Surface roughness

A surface roughness ne daya daga cikin key sharudda ga kimantawa da ƙarfin sassa. Halakar da fuskantar da yanki a ƙarƙashin rinjayar m lodi saboda mafi girma mataki na danniya da natsuwa. A karshen, bi da bi, ya auku a lokacin akwai magudi. A kasan surface roughness, da ƙananan yiwuwar samuwar fasa saboda karfe gajiya. Processing sassa (kammala, polishing, lapping, da dai sauransu) na taimaka wa wani gagarumin karuwa da gajiya ƙarfi iyaka.

A kasan surface roughness, da mafi alheri da anticorrosion kaddarorin da abubuwa. Wannan ne da muhimmanci musamman a lokuta inda da aiki da kayayyakin da ba zai yiwu su yi amfani da m shafi. Irin wannan daki-daki, musamman, za a iya dangana engine cylinders.

Low surface roughness ne na bayar da muhimmanci a cikin pairings cewa hadu a kan yanayin da thermal watsin, tightness. Wannan qara ikon yin tunãni electromagnetic, haske da ultrasonic kalaman. Bugu da kari, da asarar zama karami fiye da electromagnetic makamashi a cikin resonating tsarin waveguides zama ƙananan capacitance wayoyin. rage-rage matsayin gas sha da kuma outgassing a injin na'urorin yana yuwuwa, game da shi tsaftacewa sassa na adsorbed da ake wãtsarwa, tururi, da gas.

Kimantawa surface ingancin masana sun lura da fuskantarwa Lines kafa bayan machining ko wasu magani. Wannan bangaren yana da wani sakamako a kan mataki na ƙarfin labaru dangane, landings yaƙĩni karko. A zanen ya kamata a tattauna mayar da hankali shanyewar jiki na cikin mawuyacin lokuta. Irin wannan bukatar iya misali, tashi dangane da shugabanci na motsi na jet na gas ko ruwa a kan workpiece ko da shugabanci na zumunta motsi (zamiya) na conjugates. Rage lalacewa da m yiwu yayin da matching da shugabanci na m sassa da zamiya shugabanci.

A waviness na surface kuma a low roughness ko da yaushe hadu da high daidaituwa da cewa shi ne saboda ba kawai ga aiki yanayin conjugate abubuwa, amma kuma a kan bukatar samun m results for ma'aunai a cikin masana'antu. Irin wannan workpieces iya amfani dasu don yin kayayyakin m bayyanar ko don samar saukaka ciki abubuwa tsabta.

Ji na surface roughness aka yi idan ya cancanta. Manuniya an saita daidai da aikin manufar da samfurin. Idan bukatun ga ingancin bayani ba su yi, to, da iko ba a yi a kan matakin da roughness. Ba dole ne a ce cewa da'awar ba sun hada da wani kima da lahani (gaban bawo, misali). A wannan batun, da aiwatar da iko da surface roughness, iko da rinjayar lahani ne cire gaba daya. A wasu lokuta, da bukatun za a iya kafa da mutum sassa na yanki daya.

roughness kimantawa da aka yi a kan profile magudi (yawanci kẽta). Don samar da wannan sashe da jirgin sama. Tare da manufar raba daga sauran roughness magudi tare da mun gwada manyan matakai, ta jarrabawa aka yi a cikin wasu, wajen iyakance yankin.

Quantification da kuma daidaita da aka yi da shida sigogi. Saboda haka, shan la'akari da uku high-Yunƙurin siga ga kimantawa da surface roughness (Ra, Rz, Rmax), biyu stepper (S, SM), da kuma index, wanda kayyade zumunta tsawon na goyon bayan profile (TP).
