Recently, an increasing number of parts have been produced using additive manufacturing technology. They are no longer simply prototypes but structural whose mechanical characteristics must be known before printing. One the weaknesses 3D printing is significant variability in dimensions and geometrical properties printed parts. These depend on specific parameters environmental conditions. This study aims to determine influence two parameters, namely, orientation positioning platform humidity...

Predicting the behavior and mechanical properties of 3D-printed parts is crucial for 3D printer users. This study conducted experimental investigations on Onyx to identify most important printing parameters. These parameters were specimen positioning number walls. The results indicated that specimens oriented in XZ direction 48% stiffer than those XY 54% ZX direction. Additionally, demonstrated walls significantly influenced orientations but had no effect orientation. Young's modulus...

Additive Manufacturing (AM) using Fused Deposition Modelling (FDM) is a 3D printing technique that can produce parts with complex shapes. Multiple types of printers are available in the market, so it essential to understand their potential manufacture meet industry standards. This study aims evaluate industrial Markforged X7 printer by assessing its performance based on QS9000 quality standard. The indices, including Cp index and Cpk index, were determined for different dimensions,...

The lightweighting of 3D-printed components is achievable by using infill patterns and the ability to adjust their density. In this context, performing a mechanical characterization numerical simulation printed parts imperative. This manuscript conducts experimental investigations on composites (onyx/glass fibers) that consider pattern, walls, roofs, floors samples. A homogenization approach was adopted identify elastic parameters patterns. results demonstrated tool’s effectiveness in...

The usage of additive manufacturing techniques has increased dramatically in recent years. Fabricated parts are no longer simple prototypes, but rather structural components whose mechanical characteristics must be understood before printing. One the weaknesses 3D printing is high variability dimensional, geometric, and properties, which due to combination various parameters, including number walls, roofs, floors, filling patterns, layer thickness. This study aims predict properties onyx...

The 3D printing of continuous-fiber composites is currently relevant to engineers and researchers. This study aims characterize predict the mechanical properties Onyx/glass fiber specimens printed using printing. work assesses impact glass parameters on behavior parts proposes analytical numerical methods properties. A physicochemical analysis was conducted continuous fibers. also investigated composite parts. results indicate that 3D-printed fibers consist nylon, fibers, voids (porosity),...

In the context of product quality, methods that can be used to estimate machining defects and predict causes these are one important factors a manufacturing process. The two approaches presented in this article determine defects. first approach uses Small Displacement Torsor (SDT) concept [BM] displacement dispersions (translations rotations) machined surfaces. second one, which takes into account form errors surface (i.e. twist, comber, undulation), geometrical model based on modal shape's...

Tolerance analysis has been the topic of many research publications in recent past. It is a method to evaluate quality products terms functional tolerances. Most assessment procedures process planning are based on trial-and-error runs, which costly and time consuming. There also distinct lack focus area plan verification input variables generated from experiments. This article first provides an overview tolerance analysis. The limits previous studies explored. A overcome problems...

The objective of tolerancing methods is to limit the variations a characteristic while trying minimize cost realization. Traditionally expressed in form an interval (min, max), it can also be different as case inertial tolerancing. principle consists mean square deviation relationship target. This new method has many properties that property additivity offers. However, when several characteristics are added give resulting characteristic, leads significant tightening around target process...

The finite element simulation is a very useful tool in the deep drawing industry. It used more particularly for development and validation of new stamping tools. allows to decrease cost time tooling design set up. But one most important difficulties have good agreement between real process comes from definition numerical conditions (mesh, punch travel speed, limit conditions,…) parameters which model material behavior.Indeed, press shop, when sheet changes, often variation formed part...

The paper presents results of research a milling process, which include experimental studies associated with determination cutting forces. Cutting depth is parameter that was varied in the course measurements. Analytical models were constructed for force prediction on basis data obtained tool geometry, cross-section removed material layer and regimes. A two inserts used experiments: during process one insert removing layer, while other idle. evaluation developed single insert. accuracy...

The quality of fixtures plays an important role in product during manufacturing, measuring or assembly. Finding methods for evaluating a fixture’s quality, which may depend on workpiece errors, fixture influences clamping force, friction, etc., is necessary to improve the quality. This paper proposes indicators that are used estimating based localization repeatability. Here, will be considered following different cases: (1) considering only influence geometric parameters (types) fixture, (2)...
