Whilst this study only allowed the edging of a limited number of parts, the results of higher RPM grinding are promising. At present working conditions, an increase of peripheral speed from today's 45 mn/sec to 80 m/sec with an adapted wheel allows higher feed rates. By increasing speed up to Vc 100 m/sec, a feed rate of 24 m/sec could be reached on 4 mm glass with a fair edge quality. This means an increase of about 50 % of today's usual feed rates. Prerequisite is a specially adapted high precision wheel enabling Vc up to 125 m/sec. Moreover an optimisation of cooling system and coolant will probably bring significant additional improvements. Adjustments of flow rate and pressure have also to be considered. As restraint, it must be mentioned: 1) The wheel specification was chosen in order to give better result at higher RPM. This might explain some bad edge quality at lower RPM. 2) spindle and wheel lifes should be duly examined if no negative effect. A production test for confirmation will be conducted in November 1997.
