Amathuluzi okulinganisa endabuko kanye nemishini yokulinganisa edidiyelwe (i-CMM) zombili zisetshenziselwa ukulinganisa ubukhulu, kodwa kukhona umehluko omkhulu kubuchwepheshe, ukunemba kanye nokusetshenziswa. Ukuqonda lo mehluko kubalulekile ekukhetheni indlela yokulinganisa efaneleke kakhulu yezidingo ezithile zokukhiqiza.
Amathuluzi okulinganisa endabuko, njenge-calipers, ama-micrometer, ama-height gauge, njll., ayizinto eziphathwa ngesandla ezithembele ekusebenzeni ngesandla. Zifanelekela ukulinganisa okulula futhi zivame ukusetshenziswa ezindaweni zokukhiqiza ezincane. Ngokuphambene nalokho, umshini wokulinganisa ohlanganisiwe uwuhlelo oluyinkimbinkimbi olulawulwa yikhompyutha olusebenzisa ama-probe ukukala izakhiwo zomzimba zento ngokunemba okuphezulu. Ikhono le-CMM lokubamba inani elikhulu lamaphuzu edatha lenza kube kuhle kakhulu kuma-geometri ayinkimbinkimbi kanye nokulinganisa okunembile kakhulu.
Omunye umehluko omkhulu phakathi kwamathuluzi okulinganisa endabuko kanye nemishini yokulinganisa edidiyelwe yizinga lokunemba. Amathuluzi endabuko anemikhawulo maqondana nokunemba, ngokuvamile ahlinzeka ngokunemba ngaphakathi kwama-micron ambalwa. Ama-CMM, ngakolunye uhlangothi, angafinyelela ukunemba kwe-sub-micron, okwenza afaneleke ezimbonini ezidinga ukubekezelelana okuqinile kakhulu, njengokukhiqiza izindiza kanye nezimoto.
Omunye umehluko obalulekile ijubane nokusebenza kahle kokulinganisa. Amathuluzi endabuko adinga ukusebenza ngesandla futhi avame ukuhamba kancane uma kuqhathaniswa nama-CMM, angaskena ngokuzenzakalelayo futhi alinganise amaphuzu amaningi ku-workpiece ngesikhathi esincane. Lokhu kwenza ama-CMM asebenze kahle kakhulu ekukhiqizweni okukhulu kanye nezingxenye eziyinkimbinkimbi.
Ngaphezu kwalokho, ukuguquguquka kokulinganisa kuwumehluko ophawulekayo phakathi kwamathuluzi endabuko nama-CMM. Ngenkathi amathuluzi endabuko ekhawulelwe ekulinganisweni okuqondile kanye namajiyomethri alula, ama-CMM angalinganisa izimo eziyinkimbinkimbi ze-3D kanye nemidwebo, okwenza afaneleke ukuhlola izingxenye eziyinkimbinkimbi nokwenza ukuhlolwa okuphelele kokulawula ikhwalithi.
Ngamafuphi, amathuluzi okulinganisa endabuko afanelekela ukulinganisa okuyisisekelo kanye nokusebenza kwezinga elincane, kuyilapho ama-CMM enikeza amakhono athuthukile maqondana nokunemba, isivinini kanye nokuguquguquka. Ukuqonda umehluko phakathi kwalezi zindlela ezimbili zokulinganisa kubalulekile ekukhetheni ikhambi elifanele kakhulu ukuhlangabezana nezidingo ezithile zokukhiqiza.
