The dynamics of grinding glass with Trizact™ diamond tile (Conference Presentation)
Author(s): John A. Gagliardi; Vincent Romero

Paper Abstract

Flat glass finishing has traditionally been performed in batch processes that apply constant loads in double sided lapping and polishing operations. This paper simulates the constant rate grinding of glass that might be used in high volume applications where a more continuous process approach, such as double disk grinding (DDG), might be advantageous. The dynamics of grinding glass can be demonstrated uniquely and simply through the use of an analysis method first described by Lindsay and Hahn1 for bonded wheels. Measuring the normal and tangential forces during constant rate removal processes allows one to calculate the volumetric material removal parameter and the specific power, as well as threshold forces and specific energy. Performance comparisons between Trizact™ Diamond Tile (TDT) abrasive grade, glass type, lubricant type & concentration, and the TDT diamond abrasive concentration can be effectively compared to identify improved removal performance for a given type of glass. Such an analysis can potentially help improve constant rate glass grinding operations.
