cam program control 中文意思是什麼
cam program control
解釋
凸輪程序控制-
Several key techniques of carving and milling machine cnc system are deeply studied they include : the transformation, data rebuild and interface design of huge volume nc program produced by cam ; the algorithm of cubic parametric spline pre _ interpolation and high speed real time interpolation in the cnc system, which. will gain a much higher surface precision and cutting speed ; methodology and algorithm of movement velocity acceleration control on a real time forecast _ and _ prejudge basis is designed. therefore, a smooth movement is insured. the shake and noise problem caused by non _ uniform pules for driving stepping or servo motor is solved by an improving algorithm to generate uniform pules
同時，本文對基於統一的pc平臺的雕銑機數控系統中的幾項關鍵技術進行了深入的研究，包括： cam生成加工程序的傳送、接收、讀取及其加工鏈表的生成和實時重構；對cam生成的離散數據進行三次參數樣條插值和基於累加弦長的三次參數樣條插補控制，保證加工工件表面的精度和光順性；設計具有「前瞻」功能的自動升降速控制方法，保證加工過程的平穩性；通過脈沖均勻化，有效地解決加工過程中因為脈沖不均勻而引起的震動問題。 -
The target is that it begins with the information of the graph ( based on pdm ) used to directly depict parts, being supported by the currency cad / cam system, receiving the producing information by interact with manual, matching the cutter with expert system, building the data of the cutter location ( cl ) by account, finishing the optimising arrangement, creating the nc program for the numerical control system of the fms - ii of sheet metal by the post system, automatically processing the produce by the nc machine tool according to the cl, and then realizing the opening integration of the system of cad / cam system of the fms - ii for sheet metal, basing on pdm
為了解決這些問題，需要重新開發fms -的cad cam系統，目標就是從基於pdm下的通用cad系統提供的圖形信息直接描述零件開始，人工交互方式輸入加工信息，由專家系統的推理機實現自動配模，經計算產生刀位文件，優化排料后，再針對鈑金fms -的數控系統，後置處理生成相應的數控加工程序，數控機床根據加工程序代碼自動完成加工，從而實現鈑金fms -的cad cam系統基於pdm下的開放集成。
