現有快速原型機有Z軸下降不準確與雷射輪廓掃描不正確問題,為了改善上述問題。本研究目的為開發基於個人電腦之快速原型機,將原有的控制架構,改以精度較高IMP八軸運動控制卡控制雷射掃描系統與鋪成系統,擬訂控制系統硬體及軟體兩大方面進行探討。 1. 硬體部分:首先設計控制系統硬體設備架構 ,然後設計及製作細部的電路,包括電力系統、訊號系統、雷射掃描系統以及鋪層系統。 2.軟體部分:了解 IMP運動控制卡內容,應用Borland C++ Builder6.0內建VCL元件與IMP運動控制函式庫撰寫人機介面程式,以達到INI檔設定、I/0控制、原點復歸、單軸運動控制、自動化流程的功能。 最後實測機台Z軸平台下降與雷射輪廓掃描,Z軸的精度大大的提升,使生胚製作穩定度提高,解決Z軸下降不均問題,並且層厚誤差值已縮至0.09μm以內。並解決 X-Y Table雷射輪廓掃描不正確問題。
The existing Z-axis rapid prototyping machine has decreased inaccurate incorrect contours problems and laser scanning, in order to improve the above problems. The purpose of this study was to develop a PC-based rapid prototyping of the original control structure, high precision IMP changed to eight-axis motion control card controls the laser scanning system and paved the system, to develop the control system hardware and software are two aspects were discussed. 1.Hardware components: First design the control system hardware architecture and circuit design and production details, including power systems, signaling systems, laser scanning systems and shop floor systems. 2.Software components: Learn IMP motion control card content, applications Borland C++ Builder6.0 IMP built VCL components and motion control libraries written HMI programs to achieve the INI profile settings, I/O control, homing, single-axis motion control , automated processes function. Finally, the measured Z-axis machines and laser contour scanning platform dropped precision Z-axis is greatly improved, so that improve raw germ production stability, solve the problem of uneven decline in the Z-axis, and the thickness of the error value has shrunk to less than 0.09μm. And resolve XY Table laser scanning incorrect outline the problem.
