1、机床数控技术课程设计 机床数控技术课程设计说明书学校：南京航空航天大学专业：机械工程及自动化学号：姓名：设计题目：pl1 dc21指导老师：时间：一课设任务：1.pl1-逐点比较法插补第1象限直线；2.dc21-dda法插补第21象限顺圆弧。二课设要求:1.具有数据输入界面，如输入直线插补的起点、终点，圆弧插补的起止点、圆心或半径、插补的步长等；2.具有插补过程的动态显示功能，如单步插补、连续插补等；3.插补的步长可调；4.直线的起点、圆弧的圆心在坐标系中的位置可变（即直线的起点、圆弧的圆心可不设定在坐标原点）5.建议使用c语言编程，有条件者可使用vb、vc等语言编程。三程序界面及运行截图1.
