Ukuze kwandiswe isikhathi sokuphila kwesikhunta, ubulukhuni bezinto ezizonqunywa nabo buvame ukwanda. Ngakho-ke, izidingo eziphakeme zibekwe phambili empilweni yamathuluzi kanye nokusebenza kahle kokucubungula emishinini enesivinini esikhulu yezinto ezinobulukhuni obuphezulu. Imvamisa, singakhetha izigayo kumaphuzu amathathu:
1. Khetha uhlobo lokumboza ithuluzi ngokusho kohlobo nobulukhuni be-workpiece okufanele icutshungulwe. Isibonelo, lapho ucubungula i-carbon steel nezinye izinto zokusebenza ngobulukhuni obungaphansi kwe-HRC40, i-MIRACLE40 enamathelayo evela ku-Comprehensive Materials Company ingakhethwa. Lapho ucubungula insimbi ye-alloy S, insimbi yamathuluzi nezinye izinto zokusebenza ezinobunzima obungaba ngu-HRC50, ukunamathela kwe-MIRACLE kungakhethwa. Lapho wenza ama-workpieces ngobulukhuni obuphezulu, ungakhetha ukuma kwethuluzi, i-carbide material, kanye ne-coating, konke okuyi-MIRACLE coating for high-hardness machining of high-hardness materials.
2. Khetha ukwakheka kwentamo yokusika isigayo sokuphela ngokusho komumo we-workpiece ezocutshungulwa. Ukuma kwentamo yesigayo sokuphela kuhlukaniswe ngohlobo olujwayelekile, uhlobo lwentamo ende kanye nohlobo lwentamo ye-tapered, engakhethwa ngokusho kokucubungula nokuma kwe-workpiece. Uhlobo lwentamo ende kanye nohlobo lwentamo ene-tapered lungasetshenziselwa ukumba okujulile, futhi i-angle yokuphazamiseka kufanele icatshangelwe lapho ukhetha phakathi kokubili. Ngesikhathi esifanayo, uma kuqhathaniswa nohlobo olude lwentamo, i-tapered neck end mill inokuqina okuphezulu, okungathuthukisa izimo zokusika futhi kufinyelele ukunemba okuhle kwemishini. I-tapered neck end mill kufanele ikhethwe ngangokunokwenzeka.
3. Khetha izigayo zokugcina ngokunemba okuhlukile kwekhanda lebhola ngokusho kokunemba komshini. Ukunemba kwe-arc yezigayo zokugcina kuvame ukuba ngu-±10 μm, kodwa kukhona nezigayo zokugcina ezino-±5 μm, ezingakhethwa ngesikhathi sokucubungula.
