i have doubt regarding temperature measurement technique in metal machining has already been exploited in rock cutting with minor modification.
in my case i have used a newly fabricated thermocouple to measure the bit-rock interface temperature during rotary drilling. three operational parameters has been considered for this experiment. embedded thermocouple method has been implemented in my work (placing of thermocouple inside the rock sample at a nominal distance to measure the temperature and extracted data). core sample of NX size is used for this experiment.
now what is the major application and uses of this work (laboratory or industry).
Where could we have more information about this tool? You talk about tool while rotary drilling, but where is placed, how work's it?
Interface between tool and rock is 0.5 mm. based on the trial and error method. and fixed as near as possible. where the maximum temperature is measured.
During drilling, the drill bits become very hot due to friction. As a result of heating, wear increases in drill bits. Knowing the amount of drill bit heating of the formation is an important criterion for estimating wear. Therefore, this study may play an important role in the prediction of wear.
