In the current investigation. a multi response optimization technique based on Taguchi method coupled with Grey relational analysis is planned for wire-EDM operations on ballistic grade aluminium alloy for armour applications. Experiments have been performed with four machining variables: pulse-on time. pulse-off time. https://www.roneverhart.com/M-M-s-Milk-Chocolate-Candy-Teal-2LB-Bag/
