Description of 2-D (X-Z coordinates) values at machined rod for estimating the volume of chipping

Developed multi-shaped abrasive-coated tools.

First time in the scientific world, a glass machined rod is quantified by a coordinate measuring machine

Tooling solution provided for glass industries: To attain the least chipping and cracking around the through and blank holes
