【VB+数控原理与系统】数控原理与系统课程设计刀具半径补偿直线-直线VB模拟软件实现

本课题是刀具半径补偿的直线-直线软件实现，是南京工程学院数控专业的数控原理与系统的课程设计，整个工程都是自己随便弄弄的，作为课设作业还算比较严谨吧。题目不难，具体的直线-直线的刀具补偿原理，见机械工业出版社出版的汪木兰主编的《数控原理与系统》的P56~P59，这里不再赘述，具体的代码贴在下边，另外附件中有zip包附带整个工程文件（界面、工程、代码）。具体实现都很简单，因为学期末了，找工作的找工作，考研复试的复试，大多都没兴趣好好弄了，在这里贴上来方便大家交差把。

具体思路稍微一提，对给定的直线的3个点，首先在界面中选择刀补阶段，到底是刀补建立，还是刀补进行，还是刀补撤销，进一步通过直线投影判断两直线夹角，分为伸长型，缩短型，插入型三种情况，分别予以讨论，计算出补偿后的刀具轨迹，然后加以在PICTUREbox中显示。
