Ukuqedela okubushelelezi komshini kukhiqiza indawo enencazelo ye-arithmetic, eyaziwa nangokuthi i-Ra, engu-1.6 μm (63 μin).Njengokuqedwa komshini, ukuqedwa okubushelelezi okwenziwe ngomshini nakho kunikeza ukususwa konqenqema olubukhali kanye nokususa ingxenye.Njengoba ingaphezulu lishelela kunendawo yokuqeda evamile, amamaki nokungapheleli kubonakala kancane.Ukuphela komshini okubushelelezi akutholakali ngokuqedwa kwezimonyo.

Ezinye izingxenye zidinga ukuqedwa kwendawo okushelelayo kunaleyo enikezwa ngokuqedwa okujwayelekile.Ezimweni ezinjalo, umsebenzi womshini owengeziwe wenziwa ukuze kuncishiswe ubulukhuni obungaphezulu kube yinani elamukelekayo.Ezingxenyeni ezikhiqizwa ngemishini ye-CNC, imisebenzi enjalo ngokuvamile ingangezwa kwinqubo yokukhiqiza ukuze konge isikhathi.Ezingxenyeni ezikhiqizwe ngemishini engeyona eye-CNC noma imishini eminingi, i-CNC machining isetshenziselwa ukwenziwa kwemishini ebushelelezi ngemuva kokuphela kokukhiqiza futhi ingxenye isilungile.
