Feedrate scheduling is one of the most critical technologies in CNC machining, requiring a reasonable balance between efficiency and quality.This paper proposes a jerk-continuous feedrate smoothing (JCFS) method to generate a low-vibration and smooth feedrate profile for non-uniform rational B-spline (NURBS) interpolation.Firstly, the segmentation
Gender and science studies in Latin America have questioned the unequal structures of the scientific field in the region using as analytical pivot a particular and homogeneous idea of women scientist as opposed to men scientist.From these analytical approaches aspects such as ethnicity, race and sexuality, which are central to the shaping of the fe
Now, the calculation of beams, lying on the solid elastic foundation is fulfilled with us- ing different model of elastic foundation.One of the most common is a model, based on the Accessoires Résine hypothesis of a proportion betweenthe reaction of the foundation at the point with the coordi- nate x and slump at the same point (the hypothesis of
Electrochemical exfoliation of graphene is an environmentally friendly method, which enables mass production.Herein, three ionic liquids (ILs) with the same imidazole cation were used to exfoliate graphite into functionalized Watch Accessories graphene, as a lubricant additive in an acetonitrile solution.Chemical and structural characterization rev
Abstract MAGNESIUM 1:1 In view of the fuzziness and randomness of the safety evaluation of the channel navigation environment, a risk evaluation model of the channel navigation is established with the set-valued statistics and the gray theory.A safety evaluation index system of channel navigation consisting of first-level indexes for the natural en
