The effect of machining parameters on the surface roughness in dry-turning Ti6Al4V alloy using an experimental design method was investigated. A mathematical equation based on the response surface methodology was established to fully understand the influence of machining parameters (cutting speed, feed rate, and depth of cut) on the surface roughness.

This research project investigates the influence of decoration and decorating on a fashion design practice, exploring the transformative effects of both in relation to surface and structure. Decoration is considered an after-effect, an element that can be differentiated from the object it adheres to, sometimes making it superfluous to the object’s function. In this project I consider decoration as having its own function – the ability, through its link to the ‘exterior’ world, to transform the shape, appearance and materials of forms by modifying their facade.
