前言
一個程序適用N種產品,該如何進行編程?
在測量應用中,對于相似產品,如:環規,想要提高測量效率,并且減少產品程序的數量,測量員可以對產品的相同點進行一定分析,發現其中部分數據可實現參數化,通過RationalDMIS軟件的高級語言功能實現產品的快速測量,并適用于多種規格的產品。
1、產品分析
對于有著眾多規格的環規而言,如果每一個規格的大小都進行編程,是一個非常繁瑣且不便的工程,對于測量員使用對應程序也是極其不便的,影響測量效率。我們對環規這類產品進行分析,特點如下圖:
環規的類型內外為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,環規直徑定義為DM,測量截面數量m,每個截面測量點數為n。
2、程序的設計
2.1 程序運行后,通過人為輸入,可以實現不同規格產品的自動測量
2.2 流程圖
2.3 RationalDMIS 程序編寫
(1)通過DMIS提示,設置一個運行時輸入參數的提示窗口
代碼如下:
(2) 對參數進行判斷,如判斷環規類型、輸入內容為字母、0 等情況
(3)手動建立坐標系
(4)設置安全平面宏
(請將安全平面宏程序按以下內容修改)
(5)自動精建坐標系
(6)評價與分析
通過前面輸入的層數與點數參數,進行圓柱測量,并進行評價
(7)生產檢測報告
(8)總結
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,判斷規格類型;
2、利用賦值,將管控參數賦給變量;
3、通過變量,規劃測量軌跡,實現了不同規格的產品的檢測;
最終實現一個程序,完成N個不同規格產品的自定、高效測量。
(9)完整代碼如下
