The purpose of this paper is to illustrate how Six Sigma methodology has been applied in a small-scale foundry industry to improve the overall first-pass material yield and quality, with a view to the product and the process.
The researchers have reported this paper based on a case study carried out in industry using the Six Sigma Define, Measure, Analyze, Improve and Control (DMAIC) and its application in improving the manufacturing process of a foundry shop.
Identified root causes are validated and countermeasures are implemented for improvement. As a result of this case study, the overall first-pass yield of the sand casting process is improved to 78.88% from the previous yield of 67%. For product-specific case, yield is improved by 18% through the improved gating system design. Sigma level of the process is improved to 3.08 from baseline 2.21. Key lessons learned from this case study are mentioned in the current study.
This case study provides a standard road map and motivates small-scale foundry industries to implement Six Sigma methodology for productivity improvement, especially in jobbing foundry. The presented paper is based on a single case study, and the results are limited to the company only. Also, one of the reasons for low process yield is slag creation, which is not covered here, as it is a concern of the material quality supplied by the vendor. However, the approach of this paper is generic for learning perspective.
This case study provides a standard road map and motivates small-scale foundry industries to implement Six Sigma methodology for productivity improvement, especially in jobbing foundry. Through the effective application of Six Sigma quality initiative, how a quantum jump in financial aspect could be gain, has been demonstrated.
This research study showcases step-by-step implementation of Six Sigma-DMAIC methodology at a small-scale foundry industry. This paper could serve as a unique roadmap for practitioners and academicians to improve the material productivity of the foundry industry both ways, product and process.
This paper seeks to investigate the work of a small company involved in researching techniques and designing equipment for assembly automation.
The development of a fully automated CNC machine for drilling aircraft wing sub‐assemblies is described. The importance of accurate process simulation is discussed, and a research project combining physics‐based gaming hardware with factory simulation software is presented. Its application to the laying‐up of carbon composite materials is explained.
Effective and affordable simulation software is essential to small companies to avoid risk in one‐off projects. AMTRI leverages new developments and puts them together to form powerful new systems. The automation of innovative composite processing is intrinsically connected with the behaviour of the material itself.
The paper points out the importance of automation to the future of European manufacturing, in the light of increasing fuel costs.

Graham Engineering, a UK company specialising in the manufacture of large complex components for high‐tech industries has pioneered the application of 3D laser trimming and welding of stainless steel and other difficult‐to‐process pressings and fabrications. It uses a Prima Optima 3D laser profiler, one of the largest built by the Italian company, for this work and examples are described from the nuclear, aerospace, domestic heating and telecommunications industries. One of the largest is a nuclear containment vessel manufactured in 6 mm stainless steel, requiring over 18 m of laser welded seams produced in a single pass compared with a root and four capping runs required when TIG welded. Quality and strength are also superior to TIG. Other components produced in the Prima machine include mild steel pressings for an aerospace customer, satellite dishes for a telecommunications company and stainless steel hot water cylinders marketed by Graham Engineering company.
