In-process ultra-high frequency evaluation of abrasives

Objective



Grinding is a very complex process of increasing potential in material removal rate and surface finish quality which requires real-time in-process monitoring of grinding and dressing operations, diagnosis of process states and the use of sensor based expert control system. As a first step towards a fully integrated process monitoring, diagnostic and control system for grinding and dressing operations it is the aim of the project to develop the appropriate metrology and to find correlations of signal patterns with process states. This will include the development of ultra-high frequency capacitive and piezoelectric sensors with a bandwidth of up to at least 1 MHz and the development of a high speed signal analysis network for signal conditioning and data processing based upon neural techniques (bandwidth of at least 10 MHz).

Status:
In progress.
