檢測(鑄鐵平板)鑄鐵平臺工作面技巧：

　　1、計(ji)算法(fa)：應(ying)用(yong)計(ji)算公(gong)式獲得鑄鐵平(ping)臺、鑄鐵平(ping)板平(ping)面度誤(wu)差值。該(gai)法(fa)有計(ji)算jing確的優(you)點，但需(xu)事先判準低點，否則將(jiang)造成計(ji)算錯誤(wu)或影響其(qi)計(ji)算準確度。

　　2、旋轉法：是將鑄鐵平臺、鑄鐵平板測(ce)基面(mian)(mian)(mian)(mian)(mian)經過適當(dang)變換(huan)(旋轉或(huo)平(ping)(ping)移)，使(shi)鑄(zhu)(zhu)鐵(tie)平(ping)(ping)臺、鑄(zhu)(zhu)鐵(tie)平(ping)(ping)板(ban)測(ce)量基面(mian)(mian)(mian)(mian)(mian)和評(ping)定(ding)(ding)基面(mian)(mian)(mian)(mian)(mian)重(zhong)合，獲得(de)符合小(xiao)條(tiao)(tiao)件的(de)(de)位置(zhi)，通過測(ce)量出(chu)鑄(zhu)(zhu)鐵(tie)平(ping)(ping)臺、鑄(zhu)(zhu)鐵(tie)平(ping)(ping)板(ban)數(shu)據(ju)(ju)的(de)(de)交換(huan)獲取平(ping)(ping)面(mian)(mian)(mian)(mian)(mian)度(du)誤(wu)差(cha)。該(gai)法(fa)(fa)不(bu)需使(shi)用(yong)繪圖或(huo)計(ji)(ji)算(suan)(suan)工(gong)具，有簡便易行(xing)的(de)(de)優(you)點，具體操作時常需做(zuo)多次旋轉，對(dui)不(bu)熟練(lian)者效率不(bu)。我公司(si)認為(wei)(wei)該(gai)法(fa)(fa)是(shi)檢(jian)驗鑄(zhu)(zhu)鐵(tie)平(ping)(ping)臺、鑄(zhu)(zhu)鐵(tie)平(ping)(ping)板(ban)基本(ben)的(de)(de)方法(fa)(fa)，只要掌握旋轉要領，終必能(neng)達(da)到(dao)(dao)目的(de)(de)。指出(chu)，上(shang)述兩(liang)種方法(fa)(fa)在(zai)(zai)使(shi)用(yong)中具有同等價(jia)值(zhi)(zhi)，可(ke)(ke)按其掌握程度(du)、測(ce)量條(tiao)(tiao)件靈活選用(yong)。在(zai)(zai)實際工(gong)作中采用(yong)哪一(yi)種方法(fa)(fa)，取決于工(gong)作現場的(de)(de)具體條(tiao)(tiao)件和人員的(de)(de) 長與水平(ping)(ping)而定(ding)(ding)。用(yong)計(ji)(ji)算(suan)(suan)法(fa)(fa)獲取鑄(zhu)(zhu)鐵(tie)平(ping)(ping)臺、鑄(zhu)(zhu)鐵(tie)平(ping)(ping)板(ban)對(dui)角(jiao)(jiao)(jiao)線(xian)法(fa)(fa)原(yuan)(yuan)(yuan)始數(shu)據(ju)(ju)的(de)(de)方法(fa)(fa)對(dui)角(jiao)(jiao)(jiao)線(xian)法(fa)(fa)是(shi)以對(dui)角(jiao)(jiao)(jiao)線(xian)平(ping)(ping)面(mian)(mian)(mian)(mian)(mian)為(wei)(wei)理(li)想(xiang)平(ping)(ping)面(mian)(mian)(mian)(mian)(mian)評(ping)定(ding)(ding)平(ping)(ping)面(mian)(mian)(mian)(mian)(mian)度(du)的(de)(de)一(yi)種數(shu)據(ju)(ju)算(suan)(suan)得(de)方法(fa)(fa)。數(shu)據(ju)(ju)處理(li)是(shi)將水平(ping)(ping)儀或(huo)自(zi)準直儀得(de)到(dao)(dao)的(de)(de)截(jie)面(mian)(mian)(mian)(mian)(mian)各點相對(dui)于該(gai)截(jie)面(mian)(mian)(mian)(mian)(mian)兩(liang)端點連線(xian)的(de)(de)直線(xian)度(du)偏差(cha)值(zhi)(zhi)折合到(dao)(dao)對(dui)角(jiao)(jiao)(jiao)線(xian)平(ping)(ping)面(mian)(mian)(mian)(mian)(mian)上(shang)，計(ji)(ji)算(suan)(suan)出(chu)相對(dui)于理(li)想(xiang)平(ping)(ping)面(mian)(mian)(mian)(mian)(mian)偏差(cha)。當(dang)按對(dui)角(jiao)(jiao)(jiao)線(xian)原(yuan)(yuan)(yuan)則(ze)評(ping)定(ding)(ding)時，則(ze)取其大(da)偏差(cha)于小(xiao)偏差(cha)的(de)(de)代數(shu)差(cha)為(wei)(wei)所求平(ping)(ping)面(mian)(mian)(mian)(mian)(mian)度(du)誤(wu)差(cha)值(zhi)(zhi);當(dang)按小(xiao)條(tiao)(tiao)件原(yuan)(yuan)(yuan)則(ze)評(ping)定(ding)(ding)時，也可(ke)(ke)計(ji)(ji)算(suan)(suan)出(chu)相對(dui)理(li)想(xiang)平(ping)(ping)面(mian)(mian)(mian)(mian)(mian)的(de)(de)偏差(cha)作為(wei)(wei)對(dui)角(jiao)(jiao)(jiao)線(xian)法(fa)(fa)的(de)(de)原(yuan)(yuan)(yuan)始數(shu)據(ju)(ju)。
