Condition Monitoring is More Than Just Data Collection. It sounds simple - routine monitoring of your rotating equipment results in data necessary for deriving information about the condition of your equipment. But if the data isn't accurate, your analysis won't be either. If you can't acquire data in a timely manner, you'll miss early ...
In grinding process monitoring, the primary goal is essentially to decide whether an abrasive layer is sufficiently good for grinding or not. In tool condition monitoring, various type of sensors are used to monitor vibration, sound, acoustic emission, motor current, cutting force etc. to predict the state of the cutting tool.
12%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 …
