Operation Bulletin of Ladies Sports Bra with Machine Layout Plan

Introduction: A bra, brassiere short is a shape-fitting undergarment designed to support and cover the breasts of the wearer. Bras are made for a variety of purposes, including increasing the breast size of a woman, producing cleavage or other cosmetic, style or practical requirements.

When women work out, more pressure and impacts are put on their breasts than during their daily activities. The movement and bouncing of women's breasts can create a force of up to 5 times their actual weight. Wearing a sports bra provides them the support and comfort they need to do physical activity.

Generally, a machine layout plan is made by following an operation breakdown. Because of an operation breakdown, we get the proper idea about which part will join one after another and select the machine for that operation. We have also known how many machine and workers need for each operation from the machine layout plan.
