Analysis and improvement of HP Deskjet 3920 printer using the boothroyd-dewhurst DFA method

Abstract

The objective of this thesis is to apply Boothroyd-Dewhurst DFA method on product to improve the assembly time and cost of the product The parts can be improved by using classification system for manual insertion and handling time without eliminate their function Printer model HP Deskjet 3920 had been choosing to be analyse and improve by applying Boothroyd-Dewhurst DFA method. Solidworks 2007 has been used as a CAD software in draw part by part of printer and analyse in terms of von mises stress.
