@Shubrajit, as u mentioned the disk is circular. Then while doing expt., u have to fix up with particular track diameter (d), u know liner velocity V=( pai X d X N)/(60), also V=D/t where D= track distance travelled in m, t= time taken in sec. By this u can calculate wear track distance
Why not simply calculating the circumference of the wear track and then multiplying it by the number of total rounds done? I don't understand.

you should know your disk rpm.
Then distance = 2(phi)*rpm*time*distance between disc centre to pin centre.

Thankx Amin..your input is really worthy of thinking.....
I would like to add one more line along with Mr Amin Ezazi. I think, LVDT is mostly used in reciprocating rigs. However, for accurate measurement of total sliding distance in rotatng Pin-on-Disc, RVDT is the most appropriate sensor!.

Dear prof i want to understand the concept of the sliding distance in wear test on the pin disk machine- Badges
