隨著科技和電子技術的日漸進步與發展，傳統機械式凸輪有著易磨損導致精度下降、無法彈性改變凸輪曲線等缺點，逐漸無法滿足當今工業小規模客製化的生產模式，而電子凸輪由於沒有實際主從軸結構所以沒有磨損問題，並且通過簡單的改寫程式便能靈活的更改凸輪運動曲線，大幅降低生產成本，因此在現今工業生產中電子凸輪已漸漸取代傳統凸輪成為主流。本文首先探討電子凸輪的研究背景，藉由已發展成熟的凸輪運動曲線規範來進行電子凸輪曲線軌跡規劃，鑒於規範中的曲線選擇太少，本文額外提出了另外三種曲線分別是多段三次多項式、非均勻有理B樣條曲線及逆向電子凸輪曲線，仿造規範中曲線規劃的步驟進行電子凸輪曲線軌跡規劃，讓使用者有另一種選擇。
然而在曲線規劃的過程中，對於如何得到理想曲線並沒有一個所謂的標準且快速方便的流程，常常得依照使用者的經驗做判斷來回重複修正，導致浪費大量的時間，為此我們將電子凸輪曲線規劃結合最佳化演算法概念，引入粒子群演算法進行最佳化運算，由程式來計算出一條符合要求的最佳曲線，使得使用者不需要再用傳統耗時且依賴使用者經驗的調整辦法，而在粒子群演算法的內部計算規則中，本文額外提出一種新的規則來改良其效果。
之後我們以伺服沖床為例，對沖床中三種模式分別利用規範中的曲線及本文額外提出的三種曲線進行電子凸輪曲線軌跡規劃，再結合粒子群演算法求得各自的最佳曲線軌跡結果，最後根據曲線軌跡結果討論不同曲線的特性及效果。

With the development of science and technology, traditional mechanical cams are gradually replaced by electronic cams due to their shortcomings, such as easy wear and tear, resulting in decreased accuracy and inability to elastically change the cam curve. This thesis discusses the research background of the electronic cam and uses the well-developed cam motion curve standards to plan the trajectories of the electronic cam curves. In view of the fact that there are too few curve choices in the standards, this thesis proposes three kinds of curves, which are multi-segment third-degree polynomials, non-uniform rational B-spline curves, and inverse electronic cam curves.
However, in the process of curve planning, there is no standard, fast and convenient process to obtain the ideal curve. It is often necessary to make judgments based on the user’s experiences and repeated corrections, which results in wasting a lot of time. Therefore, we use the electronic cam curve and combine the concept of optimization algorithm, where the particle swarm optimization for optimization is used to calculate an optimal curve that meets the requirements by the program codes. In the internal calculation rules of particle swarm optimization algorithm, this thesis proposes a new rule to improve its effects.
Finally, we take the servo press as an example and use the curves in the standards as well as the three additional curves proposed in this thesis to plan the trajectories of the electronic cam curves for the three operating modes of the servo press. The characteristics and effects of different curves are discussed based on the results of curve designs.
