In this study, Al-Mg-Si alloy AA6061-T6 plates were joined in a seawater environment using the Submerged Friction Stir Welding (SFSW) technique, and process parameters optimized Taguchi L9 orthogonal arrays (OA). The considered tool rotational speed, transverse pin geometry. MINITAB-17 software was used to analyze responses signal-to-noise (S/N) ratio analysis of variance (ANOVA). optimum for t...

The small blind internal thread (SBIT) plays a very important role to firmly fastening some functional components on the cover of 3C electronic products. was made in hole using fluteless forming tap (FFT) without producing chips. However, four geometric parameters FFT (tool width (W), tooth root diameter (D2), front-end (Df), and angle (?)) will affect filling rate (f) minimum torque (T) tappin...

The transverse bowing greatly affects the accuracy of roll-forming asymmetric corrugated channels (ACC). In order to control this defect, paper first elucidates its mechanism production. Then, is explored by finite element method (FEM) using ABAQUS 2016 software and effects forming parameters are analyzed. Also, a linear regression model built Minitab 19 evaluate their effects, which standard v...

In this study, a 3 mm thickness of AlSi10Mg Casted alloy plates was used in the friction stir welding process. The experimentations were conducted Using design experiment to shorten number experiments and get optimal parameters by utilizing Gray relational analysis based on ultimate tensile hardness test results. Orthogonal array L9 (33) three main stages for each parameter, where tool velocity...

Abstract Rice is the leading staple food in Indonesia and one of largest production centers West Java Province. Of wide local varieties rice Java, only a few have been inventoried characterized for their morphological characteristics. This study aims to determine Java’s phenotypic diversity plants. Inventory characterization plants was carried out from 2018 2021 seven districts (Sukabumi, Suban...

The research investigates synthesized Nano-structured PbO2 using ball milling. The structure and morphology of the samples were determined in the process of milling by means of XRD and SEM. The size of particles was estimated through DLS analysis. The TEM image of the synthesized powder verifies the achievement of Nano dimensions. Design and analyses of the results using Taguchi methodology rev...

Pose estimation is one of the vital issues in mobile robot navigation. Odometry data can be fused with absolute position measurements to provide better and more reliable pose estimation. This paper deals with the determination of better relative localization of a two wheeled differential drive robot by means of odometry by considering the influence of parameters namely weight, velocity, wheel p...
