Koj puas paub qhov Kev Pom Zoo ntawm Daim Ntawv thiab Txoj Haujlwm yog dab tsi?
Geometric kam rau ua yog hais txog qhov tso cai hloov pauv ntawm cov duab tiag tiag thiab txoj haujlwm tiag tiag ntawm ib feem los ntawm cov duab zoo tagnrho thiab txoj haujlwm zoo tagnrho.
Geometric kam rau ua muaj xws li kev kam rau siab thiab txoj hauj lwm kam rau ua. Ib feem yog tsim los ntawm cov ntsiab lus, kab, thiab qhov chaw, thiab cov ntsiab lus, kab, thiab qhov chaw hu ua cov ntsiab lus. Cov ntsiab lus tiag tiag ntawm cov khoom siv machined ib txwm muaj qhov yuam kev cuam tshuam nrog cov ntsiab lus zoo, suav nrog cov duab tsis raug thiab qhov tsis ua haujlwm. Hom kev ua yuam kev no cuam tshuam rau kev ua haujlwm ntawm cov khoom siv kho tshuab, thiab kev sib haum xeeb yuav tsum tau teev tseg thaum tsim thiab cim rau ntawm daim duab raws li cov qauv cim. Nyob ib ncig ntawm xyoo 1950, cov teb chaws muaj kev lag luam muaj daim ntawv thiab txoj haujlwm kam rau ua qauv. Lub koom haum International rau Standardization (ISO) tau luam tawm cov qauv geometric kam rau ua nyob rau hauv 1969, thiab pom zoo rau geometric tolerance detection txoj cai thiab txoj kev nyob rau hauv 1978. Tuam Tshoj tshaj tawm cov qauv thiab txoj hauj lwm kam rau ua nyob rau hauv 1980, nrog rau cov kev cai xeem. Lub siab ntev thiab txoj hauj lwm kam rau ua yog raug xa mus rau qhov kev siab ntev rau luv luv.
Cov txheej txheem ua tiav tsis yog tsuas yog muaj qhov ntev ntev, tab sis kuj tseem muaj qhov sib txawv ntawm qhov sib txawv ntawm cov duab tiag tiag lossis kev sib koom ua ke ntawm cov ntsiab lus, kab thiab qhov chaw uas ua rau cov duab geometric ntawm ib feem thiab cov duab thiab txoj hauj lwm sib koom tau teev tseg los ntawm qhov zoo tshaj plaws geometry. Qhov sib txawv ntawm cov duab no yog qhov kev kam rau siab, thiab qhov sib txawv ntawm qhov sib koom ua ke yog txoj hauj lwm kam rau ua, sib sau ua ke hu ua kev kam rau siab ntawm daim ntawv thiab txoj hauj lwm.
Thaum peb tham txog "Kev Ua Siab ntev ntawm Daim Ntawv thiab Txoj Haujlwm", nws yog ob qho tib si theoretical thiab kev txawj ntse, koj puas paub ntau npaum li cas? Hauv kev tsim khoom, yog tias peb to taub yuam kev ntawm geometric kam rau ua cim rau ntawm daim duab, nws yuav ua rau kev soj ntsuam thiab kev ua tiav ntawm qhov kev xav tau, thiab txawm tias yuav ua rau muaj qhov tshwm sim loj.
