本研究的主要目的是針對「彈性3D成形技術」的數據資料處理軟體部分的進行新功能的配套開發，在維持原軟體功能及效能的同時，增添基於曲棒的曲面熱刮製程規劃及佈料方向相對於成形方向的調整(即佈料頭座向控制)的程序實現。「彈性3D成形技術」的亮點在於可調整的佈料寬度以及沿物件切線方向佈料，藉此提升成型速度。為改善成品表面粗糙度，在佈料製程後增添了熱刮機制進行處理，由於原熱刮棒對於處理複雜曲面存在一定的局限性，故將其從直棒調整為曲棒，並以此為基礎開發其配套軟體進行路徑規劃。同時為實現水平方向上的增厚列印，將五軸機台運動學模型進行轉換改造，以實現佈料頭的座向控制。
針對曲棒熱刮的軟體方面，將現有的資料數據進行重新梳理、提取，通過對原有構型幾何中表面三角形切面數據的捕獲，建立新的資料結構，根據不同的運用場景，開發出三種基於曲棒的模型表面匹配方式，用於優化熱刮路徑，使其盡可能的靠近成品本身曲率，並擴展出在厚切模型下成品表面曲率的優化方式。
在佈料頭座向控制中，根據路徑轉換為控制機台中的控制碼這一過程，建立相應的轉換算法，使佈料頭有更強的適應性及足夠的調整空間，降低其在增厚列印中的干擾，並完成了初步的驗證。

The main purpose of this research is to develop new functions for the geometric data processing software for the Freeform Additive Manufacturing (FAM). The FAM technology features vari-directional material deposition along the tangential directions of part surface which gives surface smoothness and vari-dimensional material deposition according to need of local geometry to increase build rate. In order to achieve good surface finish, material dispensing and a hot scrapping step are applied alternately during the process. The original FAM geometric data processing software has limitations in geometric capability. The hot scrapping process used a straight rod and thus could not produce true curved surfaces efficiently. The dispensing head dispensed erected ribbon-shape material in the same direction as the forming direction and thus is not able to stack multiple ribbons.
In this research, a curved surface hot-scrapping function based on application of a curved hot-scraping bar and an orientation control function for the dispensing head, which adjusts of the dispensing direction relative to the forming direction, were developed.
For the function of hot scrapping by curved bar, three curved bar-based model surface adaptation methods were devised and analyzed to make the scrapped surfaces as close to designed curvature as possible. Based on effectiveness and efficiency, one method was selected and developed and tested by using interference analysis and solid modeling. The application of the method for an improved thick-layer method was further studied.
For the orientation control of the dispensing head, based on the kinematic structure of the FAM’s 5 degree of freedom machine, a corresponding conversion algorithm was established and the data processing program was modified to make the orientation of dispensing head adjustable. The function was verified by basic but actual demonstration on the FAM machine.
