    Notes: Summary The adult fruit piercing moth,Othreis fullonia, a native of the indo-Malaysian region, causes severe damage to fruits grown throughout the tropical and subtropical belt from Africa through Asia and Australia to the Pacific Islands. Plants of the family Menispermaceae and the genusErythrina (Fabaceae) serve as larval hosts but the adult moths prefer Menispermaceae plants for oviposition. In Africa, Asia and Australia, the moth does not lay eggs onErythrina since members of the Menispermaceae are abundant. However in the insular Pacific region, where most islands have few or no species of Menispermaceae, the introduced fruit piercing moth utilizesErythrina as an alternate larval host, and either depletes, endangers or causes the possible extinction of Menispermaceae.

    Investigation of wire EDM control variables on kerf width for Al6063/SiC/Al 2 O 3 composite by response surface methodology (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-09-21
    Description: This investigation presents the consequence of Wire EDM process variables over the kerf width (KW) of Al6063/SiC/Al 2 O 3 hybrid composite which is fabricated by stir cast method. 31 experiments were conducted on the basis of response surface methodology central composite design. Kerf width is picked as the quality objective. The important coefficients are gotten by achieving successfully an Analysis of Variance (ANOVA) at the 5 % assurance interval. The outcomes discover that KW is much more impacted by Pulse on time, Pulse off time, current and control speed and little of their interactions action or influence. To predict the average kerf width, a mathematical regression model was developed. The forecasted value of optimum kerf width is 0.265 mm for Pulse on time (100), Pulse off time (48), current (200) along with control speed (60%).The Pulse on time is most influential variable for the kerf width. The results have been analyzed using Minitab version 18 so...

    An estimating the effect of control process variables on kerf width in wire EDM of AZ91 magnesium alloy by Taguchi method (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-09-21
    Description: The target of the current research study is to contemplate the impacts of diversecontrol parameters in WEDM, for example, wire tension, wire speed, discharge duration on and Pulse off time over kerf width (KW) and to get the ideal arrangements of process parameters. The trial work comprises of machining of Magnesium AZ91 alloy material utilizing Wire EDM (WEDM).The wire (tool) material was brass wire by means of zinc coated. The observations of the cutting process are based on L27 Taguchi’s array for optimizing the control variables for these composite. The criticalness of each cutting parameters are associated to the most impacting factors which influences the procedure reactions. The ideal cutting variables are selected from the outcomes. Minitab V.18 software are developed for establishing good relationship between machining variables, such as wire feed, pulse duration time, wire tension & pulse off duration with the cutting control process criteria kerf width.
