數控工具機刀具半徑補正之研究與分析

Abstract

本篇論文最主要的參考資料為Fanuc工具機操作手冊，首先對手冊中基本程式指令功能做了解，接下來對其補償功能的指令做深入的探討。

其研究的目的在於推導電腦數值控制工具機的刀具半徑補正演算法，並將推導完成的數學公式以C語言實現之。為了驗證所推導的公式是否正確，利用AutoCAD軟體根據幾何關係建立不同型態的測試圖檔，將其在AutoCAD軟體裡所量測到的未補正座標輸入C語言所撰寫的程式，若程式所得到的輸出座標與AutoCAD軟體量測所得到的補正座標不符，則修改刀具半徑補正演算法與程式，直到兩者結果相符為止，方可得到正確的刀具半徑補正演算法。

若藉由本論文所發展的刀具半徑補正機制，則程式設計者只須依工件的實際尺寸編寫工具機程式，將可避免編寫程式時的許多困擾。

The main reference of this thesis is Fanuc machine manual. First of all, I studied the basic program commands in the manual, and then investigated the commands of compensation in depth.

The purpose of this research is to derive the cutter radius compensation algorithm of computer numerical control machine and implement the derivational mathematics formula by C programming language. In order to test and verify if these formulas are correct, I made use of AutoCAD according to geometry to make different types of pattern, and input the uncompensated coordinates to C Programming language. If the output coordinates obtained from the program disagree with the compensated coordinates from AutoCAD, I have to modify the cutter radius compensation algorithm and my program until they correspond with each other. And then I got the correct cutter radius compensation algorithm.

If to rely on the cutter radius compensation function in this thesis, the programmers can compile the machine programs depending on geometric real size of workpieces and then diminish the mistakes when compiling program.
