Research Experience/ Facilities developed/ Software developed:

  • Engaged in research since 1971, in the field of Electrochemical Machining (Unconventional Manufacturing Process) and obtained Ph.D. based on the work done at IIT Madras.
  • A relocation cum machining fixture was designed and fabricated to facilitate studies on surface formation in ECM. Original approach using Laser Doppler Velocimeter was applied in the study of surface formation. A basic experimental setup of ECM was fabricated and utilised for research. Mathematical analysis using Fourier series and finite element methods for the study of anodic smoothing in ECM were done. Polarisation measurements in ECM in actual machining were carried out.  Influence of electro-lyte flow velocity on anodic smoothing was investigated. Developed computer programs to study anodic smoothing and shaping. Electrochemical studies on Nickel machining undertaken.
  • Macro and Micro machining of 2-D and 3-D shapes in Glass. Design of tooling and multistage machining using combination of Ultrasonic machining and Chemical machining.
  • Abrasive waterjet  machining of quartz, aluminuium and granite undertaken. Facility modifications for performance studies on the use of local garnet abrasives for abrasive waterjet cutting, recycling and recharging.
  • A relocation cum burnishing setup for ball burnishing studies was designed and developed. Special tools for ball burnishing and vibratory burnishing based on mechanical design were fabricated. Studies on the plastic deformation aspects of ball burnished surfaces are in progress. Corrosion resistance of ball burnished surfaces are  undertaien.
  • Research in the area of Industrial safety in foundary environment using Delphi studies was completed.  A novel method of classifying jobs/industries based on intrinsic hazard potential using Hazard Index was developed.
  • Material Requirement Planning under variable demand is being analysed. A new lot sizing policy named Dynamic Least Incremental Cost (DLIC) policy has been developed. Its performance is found to be superior compared to the existing policies both in static and dynamic cases.
  • The power of Petrinets is exploited for modelling, simulation and control of complex flexible manufacturing and assembly systems (since asynchronous and concurrent).  Considering the limitations of available Petrinet types, especially in scheduling activities, a new class called Priority Nets were developed with improved capability and compactness.
  • Project management  applications to manufacturing  require efficient tools. In this context Petrinets and Genetic Algorithms are used. Resource levelling and resource allocation can be done more effectively.
  • Software was developed for AGV control in FMS environment. Packages for FMS layout and flexible assembly systems considering transportation activities and task restrictions were developed.
  • Evaluation of flexibility of flexible systems, implementation of Just-In-Time in FMS, virtual cell formation are undertaken.
  • Developed a heuristic to schedule a general m x n floorshop for unidirectional flows, flow in G.T.Cells etc.
  • Development of software for AS/RS for modelling, scheduling and control. Integration of AS/RS with FMS and Cyclic Mode of Operational Policy for AS/RS.  Use of Stochastic Coloured Petrinets.
  • Development of software for operational planning and scheduling of Flexible Manufac-turing Systems considering tooling constraints.
  • Use of Genetic Algorithms for improving the performance FMS, Lot sizing and Project  Management ( Resource levelling and resource allocation).
  • Multi objective optimisation of flow shops using Genetic algorithms.
  • Flexibility analysis of  FMS.
  • At The University of West Indies, Trinidad and Tobago- Fabrication of ECM equipment for teaching and basic research.
  • At the University of Mauritius – Fabrication of ECM, AJM units for Teaching and basic research.
