Current Concept of Geometrical Accuracy [PDF]

Research 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).

Effect of Printing Speed and Layer Height on Geometrical Accuracy of FDM-Printed Resolution Holes of PETG Artifacts

IECMA 2022, 2022
: Poly Ethylene Terephthalate Glycol (PETG)-filament gives excellent layer adhesion, thus it is widely used in Fused Deposition Modeling (FDM). To achieve process repeatability, process parameters and product’s geometrical accuracy should be correlated ...
