Research paper thumbnail of Local Tool Path Smoothing Based on Symmetrical NURBS Transition Curve with Look Ahead Optimal Method: Experimental and Analytical Study

A lot of local corner smoothing methods which inset a tiny spline curve at the corners have been proposed in literature. However, there exists potential overlap of the two adjacent spline curves while smoothing, and still no optimal solution for eliminating the overlaps. To optimally eliminate the overlaps and smooth the transition curve curvature in real-time, a symmetrical Non-uniform rational B-spline (NURBS) curve transition based on look ahead optimal method is proposed in this paper, by scanning a set of unconstrained pre-cornering transition curve information, analysing the overlap type and backward determining the optimal transition length, thus fully use the linear segment length of each corner, Thus fully increasing the feedrate at the corners. continuity, analytical expression of the curvature extreme, approximation error c...

Machine tool eval-uation involves an essential decision using imprecise and vague information, and plays a major role to improve the productivity and flexibility in manufacturing. The aim of this study is to present an integrated approach for decision-making in machine tool selection. This paper is focused on the integration of a consistent fuzzy AHP (Analytic Hierarchy Process) and a fuzzy COmplex PRoportional ASsessment (COPRAS) for multi-attribute decision-making in selecting the most suitable machine tool. In this method, the fuzzy linguistic refer-ence relation is integrated into AHP to handle the imprecise and vague information, and to simplify the data collection for the pair-wise comparison matrix of the AHP which determines the weights of attributes. The output of the fuzzy AHP is imported into the fuzzy COPRAS meth...

A laboratory experiment with two lifting loads are considered in this study: (1) 1 kg and (2) 5 kg. Each subject adjusts his frequency of lifting using a psychophysical approach. The subjects are instructed to perform combined manual material handling task as fast as they could over a period of 30 minutes without exhausting themselves or becoming overheated. The physiological response on energy expenditure is recorded during the experimental sessions. The ratings of perceived exertion (RPE) for four body parts (forearms, upper arm, lower back and entire body) are also collected after the subjects have completed the task. The key findings of the study are the percentage difference of the MALF between novice and worker subject were 4.72% for 1 kg and 5.21% for 5 kg. The result revealed that although novice and worker did not differ significantly in MALF but ...
