OPTIMIZATION OF DRESSING VARIABLES IN A SINGLE POINT DIAMOND DRESSING: A GOAL PROGRAMMING APPROACH

Abstract

The dressing depth of cut and the dressing lead arc the two important dressing variables which significantly affect the surface roughness and specific grinding energy. Normally, to ensure good grinding performance, it is desirable to have, among other things, low surface roughness and, at the same time, low specific grinding energy. A finely dressed wheel gives low surface roughness but at the same time, a higher specific grinding energy, and vice versa. Therefore, both criteria of good grinding performance are in conflict and cannot be achieved simultaneously. To take care of such a conflicting situation, an application of the goal programming technique is described in this paper which determines optimal values of the dressing variables. For this purpose, experiments were conducted to establish functional relationships between the dressing variables and the surface roughness as well as specific grinding energy under reciprocating plunge surface grinding conditions. A sensitivity analysis is carried out t...
