Machining center operating procedures

  加工中心操作规程
  基本事项
  1、进入车间实习时,要穿好工作服,大袖口要扎紧,衬衫要系入裤内。女同学要戴安全帽,并将发辫纳入帽内。不得穿凉鞋、拖鞋、高跟鞋、背心、裙子和戴围巾进入车间。注意:不允许戴手套操作机床;
  2、注意不要移动或损坏安装在机床上的警告标牌;
  3、注意不要在机床周围放置障碍物,工作空间应足够大;
  4、某一项工作如需要俩人或多人共同完成时,应注意相互间的协调一致;
  5、不允许采用压缩空气清洗机床、电气柜及NC单元;
  6、应在指定的机床和计算机上进行实习。未经允许,其它机床设备、工具或电器开关等均不得乱动;
  准备事项
  1、操作前必须熟悉数控铣床的一般性能、结构、传动原理及控制程序,掌握各操作按钮、指示灯的功能及操作程序。在弄懂整个操作过程前,不要进行机床的操作和调节。
  2、开动机床前,要检查机床电气控制系统是否正常,润滑系统是否畅通、油质是否良好,并按规定要求加足润滑油,各操作手柄是否正确,工件、夹具及刀具是否已夹持牢固,检查冷却液是否充足,然后开慢车空转3~5分钟,检查各传动部件是否正常,确认无故障后,才可正常使用。
  3、程序调试完成后,必须经指导老师同意方可按步骤操作,不允许跳步骤执行。未经指导老师许可,擅自操作或违章操作,成绩作零分处理,造成事故者,按相关规定处分并赔偿相应损失
  4、加工零件前,必须严格检查机床原点、刀具数据是否正常并进行无切削轨迹仿真运行。
  过程注意事项
  1、加工零件时,必须关上防护门,不准把头、手抻入防护门内,加工过程中不允许打开防护门;
  2、加工过程中,操作者不得擅自离开机床,应保持思想高度集中,观察机床的运行状态。若发生不正常现象或事故时,应立即终止程序运行,切断电源并及时报告指导老师,不得进行其它操作;
  3、严禁用力拍打控制面板、触摸显示屏。严禁敲击工作台、分度头、夹具和导轨;
  4、严禁私自打开数控系统控制柜进行观看和触摸;
  5、操作人员不得随意更改机床内部参数。实习学生不得调用、修改其它非自己所编的程序;
  6、机床控制微机上,除进行程序操作和传输及程序拷贝外,不允许作其它操作;
  7、数控铣床属于大精设备,除工作台上安放工装和工件外,机床上严禁堆放任何工、夹、刃、量具、工件和其它杂物;
  8、禁止用手接触刀尖和铁屑,铁屑必须要用铁钩子或毛刷来清理;
  9、禁止用手或其它任何方式接触正在旋转的主轴、工件或其它运动部位;
  10、禁止加工过程中测量工件、手动变速,更不能用棉丝擦拭工件、也不能清扫机床;
  11、禁止进行尝试性操作;
  12、使用手轮或快速移动方式移动各轴位置时,一定要看清机床X、Y、Z轴各方向“、-”号标牌后再移动。移动时先慢转手轮观察机床移动方向无误后方可加快移动速度;
  13、在程序运行中须暂停测量工件尺寸时,要待机床完全停止、主轴停转后方可进行测量,以免发生人身事故;
  14、机床若数天不使用,则每隔一天应对NC及CRT部分通电2-3小时。
  15、关机时,要等主轴停转3分钟后方可关机。
