CIRP CMMO 2021

Keynote Speakers

Professor, Dr. I. S. Jawahir is a Professor of Mechanical Engineering, James F. Hardymon Endowed Chair in Manufacturing Systems, and the Founding Director of the Institute for Sustainable Manufacturing (ISM) at the University of Kentucky (Lexington, KY, USA).

Professor Jawahir’s current research activities include: predictive modeling and optimization of machining processes; and sustainable product design and manufacturing processes. His early pioneering work on dry, near-dry (also known as MQL) and cryogenic machining/processing of materials, and the more recent foundational work on sustainable manufacturing are well-recognized world-wide. He has produced over 440 technical research papers, including more than 150 refereed journal papers, and has been awarded with 4 U.S. patents. He has delivered 68 keynote papers at plenary sessions in major international conferences and over 150 invited presentations in 37 countries. Professor Jawahir is a Fellow of three major professional societies: CIRP (International Academy for Production Engineering); ASME (American Society of Mechanical Engineers); and SME (Society of Manufacturing Engineers). He is the Founding Editor-in-Chief of the International Journal of Sustainable Manufacturing, and the Technical Editor of the Journal of Machining Science and Technology. Professor Jawahir founded the CIRP International Conference Series on Modeling of Machining Operations in 1998.  Professor Jawahir founded the CIRP’s Working Group on Surface Integrity in 2007 and served as the Chairman of this international collaborative research group for four years. In 2005, he founded the ASME’s Research Committee on Sustainable Products and Processes and served as the Founding Chairman for six years (2005-11). He also co-founded the CIRP Conference Series on Surface Integrity in 2012. In October 2018, Professor Jawahir organized and hosted the 16th Global Conference on Sustainable Manufacturing (GCSM) in Lexington, KY, USA and served as the Conference Chairman. Professor Jawahir received numerous awards and honors for his research and academic achievement over the years. Most recent awards include the 2013 ASME Milton C. Shaw Manufacturing Research Medal for his outstanding research contributions to fundamental understanding of sustainable manufacturing processes, and the 2015 William Johnson International Gold Medal for his lifelong achievements and contributions to materials processing research and education.

He will be giving a Keynote Lecture entitled Modeling of Machining Operations: Past, Present and Future.

A short Abstract of the Lecture: 

Machining processes continue to be the largest among all manufacturing processes in terms of revenues generated and the volumes of production for applications. Modeling of machining operations is a significant pre-manufactuirng activity which helps the product and process designers and planneers tremendously for increasing manufacturing productivity with enhanced product quality at reduced costs. Historically, over the last several decades the research community has developed a wide range of analytical, numerical, and hybrid models including AI-based models for various machining operations. However, the effectiveness of much of these models is very limited due to complexities involved in modeling associated with variabilities in work material properties, and cutting tool and machine tool conditions. Also, the over-simplistic approaches adopted in modeling seem to provide only idealized solutions with practicability of models largely lacking. This presentation will critically review the past modeling efforts and discuss some of the major issues with past modeling efforts, and will present a summary of recent developments in modeling. Current modeling activities and future directions in machining with complex cutting tools and varying cooling conditions will be presented with a view to achieving sustainable machining focusing on promoting product and process innovation for closed-loop manufacturing, thus minimizing the negative environmental impact (with reduced toxic dispersion and health hazards), reducing energy consumption, wastes, and material utilization, and increasing the societal and economic benefits in machining. Modeling and optimization challenges with be discussed summarizing the outlook with new opportunities.

Dr. Jani Kenda is a Technology and Digitalization Manager at Hidira Corporation, a world-recognized automotive and industrial technology company based in Slovenia.

Dr. Kenda was in his early carreer a researcher at the Faculty of Mechanical Engineering in Ljubljana, at the Laboratory for Machining – LABOD. His main work was focused on finishing processes. In 2013 he finished a PhD Degree in Mechanical Engineering. Dr. Kenda is an experienced researcher with a background in design and optimization of manufacturing processes, technology planning, high performance finishing processes. He has also experience in design of experiments and characterization of production systems and operations. He is currently employed in Hidria as a Technology and Digitalization Manager within the business unit of Advancetec, working on new projects, focusing mostly on sensors: cylinder pressure sensors, injection mold pressure sensors, high temperature sensors, torque sensors and so on.

He will be presenting a Keynote Lecture entitled Modeling and Digital Twin of Manufacturing Processes in Industrial Environment.

A short Abstract of the Lecture:

Product and its components are usually small, precise, and made of difficult to machine materials. To ensure suitable efficiency on the way from design, prototypes, and final production, it is mandatory to focus on three crucial elements: digital twins/modeling, clean production, and productivity. Those are directly influencing development phase cycles, cost reduction in term of expensive prototypes and ensure low scrap rate in production.
