24、 12立铣刀一把，6麻花钻一根。三、相关知识概述数控铣床的主要加工对象为平面类零件、箱体类零件和曲面类零件。如果换上孔加工刀具，还能进行数控钻、镗、锪、铰及攻螺纹等孔加工操作。由于数控铣床没有刀具库，不具有自动换刀功能，所以其加工程序的编制比较简单；通常数值计算量不大的平面轮廓加工程序或孔加工程序可直接通过手工编程完成。编程时选择合适的坐标位置编程方式可使程序简化，减少数值计算工作量。坐标位置编程方式有绝对指令方式和相对指令方式两种，主要根据图纸上尺寸的标注方式来选择。当加工尺寸由一个固定基准给定时，采用绝对指令方式编程较为方便。当加工尺寸是以轮廓o顶点之间的间距给出时，采用相对指令方式编程较

25、为方便。(1)绝对值编程指令(G90)和相对值编程指令(G91)。格式：式中，G90为绝对值编程指令，每个坐标轴上的编程值是相对于程序原点的；G91为相对值编程指令，每个坐标轴上的编程值是相对于前一位置而言的，该值等于沿坐标轴移动的距离。G90、G91为模态功能指令，G90为缺省值。 (2)固定循环指令(G98，G99)固定循环指令的程序格式包括数据形式、返回点平面、孔加工方式、孔位置数据、孔加工数据和循环次数。数据形式(G90或G91)，在程序开始时就已指定，因此，在固定循环指令的程序格式中可不注出。格式 图61 G73指令动作图 图62 G74指令动作图式中，第一个G代码(G98或者G99

26、)为返回点平面G代码，G98为返回初始平面，G99为返回R点平面；第二个G代码为孔加工方式，即固定循环代码G73(高速深孔加工指令)，G74，G76和G81G89中的任一个(G73、G74指令动作图，如图6l、图62所示)；X、Y为孔位数据，指被加工孔的坐标位置；Z为R点到孔底的距离(G9l时)或孔底坐标(G90时)；R为初始点到R点的距离(G91时)或R点的坐标值(G90时)；Q为每次进给深度(G73或G83时)，增量值，Q0；I、J为刀尖向反方向的移动量(分别在X、y轴向上)；P为刀具在孔底的暂停时间；F为刀具切削进给速度；L为固定循环的次数。四、实验内容 (1)根据数控系统的程序格式，编

27、制如图1-1所示零件的加工程序。图1-1 加工零件图 (2)根据上述加工零件制定加工工艺。 1)工艺分析技术要求本实验加工零件的毛坯如图1-2所示，毛坯的大平面经过预先铣削加工，材料为石蜡。图1-2 零件毛坯图加工工艺的确定加工方式：由零件图和毛坯图可知，该零件需要进行铣削和钻削加工。装夹定位的确定：为了在一次装夹后完成所有的加工，所准备的毛坯增加了一个工艺厚度，可以利用它将其装夹在乎口钳上，在加工完零件形状后再设法去除。 加工刀具的确定，平铣刀(12、6)各1把，麻花钻(16)一把。切削用量：主轴转速300rmin，进给速度150mmmin。、2)数学计算。建立工件坐标系。根据零件图中的尺寸

28、标注，程序中有些基点的绝对坐标位置可直接读出，另外些基点间的相对位置也可直接读出，所以在编程时可用绝对坐标位置和相对坐标位置这两种坐标值方式。 3）加工结果，如图1-3：图1-3 零件加工完成图4）程序%O0000(MACHINE_GROUP_1)(DATE=DD-MM-YY - 12-11-13 TIME=HH:MM - 18:27)(MCX FILE - C:USERSLENOVODESKTOP3.MCX-5)(NC FILE - C:USERSLENOVODESKTOPMACHINE_GROUP_1.NC)(MATERIAL - ALUMINUM MM - 2024)( T1 | 12.
