Analysis of Machining Parameters in WEDM of Al/SiCp20 MMC Using Taguchi‐Based Grey‐Fuzzy Approach

Modelling and Simulation in Engineering, Volume 2019, Issue 1, 2019., 2019
Aluminium silicate metal matrix composite (AlSiC MMC) is satisfying the requirement of material with good mechanical, thermal properties, and good wear resistance. But the difficulties during the machining are the main hurdles to its replacement for other materials. Wire electric discharge machining (WEDM) is a very effective process used for this type

Numerical Analysis of the Influence of Electrode Inclination on Temperature Distribution during GMAW Overlaying

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In the work, an analysis of the influence of electrode inclination on the distribution of temperature in the weld overlaying has been conducted. In the analytical description of the temperature field, a volumetric heat source model with an inclined axis with respect to the direction of surfacing was adopted.

Additive Manufacturing Technologies: An Overview about 3D Printing Methods and Future Prospects

Complexity, Volume 2019, Issue 1, 2019., 2019
The use of conventional manufacturing methods is mainly limited by the size of the production run and the geometrical complexity of the component, and as a result we are occasionally forced to use processes and tools that increase the final cost of the element being produced. Additive manufacturing techniques provide major competitive advantages due to
