (ASME), 2018)Milling chatters caused by the regenerative effect is one of the major limitations in increasing the machining efficiency and accuracy of milling operations. This paper studies robust active chatter control for milling ... -
Spiral Curve-Based Efficient Five-Axis Sweep Scanning of Barrel-Shaped Surfaces
(The American Society of Mechanical Engineers (ASME), 2018)Barrel-shaped surfaces are widely used in industries, e.g., blades, vases, and tabular parts. Because a part such as an aero-engine blade is typically quite large, the efficiency of its measurement becomes a critical issue. ... -

Novel Friction-Assisted Tube Forming Methods: A Comparison of Microstructure and Mechanical Properties
(The American Society of Mechanical Engineers (ASME), 2018)Expanding performance of friction power in material processing techniques, considerably improves the process efficiency while decreases required load and increases imposed strain by the localized material softening. This ... -
A Graphics Processor Unit-Accelerated Freeform Surface Offsetting Method for High-Resolution Subtractive Three-Dimensional Printing (Machining)
(The American Society of Mechanical Engineers (ASME), 2018)Machining is one of the major manufacturing methods having very wide applications in industries. Unlike layer-by-layer additive three-dimensional (3D) printing technology, the lack of an easy and intuitive programmability ... -
Milling Bifurcations: A Review of Literature and Experiment
(The American Society of Mechanical Engineers (ASME), 2018)This review paper presents a comprehensive analysis of period-n (i.e., motion that repeats every n tooth periods) bifurcations in milling. Although period-n bifurcations in milling were only first reported experimentally ... -
