数控编程与操作
数控编程与操作
作业1
1.什么叫数控和数控编程？
答：
数控（数字控制）：
是用数字指令来控制机床的动作。
数控机床：
装备了数控系统的机床。
2.数控机床的适用场合是什么？
答：
1.多品种小批量生产2.几何形状复杂的零件3.需要频繁改型的零件4.贵重的不允许报废的零件5.需要严格控制公差的零件
3.数控机床由哪几部分组成？
答：
由程序载体、输入装置、数控装置、伺服系统、反馈装置和机床组成。
4.数控机床按运动方式和按伺服系统控制方式分别分为哪几类？
答：
（一）按运动控制方式分
（二）按伺服系统分
1.点位控制数控机床1.开环控制数控系统
2.直线控制数控机床2.闭环控制数控系统
3.轮廓控制数控机床3.半闭环控制数控系统
作业2
5.零件装夹的原则是什么？
答：
（1）应尽量减少装夹的次数，力争一次装夹后能加工出全部待加工面
（2）如需要二次装夹时，要尽可能利用同一基准面以减少加工误差
6.在安排加工程序时应注意什么？
答：
1.先粗后精2.先主后次3.先基准后其他4.尽量减少换刀次数
7.在确定加工路线时应遵循什么要求？
答：
1.保证工件的加工精度和表面粗糙度2.尽量缩短加工路线减少刀具空行程时间3.使数值计算简单，程序段数少
作业3
8.什么叫基点？
答：
构成工件轮廓的不同几何素线的交点或切点称为基点。
9.什么叫手工编程？
手工编程有什么特点？
答：
手工编程是利用规定的代码和格式，人工制定工件加工程序的工作。
手工编程的特点：
1.对加工形状简单的工件，编程比较快捷简便2.不需要具有特别的条件3.不适合编制形状复杂的工件。
10.手工编程的步骤有哪些？
答：
零件图样—确定工艺过程—计算加工轨迹尺寸—编写加工程序—校核—输入机床—校验试切削—完成
11.常见的工艺文件有哪些？
答：
加工工序卡、数控刀具调整单、机床调整单、零件加工程序单等。
