機床的剛性與床身鑄件的成分及床身鑄件結構、數控機床鑄件鑄造工藝、床身鑄件的加工工藝的多個因素有關系。在設計環節，通過機床動力學，對床身鑄件進行受理分析。
要(yao)使(shi)床(chuang)身鑄件的度誤差小，的加工對床(chuang)身鑄件的度起著(zhu)決(jue)定性的作用(yong)
床(chuang)身(shen)(shen)鑄(zhu)件(jian)(jian)尺(chi)(chi)(chi)度(du)(du)公役(yi)是指鑄(zhu)件(jian)(jian)公役(yi)尺(chi)(chi)(chi)度(du)(du)的(de)兩(liang)個答應限(xian)尺(chi)(chi)(chi)度(du)(du)之差。在這個答應限(xian)尺(chi)(chi)(chi)度(du)(du)之內床(chuang)身(shen)(shen)鑄(zhu)件(jian)(jian)可滿意加(jia)工、安裝和(he)運用的(de)需(xu)(xu)求。床(chuang)身(shen)(shen)鑄(zhu)件(jian)(jian)的(de)尺(chi)(chi)(chi)度(du)(du)度(du)(du)取決于技術(shu)規劃及技術(shu)過程操控(kong)的(de)嚴(yan)厲(li)程度(du)(du)，鑄(zhu)件(jian)(jian)尺(chi)(chi)(chi)度(du)(du)度(du)(du)需(xu)(xu)求越(yue)高，對(dui)要(yao)素(su)的(de)操控(kong)應越(yue)嚴(yan)厲(li)，鑄(zhu)件(jian)(jian)出產成(cheng)本(ben)相(xiang)應地也要(yao)有所(suo)提高。有科(ke)學的(de)規范來和(he)諧(xie)供、需(xu)(xu)兩(liang)邊的(de)需(xu)(xu)求。
中國 規(gui)范(fan)《床(chuang)身鑄(zhu)件(jian)(jian)(jian)(jian)尺(chi)(chi)(chi)度(du)(du)公(gong)(gong)(gong)役(yi)》（GB6414—1999）等(deng)效選用(yong)ISO8062—1994二版《鑄(zhu)件(jian)(jian)(jian)(jian)尺(chi)(chi)(chi)度(du)(du)公(gong)(gong)(gong)役(yi)制》。它是規(gui)劃和(he)檢驗(yan)件(jian)(jian)(jian)(jian)尺(chi)(chi)(chi)度(du)(du)的依據(ju)，具體規(gui)則了砂型鍛(duan)(duan)造(zao)(zao)、金屬型鍛(duan)(duan)造(zao)(zao)、低(di)壓鍛(duan)(duan)造(zao)(zao)、壓力鍛(duan)(duan)造(zao)(zao)、熔(rong)模鍛(duan)(duan)造(zao)(zao)等(deng)辦法出產的各種鍛(duan)(duan)造(zao)(zao)金屬及合金的機床(chuang)鑄(zhu)件(jian)(jian)(jian)(jian)尺(chi)(chi)(chi)度(du)(du)公(gong)(gong)(gong)役(yi)，包(bao)含鑄(zhu)件(jian)(jian)(jian)(jian)根本(ben)尺(chi)(chi)(chi)度(du)(du)公(gong)(gong)(gong)役(yi)值(zhi)，所規(gui)則的公(gong)(gong)(gong)役(yi)是指正(zheng)常出產條件(jian)(jian)(jian)(jian)下(xia)通常能到(dao)(dao)達的公(gong)(gong)(gong)役(yi)，由到(dao)(dao)粗分(fen)為16級，命名(ming)為CT1~CT16。床(chuang)身鑄(zhu)件(jian)(jian)(jian)(jian)尺(chi)(chi)(chi)度(du)(du)公(gong)(gong)(gong)役(yi)等(deng)級比(bi)列系數(shu)：CT3~CT13，選用(yong)√2；CT13~CT16，選用(yong)3√2 。床(chuang)身鑄(zhu)件(jian)(jian)(jian)(jian)根本(ben)尺(chi)(chi)(chi)度(du)(du)即鑄(zhu)件(jian)(jian)(jian)(jian)圖(tu)上(shang)給定的尺(chi)(chi)(chi)度(du)(du)，應(ying)包(bao)含機械加工余量。公(gong)(gong)(gong)役(yi)帶應(ying)對(dui)稱分(fen)布(bu)。有 殊需(xu)求時(shi)，也可非對(dui)稱布(bu)置，并應(ying)在圖(tu)樣(yang)上(shang)注明或技術文件(jian)(jian)(jian)(jian)中規(gui)則。
壁(bi)厚(hou)尺(chi)度(du)差通常(chang)可降低(di)，例如，圖樣上通常(chang)尺(chi)度(du)公役(yi)為CT10級，則(ze)壁(bi)厚(hou)尺(chi)度(du)公役(yi)為CT11級。在圖樣上選用公役(yi)等級代(dai)號(hao)標示，如GB6411—CT10。當(dang)要約束錯(cuo)箱值為，應標出大錯(cuo)箱值。如GB/T6411—1999—大錯(cuo)箱值1.0。
床身(shen)(shen)鑄件鑄造(zao)(zao)生產經常要(yao)用(yong)的材(cai)料(liao)有各種(zhong)金屬、焦炭、木(mu)材(cai)、塑料(liao)、氣體和(he)液(ye)體燃料(liao)、造(zao)(zao)型材(cai)料(liao)等。所需設備有冶煉金屬用(yong)的各種(zhong)爐子，有混(hun)砂(sha)用(yong)的各種(zhong)混(hun)砂(sha)機(ji)(ji)(ji)，有造(zao)(zao)型造(zao)(zao)芯(xin)用(yong)的各種(zhong)造(zao)(zao)型機(ji)(ji)(ji)、造(zao)(zao)芯(xin)機(ji)(ji)(ji)，有清理床身(shen)(shen)鑄件用(yong)的落砂(sha)機(ji)(ji)(ji)、拋丸機(ji)(ji)(ji)等。還有供 種(zhong)鑄造(zao)(zao)用(yong)的機(ji)(ji)(ji)器(qi)和(he)設備以及許多運輸和(he)物料(liao)處理的設備。
