Manufacturing Technology Assignment 2: Design for Assembly Analysis

This assignment solution analyzes the design of an AC gas control valve assembly, focusing on design for assembly principles. It includes a detailed analysis of the original design, followed by a proposed redesign of the pressure control subassembly to improve design efficiency. The solution then delves into various manufacturing processes, including machining parameters like chip load, surface speed, material removal rate, and machining time calculations. It explores keyway cutting using CNC milling and conventional/unconventional machining methods. The assignment also covers 3D printing processes suitable for the components and addresses quality control aspects, including surface finish, feed rate optimization, process capability analysis, control charts, and acceptance sampling plans. The solution concludes with an analysis of operational characteristic curves and a discussion of producer's and customer's risks. This assignment showcases a comprehensive understanding of manufacturing technologies and quality control methodologies.
