Ukusebenza okuyisisekelo kwezixhumi kungahlukaniswa ngezigaba ezintathu: ukusebenza kwemishini, ukusebenza kukagesi kanye nokusebenza kwemvelo. Enye impahla ebalulekile yemishini impilo yemishini yesixhumi. Impilo yemishini empeleni iyinkomba yokuqina, ebizwa ngokuthi ukusebenza komshini ku-GB5095 ejwayelekile kazwelonke. Kuthatha ukufakwa okukodwa kanye nokukhipha okukodwa njengomjikelezo, futhi kuthatha ukuthi isixhumi singakwazi yini ukuqedela umsebenzi waso wokuxhumana (njengevelu yokumelana nokuxhumana) ngemva komjikelezo oshiwo wokufaka nokukhipha njengesisekelo sokwahlulela.
Impahla yemishini Ngokuphathelene nomsebenzi wokuxhuma, amandla okufaka kanye nokukhipha kuyimpahla ebalulekile yemishini. Ukufaka nokukhipha{1}}amandla okukhipha ahlukaniswe amandla okufaka kanye -nokukhipha amandla ({3}}amandla okukhipha{3}abuye abizwe ngokuthi amandla okuhlukanisa), futhi izidingo zawo zihlukile. Kunezinhlinzeko zamandla okufaka aphezulu kanye namandla okuhlukanisa amancane emazingeni afanele, okubonisa ukuthi ngokombono wokusetshenziswa, amandla okufaka mancane (ngakho kunezakhiwo ezinamandla aphansi okufaka i-LIF futhi awekho amandla okufaka i-ZIF), futhi uma amandla okuhlukanisa emancane kakhulu, ukwethembeka kokuxhumana kuzothinteka. Amandla okufaka nawokuhoxisa kanye nempilo yobumishini yesixhumi kuhlobene nesakhiwo sokuxhumana (ingcindezi enhle), ikhwalithi yokumboza yengxenye yokuxhumana (i-coefficient ye-sliding friction) kanye nokunemba kobukhulu (ukuqondanisa) kokuhlelwa kokuxhumana.
