Abstract
Grinding is a finishing process in machining operations, and the topology of the
grinding tool is responsible for producing the desired result on the surface of the
machined material. The tool topology is modeled in the dressing process and
precision is therefore extremely important. This study presents a solution in the
monitoring of the dressing process, using a digital signal processor (DSP)
operating in real time to detect the optimal dressing moment. To confirm the
monitoring efficiency by DSP, the results were compared with those of a data
acquisition system (DAQ) and offline processing. The method employed here
consisted of analyzing the acoustic emission and electrical power signal by
applying the DPO and DPKS parameters. The analysis of the results allowed us
to conclude that the application of the DPO and DPKS parameters can be
substituted by processing of the mean acoustic emission signal, thus reducing the
computational effort.

1 Introduction
Grinding is a workpiece finishing process that accounts for approximately 25%
of all machining processes. Because this operation is usually the last one in the
manufacturing sequence, all the time and quality-related problems generated
along the chain of processes involved in the fabrication of a component must be
