前言
一個程序適用N種產(chǎn)品,該如何進(jìn)行編程?
在測量應(yīng)用中,對于相似產(chǎn)品,如:環(huán)規(guī),想要提高測量效率,并且減少產(chǎn)品程序的數(shù)量,測量員可以對產(chǎn)品的相同點(diǎn)進(jìn)行一定分析,發(fā)現(xiàn)其中部分?jǐn)?shù)據(jù)可實(shí)現(xiàn)參數(shù)化,通過RationalDMIS軟件的高級語言功能實(shí)現(xiàn)產(chǎn)品的快速測量,并適用于多種規(guī)格的產(chǎn)品。
1、產(chǎn)品分析
對于有著眾多規(guī)格的環(huán)規(guī)而言,如果每一個規(guī)格的大小都進(jìn)行編程,是一個非常繁瑣且不便的工程,對于測量員使用對應(yīng)程序也是極其不便的,影響測量效率。我們對環(huán)規(guī)這類產(chǎn)品進(jìn)行分析,特點(diǎn)如下圖:
環(huán)規(guī)的類型內(nèi)外為TYPE,總高度定義為H,頂部向下偏移量定義為UP,底部向上偏移量定義為DP,環(huán)規(guī)直徑定義為DM,測量截面數(shù)量m,每個截面測量點(diǎn)數(shù)為n。
2、程序的設(shè)計(jì)
2.1 程序運(yùn)行后,通過人為輸入,可以實(shí)現(xiàn)不同規(guī)格產(chǎn)品的自動測量
2.2 流程圖
2.3 RationalDMIS 程序編寫
(1)通過DMIS提示,設(shè)置一個運(yùn)行時輸入?yún)?shù)的提示窗口
代碼如下:
(2) 對參數(shù)進(jìn)行判斷,如判斷環(huán)規(guī)類型、輸入內(nèi)容為字母、0 等情況
(3)手動建立坐標(biāo)系
(4)設(shè)置安全平面宏
(請將安全平面宏程序按以下內(nèi)容修改)
(5)自動精建坐標(biāo)系
(6)評價與分析
通過前面輸入的層數(shù)與點(diǎn)數(shù)參數(shù),進(jìn)行圓柱測量,并進(jìn)行評價
(7)生產(chǎn)檢測報告
(8)總結(jié)
通過RationalDMIS軟件,只需簡單3步,即可完成:
1、條件判斷,輸入管控參數(shù),判斷規(guī)格類型;
2、利用賦值,將管控參數(shù)賦給變量;
3、通過變量,規(guī)劃測量軌跡,實(shí)現(xiàn)了不同規(guī)格的產(chǎn)品的檢測;
最終實(shí)現(xiàn)一個程序,完成N個不同規(guī)格產(chǎn)品的自定、高效測量。
