Analysis of the Flatness Form Error in Binder Jetting Process as Affected by the Inclination Angle

open access: yesMetals, 2022
Binder jetting (BJ) has demonstrated high competitiveness among additive manufacturing processes on account of its high production rate at a low material cost. However, both the design procedure and the process for BJ have to be further developed, aiming

A novel method to control stress distribution and machining-induced deformation for thin-walled metallic parts

open access: yesHigh Temperature Materials and Processes, 2022
In the precision machining of thin-walled planar components, the initial residual stress of the workpiece could lead to subsequent deformation after machining, which influences the geometrical accuracy of the final parts. Generally, conventional methods,

High accuracy geometric Hermite interpolation [PDF]

open access: yesComputer Aided Geometric Design, 1987
In natürlicher Verallgemeinerung der Hermiteschen Standardinterpolation werden für parametrisierte ebene Kurven interpolierende kubische Splines p(i) bestimmt. Dabei sind die Knotenpunkte und in jedem Knotenpunkt Tangente und Krümmung vorgeschrieben. Die Komponenten von p(i) sind kubische Polynome auf den Parameterintervallen \((i,i+1)\).

Current Concept of Geometrical Accuracy [PDF]

open access: yesResearch Papers Faculty of Materials Science and Technology Slovak University of Technology, 2014
Abstract Within the solving VEGA 1/0615/12 research project "Influence of 5-axis grinding parameters on the shank cutter´s geometric accuracy", the research team will measure and evaluate geometrical accuracy of the produced parts. They will use the contemporary measurement technology (for example the optical 3D scanners).
