The energy distribution of the incident light spot on position-sensitive detector (PSD) screen is uneven and the output coordinate value is the energy centre of the light spot. Measurement error caused by the deviation between the geometric and gravity centre of the light spot will occur. The...
Recent studies show that the combined use of large-volume metrology (LVM) systems (e.g., laser trackers, rotary-laser automatic theodolites, photogrammetric systems, etc.) can lead to a systematic reduction in measurement uncertainty and a better exploitation of the available equipment. The...
This paper proposes two greedy heuristics based on an iterated insertion technique to solve the flexible job shop scheduling problem with transportation time's constraint. The approaches treat the two sub-problems of: the assignment of machines to operations and the sequencing of the operations...
This paper introduces an electrochemical drilling process which is efficient in fabricating micro-holes, in order to study the influences of ultra short pulse voltage and high speed spiral micro electrode on the machining accuracy and machining efficiency of micro electrochemical drilling, the...
This investigation focused on optimisation of self-propelled rotary turning process conditions through an integrated multi-objective optimisation approach. The machining experiments are conducted for machining hardened EN24 (SAE4340) steel with TiN-coated tungsten carbide rotary insert. Two...
