Edge effects with the Preston equation for a circular tool and workpiece
Alberto Cordero-Dávila,Jorge González-García,María Pedrayes-López,Luis Alberto Aguilar-Chiu,Jorge Cuautle-Cortés,Carlos Robledo-Sanchez +5 more
TL;DR: A new model in which the pressure is higher at the edge is applied to the case of a circular tool that polishes a circular workpiece and correctly predicts that a greater amount of material is removed from the edge of the workpiece.
Journal ArticleDOI
Ronchi and Hartmann tests with the same mathematical theory
TL;DR: A common mathematical model is established for the Ronchi and Hartmann tests and for interpretation of the Ronchigrams as level curves of the components of the transversal aberrations.
Proceedings ArticleDOI
Edge effects with Preston equation
Esteban Luna-Aguilar,Alberto Cordero-Dávila,Jorge González,Manuel Nunez-Alfonso,Victor Cabrera,Carlos Robledo-Sanchez,Jorge Cuautle-Cortez,Maria H. Pedrayes +7 more
TL;DR: In this paper, a new pressure distribution model was proposed to calculate the wear produced by a square tool on a glass border moving along straight lines, which presents like a skin effect.
Journal ArticleDOI
Conic that best fits an off-axis conic section.
Octavio Cardona-Nunez,Alejandro Cornejo-Rodriguez,J. Rufino Diaz-Uribe,Alberto Cordero-Dávila,J. Pedraza-Contreras +4 more
TL;DR: This method is based on the method of continuum least squares to obtain the vertex’s curvature and conic Constant of the fitted conic on-axis, given the curvature at the vertex and the conic constant of the parent conic from where the authors want the section and the size of that section.
Journal ArticleDOI
Null Hartmann and Ronchi-Hartmann tests
TL;DR: Assuming the Ronchi and the Hartmann tests to be null tests, it was able to design special screens for each test that produce aligned straight fringes and a square array for the observed patterns.
