In my case, tungsten carbide drill wear rate has been calculated using mass loss method and compare with the Uniaxial compressive strength.
but when the UCS is high, Los angele abrasion % is low , and wear rate of the drill bit for that particular type of rock in high. i am little confuse in this case.
Please provide the related work for the conformtions.
From my point of view you need to change the hard metal quality of the drill to a different quality that had smaller wear resistance.
For example, you can change K10 quality to K20 quality. The fist had higher wear resistance and the second bigger toughness.
As the abrasion percentage is more for medium grained sandstone of UCS is 16.5 MPa. But wear rate of drill bit is low around 2.5mg/min
But if you change the methodology to measure wear from weigth loss to wear heigth over the tool edge?
Sir, even though if we used different method. Higher the wear rate of the drill bit for less los Angeles abrasion pe
