專利名稱：二維編程軟件編制tbm刀盤三維輪廓加工的方法
技術領域：
本發明涉及一種三維輪廓的加工方法，尤其是一種二維編程軟件編制TBM刀盤三維輪廓加工的方法。
背景技術：
現在一般進行三維輪廓的加工，需要購買專門的三維編程軟件，同時還需要編程軟件在軌跡設置過程中刀具能夠滿足圖紙中的傾斜角度，并且在加工過程中還要花費大量的加工時間，這樣既花費大量財力，也耗費時間。
發明內容
針對上述現有技術的不足，本發明提供了一種用二維編程軟件，使用TBM刀盤加工三維輪廓的方法。
為實現上述目的，本發明采用的技術方案是二維編程軟件編制TBM刀盤三維輪廓加工的方法，將萬用角銑頭上所安裝的刀具的底平面垂直于三維輪廓中底平面，利用數控編程軟件中的二維編程的坐標系偏移及旋轉功能實現三維輪廓中的變化較大的平面內的輪廓的編制工作，然后再利用改變零件加工深度的辦法來實現三維輪廓的加工。
如果利用三維編程軟件編制三維數控加工程序加工三維輪廓，需要花費巨大的財力去購買三維數控編程軟件，因此當偶爾遇到三維輪廓的加工時就可以利用本發明的方法來完成三維輪廓的加工了，這樣既節約費用，又節省時間。
圖1是實施例1中根據原始坐標系建立三維輪廓圖。
圖2是實施例1中利用原始坐標系使進行坐標系偏移。
圖片3是實施例1中在對已偏移的坐標系進行旋轉。
圖4是萬用角銑頭刀具的主視圖。
圖5是圖4的左視圖。
具體實施例方式本發明所使用的設備的型號為PF-H-100KW(IS)375/350/700(600)數控龍們銑床機床的主要規格為；立柱之間的寬度3750主軸端面至工作臺面的距離為3500，工作臺規格(寬*長)3250*13700，最大工件重量為200噸主軸錐孔60(724)，工作臺行程(X軸)14503，銑頭橫向行程(Y軸)4650，滑枕垂直行程(Z軸)1250，橫梁垂直行程(W軸)3000。
本機床所用的數控系統為西門子840C。
實施例1如圖1所示，首先根據工件的實際情況在編程軟件的原始坐標系下建立三維輪廓部分的立體圖形。
如圖2所示，然后將編程軟件中原始坐標系進行偏移，偏移位置為三維輪廓的中心。
如圖3所示，最后對已經偏移的坐標系進行旋轉，使旋轉后的坐標系的各Z軸垂直于所畫的三維圖形的上平面而其余兩軸則平行于有規律的另兩面。
如圖4和圖5所示，二維圖畫好以后，利用數控后置生成程序過程中的切削深度的辦法將垂直于已畫好的二維輪廓的底面的距離確定，這樣在生成數控程序的時候，由于編程軟件所產生的機床數據都是相對于軟件原始坐標系的平行坐標系確定的，所以經過偏移并旋轉的輪廓的位置就是相對于原始坐標系的數控程序還不能直接拿到數控機床進行加工。因為它不是三維加工程序，而必須通過機床附件的協助還原我們在畫圖過程中旋轉的過程，即使刀具垂直于三維輪廓的低平面，這樣就可以利用我們剛剛編制好的程序來加工三維輪廓了。

全文摘要
二維編程軟件編制TBM刀盤三維輪廓加工的方法，將萬用角銑頭上所安裝的刀具的底平面垂直于三維輪廓的底平面，利用數控編程軟件中的二維編程的坐標系偏移及旋轉功能實現三維輪廓中的變化較大的平面內的輪廓的編制工作，然后再利用改變零件加工深度的辦法來實現三維輪廓的加工。如果利用三維編程軟件編制三維數控加工程序加工三維輪廓，需要花費巨大的財力去購買三維數控編程軟件，同時用三維編程方法編制的加工程序在加工過程中還要花費大量的時間，因此當偶爾遇到三維輪廓的加工時就可以利用本發明的方法來完成三維輪廓的加工了，這樣既節約費用，又節省時間。
