Thank your for your very interesting presentation dealing with cutting tool wear monitoring in drilling based on data obtained from the control system of the machine tool.
In your presentation, the effectiveness of this method for tool wear monitoring is demonstrated by experimentally verified increase of torque values with increasing number of drilled holes.
Did you carry out a correlation between detected torque values and extent of tool wear, e.g. the wear land size, so that it becomes possible to decide when the critical tool wear level is approaching and the tool needs to be changed?
We also partially performed correlation among torque signal and types of tool wear apeared. However, we are currently working on algorithm to be able to use internal data from control system when machining with small diameter tools, under eight milimeters.
In case of eny other questions feel free to contact me.
