Design for Quality, Manufacturing and Assembly

By Prof. Palaniappan Ramu   |   IIT Madras
In the context of product design, it is very important to appreciate the limitations of a design from manufacturing and assembly perspective and to produce high quality products at low cost. This course will introduce methods that can provide guidance to design teams in simplifying product structure to reduce manufacturing and assembly costs, quantify improvements and how robust design concepts can be used for ensuring quality. This course aims at introducing the need to account for variability, mathematically represent it, formulate it and control it. Concepts such as quality, robustness, six sigma and orthogonal array will be discussed. 

INTENDED AUDIENCE : Final year UG students, Masters and PhD Students, Engineering practitioners in industry
PREREQUISITES : Basic knowledge on manufacturing such as manufacturing techniques and probability
INDUSTRY SUPPORT : Fiat Chrysler Automotive, Daimler India, Cyient, Saint Gobain

    INSTRUCTOR BIO



    Prof. Palaniappan Ramu
    ’s research interest revolves around optimization and treating uncertainties in product and process design to obtain reliable, robust and quality designs. Most of his work is focused on reduction of computer or physical experiments, building better metamodels, intelligently explore design space and enable better predictions and optimal designs under uncertainties
