鑄鐵平板雙軸旋轉法正創小編介紹
雙軸旋轉法是以兩大點連線及兩小點連線為兩根旋轉軸，同時對被測表面各測點的原始數據進行旋轉變換，使大點和點的分布形式符合小條件判別準則之一，進而求得平面度誤差值的一種方法。
由于(yu)(yu)該(gai)法(fa)(fa)(fa)有(you)同時(shi)確(que)(que)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)兩根(gen)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)軸(zhou)(zhou)位(wei)置和(he)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)量(liang)數(shu)值(zhi)，使(shi)數(shu)據變換 簡捷的(de)(de)(de) 點(dian)，所(suo)以平(ping)板(ban)檢(jian)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)規(gui)(gui)程規(gui)(gui)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)采用此(ci)(ci)法(fa)(fa)(fa)。該(gai)法(fa)(fa)(fa)求解的(de)(de)(de)結果，取決(jue)于(yu)(yu)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)軸(zhou)(zhou)和(he)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)量(liang)的(de)(de)(de)確(que)(que)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)，而(er)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)軸(zhou)(zhou)與旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)量(liang)的(de)(de)(de)確(que)(que)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)與大點(dian)、小點(dian)選定(ding)(ding)(ding)(ding)(ding)(ding)(ding)的(de)(de)(de)正(zheng)確(que)(que)性有(you)關。通(tong)常把大點(dian)與小點(dian)稱(cheng)為值(zhi)點(dian)。因此(ci)(ci)如何(he)快速準確(que)(que)地(di)判斷出四(si)上值(zhi)點(dian)，成(cheng)為雙(shuang)軸(zhou)(zhou)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)法(fa)(fa)(fa)的(de)(de)(de)關鍵所(suo)在。按(an)照本書提供(gong)的(de)(de)(de)判定(ding)(ding)(ding)(ding)(ding)(ding)(ding)表(biao)面形(xing)狀、選定(ding)(ding)(ding)(ding)(ding)(ding)(ding)值(zhi)點(dian)、確(que)(que)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)軸(zhou)(zhou)、以此(ci)(ci)例插入法(fa)(fa)(fa)求取旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)量(liang)的(de)(de)(de)方法(fa)(fa)(fa)步驟(zou)，可(ke)使(shi)平(ping)板(ban)檢(jian)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)規(gui)(gui)程規(gui)(gui)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)的(de)(de)(de)雙(shuang)軸(zhou)(zhou)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)法(fa)(fa)(fa)做到(dao)有(you)章(zhang)可(ke)循(xun)， 為實用， 具可(ke)操(cao)作性。
