Abstract: Numerical and experimental analyses of milling bifurcations, or instabilities, are detailed. The time-delay equations of motions that describe milling behavior are solved numerically and once-per-tooth period sampling is ...

Abstract: 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 ...

Abstract: A new metric is presented to automatically establish the stability limit for time domain milling simulation signals. It is based on periodically sampled data. Because stable cuts exhibit forced vibration, the sampled points ...

Abstract: This paper describes the use of subharmonic sampling to distinguish between different instability types in milling. It is demonstrated that sampling time-domain milling signals at integer multiples of the tooth period ...

Abstract: This paper provides time domain simulation and experimental results for surface location error (SLE) and surface roughness when machining under both stable (forced vibration) and unstable (period-2 bifurcation) conditions. ...

Abstract: This study examined the energy transfer ratio (ETR) of Central Mine Equipment (CME) automatic standard penetration test (SPT) hammers utilizing a large database of SPT energy measurements. The database consisted of energy ...

Abstract: Abstract. Bird strikes on aircraft present a growing concern to wildlife preservation efforts and pose safety and economic challenges in aviation and urban design that amalgamate a sociotechnical system. Recent evidence ...

Abstract: Abstract. The transition from the cyber–physical system to the cyber–physical–social system (CPSS) incorporates the social space as an independent entity that interacts with cyber and physical spaces, thereby incorporating ...
