本文旨在使擺動圓柱凸輪驅動鍛壓肘節機構，應用於連續鍛壓運動機構的相關產業自動化設備中。首先，透過擺動圓柱凸輪輸入軸與其從動件之運動曲線函數關係，利用剛體轉置法進行凸輪幾何設計與分析，確認圓柱凸輪之機械特性，接著由凸輪機構從動件輸出軸作為驅動鍛壓肘節驅動桿件，利用向量解析法，求取肘節機構桿件和接頭的運動，即得裁模的運動情形。
本機構作動目的為提供裁模提供足夠之裁切力，由裁模作動所需裁切力，分析驅動肘節機構所需驅動力及各支座所需承受之支座反力，進而推算圓柱凸輪與其從動件的傳遞力，得到驅動圓柱凸圓輸入軸的所需動力。
最後針對裁模作動與拖紙機構負載的關係，利用有理式B仿線調整裁模運動位置時序規劃，並調整圓柱凸輪半徑、擺角初值、擺臂長度等參數設計分析，以降低所需輸入動力，以求得高速且重負載運動特性驅動鍛壓肘節機構。

A toggle cutting mechanisms driven by cylindrical cam is presented, which is used in automatic die-cutting machine. First of all, to synthesize the follower motion curves of cylindrical cam, based on the rigid body transformation, the cam profiles and the properties of the cam mechanisms can be determined. In addition, the toggle cutting mechanisms is driven by the follower of cylindrical cam. Based on the vector operation, the motion of links and pins are analyzed. That is kinematics analysis of toggle cutting mechanisms.
Since the main function of this mechanism is to provide working cutting force, from analyzing the driving force of toggle mechanism and each bearing reaction forces, based on to the cutting force from cutting action, the transmission forces between cylindrical cam and its follower is calculated and the power required by this mechanism is determined.
Furthermore, refer to the load of cardboard conveyor, through applying the rational B-splines to tune time sequence of the toggle cutting mechanisms and using different design parameters, such as the radius of the cylindrical cam, initial angle of follower and arm of follower, the power required of this mechanism is reducing and the high working speed and load toggle cutting mechanisms are investigated.
