7ε News (2012)

 

2012 saw the launch of the 7Epsilon website and roadshows were arranged at various cities in India, England, Scotland, Sweden and Poland.

 

7Epsilon presentations were recorded in India and YouTube video’s are made available on the 7Epsilon website.

 

7 Epsilon Presentation at ICME in Birmingham and Scotland.

 

Dr. Rajesh Ransing, FICME from Swansea University, was welcomed for a 7Epsilon paper presentation at the first meeting in 2013. Dr. Ransing explained that given a list of measurable factors and their ranges, influencing factors can be identified by analysis of data using 7Epsilon penalty matrices and bubble diagrams. The main effects and interactions among parameters can be studied with evidence in your data. Reuse in-process data, discover influencing factors settings using penalty matrices, and retain foundry specific process knowledge is the 7Epsilon motto. Retain knowledge derived from this exercise for long term benefit.

 

 

Report on 7 EPSILON 2012 Roadshows in India

 

Written by S.H. Arjunwadkar, Chairman, NCTS India

 

This concept of 7 Epsilon is accepted in Europe as a part of Europe 2020 vision in European Council Meeting. The Swansea University (U.K.) is leading the consortium for promotion of this concept. Through its efforts, NCTS has been able to include India in the list of European countries. As a part of promotion and to study views of Indian Foundry Industry, a series of seminars were organized in various locations in India, from 14 th April 2012 to 23 rd April 2012. The total of 421 participants from seven chapters attended the seminars. The program was held at Ahmadabad, Pune, Kolhapur, Belgaum, Shimoga, Chennai and Coimbatore chapters.

Chairman NCTS Mr. Sham Arjunwadkar coordinated the sessions and gave a brief about the concept of ‘7 Epsilon beyond 6 Sigma Thinking - for Zero Defect Casting Manufacturing’. The need for zero defect manufacturing and reduction in rejection by 1 % can save Rs.215 Crores for the Indian foundry Industry. The importance for such a tool was enormous as the number of variables in Foundry process and sub processes is large. There is also interdependence of variables and variation of one can affect many more properties in different ways. Changing one variable at a time means huge cost and efforts in development and there is also hesitation and reservation by the managements in making too many changes at the same time. That is why need for such a tool.

 

Dr. Rajesh Ransing, taking the lead from here explained the concept of 7 Epsilon. The term 7 Epsilon is coined by Dr Patricia Caballero of Spain and this concept is led by Swansea University. The approach is –

 

Knowledge retention and reuse, Knowledge Discovery and Culture of Innovation.

 

This concept explains FPR – (Factor Process Relationship). All the interactions between various parameters and its intensity must be understood to get the desired final result. With the help of simple tools and necessary software this study is possible.

 

Further a consortium for the purpose is envisaged as 7 Epsilon Consortium which comprises of representatives from – World Foundry Organisation, Various Foundry and research organisations from countries like U.K., Spain, Germany, Poland, Sweden, IIT Bombay and a software maker. As a member of consortium the technical articles with WFO and other data bases may be made available to all, resulting in exchange of knowledge and culture of Innovation.

 

Dr. Ransing also agreed to work with the foundries on case studies for reducing the rejection. Generally, the response from the participants was very positive and hopes the Indian Foundry Industry will get benefit from this association with the Consortium.
