... toolpath with a set of short line segments is the most commonly used numerical control (NC) code format in high-speed machining (HSM) [ 1 ]. Considering the drive constraints of the machine tools, tangential and curvature discontinuities exist at sharp corners, which result in machining feedrate...

...Binbin Xu; Jun Zhang; Hongguang Liu; Xiang Xu; Wanhua Zhao Difficult-to-cut materials are widely used in aerospace and other industries. Titanium alloys are the most popular ones among them due to their high strength-to-weight ratio and high temperature resistance. However, in high-speed machining...

...Jun Zhang; Xiang Xu; José Outeiro; Hongguang Liu; Wanhua Zhao During high-speed machining (HSM), the microstructure of materials evolves with significant plastic deformation process under high strain rate and high temperature, which affects chip formation and material fracture mechanisms, as well...

...; published online June 5, 2014. Assoc. Editor: Donggang Yao. 16 05 2013 08 05 2014 This study focuses on addressing the severe plastic deformation (SPD) behavior and the effects of machining parameters on microstructure alternations in machined surface created from high-speed machining...

...Yiğit Karpat; Tuğrul Özel High-speed machining offers several advantages such as increased flexibility and productivity for discrete-part manufacturing. However, excessive heat generation and resulting high temperatures on the tool and workpiece surfaces in high-speed machining leads to a shorter...

...P. T. Mativenga, Lecturer; K. K. B. Hon, Professor The characteristics of high-speed machining (HSM) dynamic milling forces was investigated. Recent studies in chip segmentation are discussed. A Mikron 700 High-Speed Machining Center was used in the end-milling of AISI H13 tool steel using PVD TiN...

... by a desire to minimize acceleration requirements and maintain a stable steady-state cutting process during high-speed machining. The algorithm has been implemented for two-dimensional contiguous end-milling operations with flat end-mills, and case studies are presented to illustrate the approach. One...

...Tony L. Schmitz; G. Scott Duncan In this paper we present the second generation receptance coupling substructure analysis (RCSA) method, which is used to predict the tool point response for high-speed machining applications. This method divides the spindle-holder-tool assembly into three...
