車銑複合加工機結合車床與銑床加工的特性於一身，可以在同一台加工機上車削加工圓形工件及做銑削平面、鑽孔等加工動作，另外再配合C軸及B軸，使加工形式更多元化，工件由一次挾持便可以直接成形，對於精度的提升有相當大的助益。由於車銑複合加工機為新構型之加工機，國內在車銑複合加工機方面的開發屬剛起步階段，尚有很大的研究發展空間。
　　本論文根據車銑複合加工機的構型，編寫其相對應之MACRO指令，以描繪出工件模型，建立車銑複合加工機的CAD/CAM系統及各種基本運動的路徑插補計算架構。利用所取得加工件各項參數，如尺寸、加工精度等，即可計算工件之加工路徑和切削角度，同時根據車銑複合加工機的機構特性，以逆向運動解為基礎，針對加工路徑插補計算提供各軸控制系統之相對進給數據。

　　The Mill-turn machine tool possesses the features of lathe and miller. It could turn the cylinders, mill the plane and drill hole, etc. To join the C-axis and B-axis, so that it can diversify to work. Because the workpieces are finished direct by one time holding. It has the good precision. Due to Mill-turn machines are new form of machine tool. They are developed recently for domestic industry.
　　This thesis based on Mill-turn Machines form to program the MACRO command. So as to describe the workpiece model, in the end, it would be built about CAD/CAM system and each basic kinematic path interpolating for Mill-turn Machines. According to each parameter from the workpiece, such as dimension, precision etc. then planning the tool path and angle. At the same time, in the tool path interpolation, the cutter-contact (CC) path interpolation theory is used to improve the velocity stability of a machining path. In the inverse kinematics, Denavit-Hartenberg notation is used to analyze the geometry relationships of the Mill-turn mechanism. The theoretical simulations show that the cutter location and the relative driving axes strokes are reasonable and correct.
