本論文的目的主要在提出一套策略，此策略能夠將液動壓拋光系統整合在普遍的CNC工具機上。整合後的CNC工具機可做具有形狀誤差補償能力的液動壓拋光高精度加工。如此一來，就能用便宜的工具機取代昂貴的高精度工具機，並且提升國內CNC工具機的競爭力。

整個策略的規劃包含三個部份：第一，必須先將具有拋光特性的刀具系統硬體，黏附到CNC工具機上；第二，藉由本論文開發的軟體程式，來產生可控制拋光刀具系統和CNC工具機命令；第三，拋光刀具系統必須和CNC工具機能夠達到運動同步；藉由量測CNC工具機的位移資訊，可讓拋光刀具系統以此資訊來配合CNC工具機的位移，做對應的運動。由第一和第三部份可知；此策略並不會破壞整合工具機的結構，而且也不須讀取CNC工具機控制器內部的資訊，所以，整個整合工作的複雜度並不高。

由本論文發展的軟體程式，再配合位移感測器的硬體組裝，刀具系統和工具機的動作就可達到同步，進而可做行形狀誤差補償加工。本論文所發展的程式，只須輸入工件曲面基本資訊和加工參數，就可產生拋光刀具和CNC工具機控制器的命令，不須經過CAM軟體，使用者也不須了解拋光理論，操作上相當容易。此外，整合上所須的CNC工具機，只須x、y、z的三軸運動便可。所以，此策略適用在普遍的CNC工具機上。

The main goal of this thesis is to propose a strategy which can integrate the precision hydrodynamic polishing system with an ordinary CNC machine tool. This integrated CNC machine tool is capable of applying the hydrodynamic polishing process, which is a high-precision machining method, to compensate the form error on a work surface to improve its form precision. With such a compensation capability, a low-cost CNC machine tool may play the function of precision machining as well as an expensive CNC machine tool does. It is hoped that with this function equipped in a CNC machine tool the international competition of the domestic machining industry can be enhanced.

The complete integrating scheme is composed of three parts. The first part is the hardware of polishing system, which is required to attach to the CNC machine tool. The second one is the software developed in this thesis. It includes the codes to generate the commands to control the CNC machine tool and the attached polishing system. The final one is coordinating system that is to synchronize the actions of the CNC machine tool and polishing system. It is done by requiring the polishing system to match the actions of machine tool through measuring the configuration of machine tool consistently. Because of the first and third parts, no modification to the machine tool is needed and the requirement to read the internal information of CNC controller is waved. This will significantly reduce the complexity in implementing the integrating job.

When properly integrated with the required sensors, the software developed in this thesis can harmonize the actions of the polishing system and machine tool to execute the form error compensation task. The software will automatically generate the commands for the polishing system and machine tool based on the geometric and material data of work. It does not require the user to fully comprehend the function of the CAM software and the details of polishing process. This will obviously reduce the skill requirement of operator and facilitate the use of the integrated system. Since the CNC machine tool only plays the function of offering the three translational motions (in X, Y, and Z directions), the application of this strategy to an ordinary CNC machine tool is straightforward.
