碩士 === 國立臺北科技大學 === 自動化科技研究所 === 93 === In this study, we use ADSP-2183 DSP device (developed by Analog Devices company) as the tool, from the kinematic point of view, an motion control card embedded with several velocity profiles is developed. These velocity profiles include Trapezoidal, 2nd order s curve, 4th order s curve and cycloidal curve. Depending on the reguirements, we can choose one of these velocity profiles to finish a stable and fast precision motion .Combined with VBA language for AutoCAD and DLL function written by visual C++, thru the motion control card, we can directly control the XYZ table from the AutoCAD screen.The experimental results can also be feedback and shown on the screen. By comparing the results for different velocity profile, the cycloidal curve shows it has better smooth and stable motion than other curves. For this reason an motion control card embedded with modified cycloidal curve is suitable for use in the movement of XYZ Table. The use of AutoCAD interface platform in the control of xyz Table also shorten the time between the desigining and machining.
