SME NIST-ATP Technology Dissemination Workshop on Intelligent Optimization and Control of Grinding Processes |

This is the first of three technology dissemination workshops for the National Institute of Standard and Technology’s Advanced Technology Program (NIST-ATP) on Intelligent Optimization and Control of Grinding Processes. It is being held in conjunction with the 35th NAMRC at the University of Michigan at Ann Arbor, MichiganThe workshops are designed to broadly disseminate technologies developed through the 3-year NIST-ATP program to grinding industries and grinding practitioners. The intended workshop participants are NAMRI/SME members and grinding professionals from many metalworking industries, such as automotive, aerospace, medical device, precision machinery, and electronics. Grinding processes are usually highly non-linear and multivariable, thus rendering difficulties in establishing accurate analytical models. Often their input-output relationships are ill defined and most existing analytical models only describe partial relationships between design (input) variables and process (output) variables. In addition, the input-output relations often are available only in heuristic form or in empirical data. In such cases, an attempt to optimize or control the process faces a major challenge. Conventional feedback control or optimization techniques encounter severe limitations in dealing with such problems. In practice, when a new process is designed, engineers often have to utilize all available information such as analytical models, expert knowledge, experimental data, handbooks, and vendor recommendations. Integrating all the heterogeneous information and designing an optimal solution is not an easy task, often requiring a long lead-time and a number of trial-and-error iterations. In view of the complex nature of the grinding process and stringent finish, accuracy and surface integrity requirements of the ground part, a Generalized Intelligent Grinding Advisory System (GIGAS) was developed to provide a more robust and scientific approach to the optimization and control of grinding processes. This workshop will cover the GIGAS technology fundamentals and its applications and case studies for centerless and internal grinding operations. |
