数控龙门铣.铣整圆 怎么编程 。要完整的 100圆

如果是在G17面（XY平面），那就可以用G02I-50，或者是G02J-50；如果是在G18面（YZ平面），可以用G02（G03）J-50，或者G02（G03）K-50；如果是在G19面（XZ平面），可以用G02（G03）X-50或者G02（G03）K-50。其中I表示X方向的偏移，J表示Y方向偏移，K表示Z方向偏移。G02（G03）J-50表示：刀具在圆心的Y正方向的圆上，X方向在圆心位置，然后这个程序段表示，刀具会顺时针（逆时针）走一个半径为50的整圆。

数控龙门铣编程怎么编？

在编程时，编程人员必须确定每道工序的切削用量。选择切削用量时，一定要充分考虑影响切削的各种因素，正确的选择切削条件，合理地确定切削用量，可有效地提高机械加工质量和产量。影响切削条件的因素有：机床、工具、刀具及工件的刚性；切削速度、切削深度、切削进给率；工件精度及表面粗糙度；刀具预期寿命及最大生产率；切削液的种类、冷却方式；工件材料的硬度及热处理状况；工件数量；机床的寿命。 ?上述诸因素中以切削速度、切削深度、切削进给率为主要因素。 ?切削速度快慢直接影响切削效率。若切削速度过小，则切削时间会加长，刀具无法发挥其功能；若切削速度太快，虽然可以缩短切削时间，但是刀具容易产生高热，影响刀具的寿命。决定切削速度的因素很多，概括起来有： ?(1)刀具材料。刀具材料不同，允许的最高切削速度也不同。高速钢刀具耐高温切削速度不到50m／min，碳化物刀具耐高温切削速度可达100m／min以上，陶瓷刀具的耐高温切削速度可高达1000m／min。 ?(2)工件材料。工件材料硬度高低会影响刀具切削速度，同一刀具加工硬材料时切削速度应降低，而加工较软材料时，切削速度可以提高。 ?(3)刀具寿命。刀具使用时间(寿命)要求长，则应采用较低的切削速度。反之，可采用较高的切削速度。 ?(4)切削深度与进刀量。切削深度与进刀量大，切削抗力也大，切削热会增加，故切削速度应降低。 ?(5)刀具的形状。刀具的形状、角度的大小、刃口的锋利程度都会影响切削速度的选取。 ?(6)冷却液使用。机床刚性好、精度高可提高切削速度；反之，则需降低切削速度。 ?上述影响切削速度的诸因素中，刀具材质的影响最为主要。 ?切削深度主要受机床刚度的制约，在机床刚度允许的情况下，切削深度应尽可能大，如果不受加工精度的限制，可以使切削深度等于零件的加工余量。这样可以减少走刀次数。 ?主轴转速要根据机床和刀具允许的切削速度来确定。可以用计算法或查表法来选取。 ?进给量f(mm／r)或进给速度F(mm／min)要根据零件的加工精度、表面粗糙度、刀具和工件材料来选。最大进给速度受机床刚度和进给驱动及数控系统的限制。 ?编程员在选取切削用量时，一定要根据机床说明书的要求和刀具耐用度，选择适合机床特点及刀具最佳耐用度的切削用量。当然也可以凭经验，采用类比法去确定切削用量。不管用什么方法选取切削用量，都要保证刀具的耐用度能完成一个零件的加工，或保证刀具耐用度不低于一个工作班次，最小也不能低于半个班次的时间

补充：数控编程是数控加工准备阶段的主要内容之一，通常包括分析零件图样，确定加工工艺过程；计算走刀轨迹，得出刀位数据；编写数控加工程序；制作控制介质；校对程序及首件试切。有手工编程和自动编程两种方法。总之，它是从零件图纸到获得数控加工程序的全过程。
