Lapping IS a critical technology In a number of precIsion manufactUring appllcallons PrevIous research has focused primarily on mechanisms of material removal and the effects of Input variables on material removal rate (MRR) The behaVior of MRR In lapping processes when the standard Input variables-workpiece pressure, reialive velOCity of workpiece and lap, and relative material and abraSive hardness-are carefully controlled has not been extensively explored Exploration of thiS controlled-condition situation IS Important because of ItS prevalence In production environments Experimental data presented here show that the MRR for lapping IS not constant, but Instead It varies With time and can be described as a random variable. In general, mean MRR decreases With time A preliminary description IS presented that shows the behaVior of MRR With time The removal of waste slurry from the lapping plate IS shown to be a Critical Issue for the desIgn of the lapping plate and the lapping procedure.
