Agricultural waste such as sugarcane and paddy are common during harvesting to production process. Sometimes they burned after the harvest process, consequently environmental problem got multiply. Demand for Composite Material inflate recently, because lighter stronger than Polyethylene Plastic. Filler in composite materials is expensive requires precise design. The aim of this research create ...

Analisis penyebab tepat diharapkan dapat meningkatkan efisiensi, produktivitas, mengurangi biaya produksi di manufaktur. Analisa menggambarkan ha...

Boeing South Carolina builds the Boeing 787 Dreamliner, the world's first composite-skinned wide-body jet. This new manufacturing facility is evolving to meet the demands of building this complex aircraft. One of the challenges faced by this site is providing the manufacturing workforce with the best tools for the job in an efficient manner. Two different research streams investigate this high-...

This study introduces the fuzzy theory approach as an enhancement to traditional failure mode, effect, and criticality analysis (FMECA) method in order address its limitations, which primarily stem from subjectivity a lack of quantitative analysis. The proposed method, referred FMECA improvement based on comprehensive evaluation, aims quantify qualitative aspect provides detailed outline proced...

At present, the replacement of disc cutters tunnel boring machine (TBM) is a very important and difficult manual operation. It meaningful to study TBM with robot. In this paper, machining assembly deviation new integrated cutter developed by our research group modeled analyzed using improved Jacobian–Torsor model, analysis results are verified experiments. On basis, aiming at possible radial an...

The movement of air around a rotating milling cutter is investigated experimentally by using the optical non-intrusive method PIV (Particle Image Velocimetry). located next to flat surface simulating processed material. Flow studied in three planes axial × radial direction with phases 90°, 180° and 270° from point closest desk. timing has been synchronized rotation. We observed plumes governed ...

Seeing the world around you is like drinking from a firehose. The flood of information that enters the eyes could easily overwhelm the capacity of the visual system. To solve this problem, a mechanism-attention-allows selective processing of the information relevant to current goals. As the eminent physiological psychologist Helmholtz [HN2], [HN3], [HN4] noted over a hundred years ago, even wit...

Blog posts are often informally written, poorly structured, rife with spelling and grammatical errors, and feature non-traditional content. These characteristics make them difficult to process with standard language analysis tools. Performing linguistic analysis on blogs is plagued by two additional problems: (i) the presence of spam blogs and spam comments and (ii) extraneous non-content inclu...

Kinematics of a particular five-axis milling machine can drastically change the machining accuracy. Therefore, the reduction of the kinematics error is an important problem associated with the tool path planning. Our newoptimizationmethod employs a closed formof the kinematics error represented as a function of the positions of the cutter contact points. The closed form is derived from the inve...
