In modern manufacturing engineering, tolerance synthesis is important because it directly e€ ects product quality and manufacturing cost. This paper introduces a new method for tolerance synthesis of machining parts. The new method consists of three steps. First, machining parts are evaluated using the second-order fuzzy comprehensive evaluation (FCE). Then, a mathematical model for tolerance a...

The need for functionally graded material (FGM) parts has surfaced with the development of material science and additive manufacturing techniques. Direct Metal Deposition (DMD) processes can locally deposit different metallic powders to produce FGM parts. Yet inappropriate mixing of materials without considering the influence of varying dilution rates and the variation of material properties ca...

Several new technologies collectively referred to as solid freeform fabrication have been developed in the last decade for use in the rapid prototyping of solid three dimensional parts. These include stereolithography, photosolidi cation, solid ground curing, 3D printing, fused deposition modeling, ballistic particle manufacturing, selective laser sintering, laminated object manufacturing, and ...

In the present turbulent times, survival and success of any organization increasingly depends on competitiveness. The Small-Medium Enterprises (SMEs) play an important role in both developed and developing country economies. To remain competitive, SMEs must adopt strategic technologies and innovative management practices to survive. In finding ways to increase competitiveness and productivity, ...

One of the key challenges in additive manufacturing plastic goods using Fused Filament Fabrication (FFF) technology is to ensure their strength. The low strength polymer materials and distinct anisotropy mechanical properties limit use 3D printing as an alternative traditional small-scale production technologies. most promising solution goal increasing printed application continuous fiber reinf...
