現今的金屬類精密切削加工技術領域中常用多軸綜合加工機(例如五軸加工機)執行加工程序，而為了符合產品高精密度的要求，其加工過程必須嚴格控制各項參數，包含工具機精密度、工具機熱變形、刀具精密度、進給速度與振動等參數。其中，被加工的產品本身也有多種因素導致加工變形，例如材質及產品形狀、夾持裝置的壓力等。特別是，應用在航太用的渦扇發動機的大型外殼板件(曲形板件)，採用鈦合金材質精密加工而成，其進行加工時非常容易發生上述加工變形。In today's metal precision cutting technology field, multi-axis comprehensive processing machines (such as five-axis processing machines) are commonly used to execute processing procedures. In order to meet the requirements of high precision products, the processing process must strictly control various parameters, including machine tools. Parameters such as precision, thermal deformation of the machine tool, tool precision, feed rate and vibration. Among them, the processed product itself also has many factors that cause processing deformation, such as material and product shape, the pressure of the clamping device and so on. In particular, the large shell plates (curved plates) of turbofan engines used in aerospace are precisely machined from titanium alloys, and the above-mentioned machining deformations are very likely to occur during machining.
