Isantya sokususa umhlwa yeumthungo odityanisiweyo umbhobho
Oko kukuthi, i-total kinetic energy E isetyenziswe kumbhobho wensimbi nge-abrasive ngexesha leyunithi kunye ne-kinetic energy E1 ye-abrasive-grain abrasive.Isantya sokususa i-rust yombhobho wensimbi kuxhomekeke kuhlobo lwe-abrasive kunye nokufuduka kwe-abrasive.Kwifomula: ubungakanani bokutshiza (ukuphosa) kwe-m abrasive;isantya sokubaleka se-V abrasive;ubungakanani be-m1 enye ye-abrasive.Ubungakanani be-m buhambelana nezinga lokutyumza kwe-abrasive.Ubungakanani besantya sokutyumza buchaphazela ngokuthe ngqo umdla womsebenzi wokulahla umphezulu kunye neendleko zezixhobo zokususa irusi.Xa isixhobo silungisiwe, u-m uhlala ehleli kwaye u-y uhlala engatshintshi, ngoko ke u-E naye uhlala engatshintshi.Nangona kunjalo, ngenxa yokutyunyuzwa kwe-abrasive, i-m1 iyatshintsha, ngoko ngokuqhelekileyo, i-abrasive enezinga eliphantsi lokulahlekelwa kufuneka ikhethwe, ehambelana nokuphucula isantya sokucoca kunye nokwandisa ubomi be-blade.
