Thanks Dr. Ned I could download it. I have a question:
I am PhD student in mining engineering.
Actually, for my thesis I want to measure drill bit wear by taking
subsequent photos from drill bit after drilling and then use image
processing to measure wear area of the bit.
After e.g. a 100 m drilling I will take photo from bit surface and then compare with previous one. The problem is shortening the bit how can effect this in the analsys?

Many thanks for attention
