Characterization of a Bronze Based Powder for Direct Selective Laser Sintering of Metals
No full textDimensional Analysis in Selective Laser Melting
Full text linkThis paper aims to use dimensional analysis technique for evaluating the properties of laser sintered components manufactured with Selective Laser Melting (SLM) process from metallic powders. The complexity of SLM does not allow to define an exhaustive mathematical model which involves all governing parameters and, therefore, the dimensional analysis might be a powerful tool for the expression of output parameters as function of dimensionless numbers appropriately defined from the input parameters set. As an example of the developed procedure, the paper explains the construction of a response function for the expression of relative density
Definition and Analysis of Uncertainty Contributors in the Dimensional Measurement of Bronze Sintered Samples
Full text linkThe paper concerns the definition and estimation of uncertainty elements. This topic is matched with Direct Metal Selective Laser Sintering used for manufacturing the samples.
The UNI ENV ISO 14253-2: 2003 standard deals with uncertainty sources in dimensional measurement. This paper treats just those ones regarding measurement procedure, measurement equipment and workpiece. The aim of this paper is estimating combined standard uncertainty.
Measurement repeatability, workpiece fixing and number of points for the definition of geometric elements arise from measurement procedure. Measurement equipment uncertainty is connected with Maximum Permissible Error. As far as workpiece uncertainty components, surface roughness, form error and temperature are checked
