Manufacturing Strategy & Operations: Reflections On Key Current Issues: Challenges And Associated Human Resource Implications, Lorraine Mcgrath
Manufacturing Strategy & Operations: Reflections On Key Current Issues: Challenges And Associated Human Resource Implications, Lorraine Mcgrath
Books/Book chapters
This chapter evaluates the current issues and challenges in defining a company’s manufacturing strategy and its production operations in consideration of the contemporary shift to low cost manufacturing locations. Competitive priorities of cost, quality, delivery and flexibility are reviewed. The structural and infrastructure elements of a manufacturing strategy are outlined. Mitigating risks in a global arena are reviewed. Collaborative efforts, including the cultural and personality issues of being human are included in the discussion of managing diversity in such a highly competitive and challenging enterprise resource planning environment.

In the paper, the micro deformation of oxide scale in hot strip rolling has been investigated with considering the friction effect. The finite element simulation of the micro deformation of oxide scale has been successfully conducted, and the calculated surface roughness is compared with the measured value, which shows a good agreement. A crystal plasticity finite element method (CPFEM) model was also successfully developed to analyse the surface roughness transfer during metal manufacturing. The simulation results show a good agreement with the experimental results in the flattening of surface asperity, and the surface roughness decreases significantly with an increase of …

This study considers the use of the gas tungsten arc (GTA) welding process in conjunction with 'cold' wire addition to give layer-wise build-up of thin walled structures, simulating those commonly found in aerospace applications, which may in the future be manufactured by additive means. Taguchi DOE and multiple regression analysis methods have been applied to quantitatively establish relationships between common process parameters including arc length, arc current, travel speed and wire feed speed and resulting weld bead geometries and actual metal deposition rates. Mathematical expressions for build-up height, thickness and surface roughness are presented and evaluated against experimental data, with …
