9. Lawula ukuphuma ngaphakathi kwinqanaba lokunyamezelana ukuze uqinisekise umthwalo wokusika okufanayo. Ukugqithisa okugqithiseleyo kwinqanaba lokusika kuya kwenza amandla okusika angalingani kwaye aholele ngokulula kumazinyo aqhekekileyo. Ngokulungelelanisa ukufakwa kwesixhobo kunye neeparitha zokucubungula, lawula ukuphuma ngaphakathi kwinqanaba lokunyamezela.
10. Ukwandisa i-angle yokuphambuka ephambili kwaye unciphise ububanzi bokusika. I-angle encinci kakhulu yokuphambuka iya kwandisa ububanzi bokusika kwaye ikhokelela ngokulula kumazinyo aqhekekileyo. Ngokweemfuno zokusetyenzwa, khetha ubungakanani obufanelekileyo be-engile yokuphambuka.
11. Nika ingqalelo ekususeni iitshiphusi kwangexesha, ngakumbi xa uphinda ukhupha imingxuma enzulu okanye imingxuma eyimfama. Ukuqokelela kwe-chip kuya kuchaphazela umphumo wokusika kwaye kulula ukukhokelela kumazinyo aqhekekileyo. Sebenzisa indlela efanelekileyo yokususa iitshiphusi kwangethuba.
12. Nika ingqalelo umgangatho wokugaya kwaye ugweme amazinyo aqhekekileyo ngexesha lokugaya. Xa ugaya i-reamer, khetha iiparamitha ezifanelekileyo zokusika kunye neendlela zokugaya ukuqinisekisa umgangatho kunye namandla amazinyo.

1. Ukugqithiswa kwesibonelelo sokubuyisela kwakhona.
2. Xa ukuhlaziya imingxuma e-tapered, ukuhanjiswa kwezibonelelo ezinqabileyo kunye nokugqiba ukuhlaziya kunye nokukhethwa kweeparitha zokusika azifanelekanga.
3. Indawo ye-chip yamazinyo e-remer incinci,
