Tool condition monitoring of aluminum oxide grinding
· The grinding process is situated at the end of the machining chain where geometric and dimensional characteristics and high-quality surface are required. The constant use of cutting tool (grinding wheel) causes loss of its sharpness and clogging of the pores among the abrasive grains. In this context the dressing operation is necessary to correct these and other problems related to its use
