标题: 【求助】cimatron nc parameter [打印本页] 作者: cimatron 时间: 2002-4-9 22:33 标题: 【求助】cimatron nc parameter HELP ME!!
I have met some problem at my work.Please help me.
I operate a CNC machine with SIMENS(802s) system.And I use CIMATRON for CAM.But I don't know how to modify the post for SIMENS system.
The other problems are:
1. What's the difference between STOCK SPIRAL and SPIRAL CUT way?
2.What's the difference OPEN PART:NO/OPEN PART:OUTER ONLY/ OPEN PART: OUTER+ISLAND ?
3.In the STOCK SPIRAL way, what's means of REGION COLLAPSING/SPIRAL COLLAPSING?
And what's the difference between REGION COLLAPSING/SPIRAL COLLAPSING and MACHINING:BY REGION / MACHINING:BY LAYER?
4.What's means and what's the difference between APPROX BY TOL./APPROX BY TOL.+LENGTH? And does CIMATRON use triangle to approximate surface?
5.What's means of APPORX DEFINE / APPORX IGNOR(USE) / CHK.GEMO.STAT in the TP.MNGR?
{attached GB chinese version:
我将使用的机床用的是西门子802S系统，不知后处理（。EXF)如何修改？听说要全模块的CIMATRON才行，不知是否？
另
1。切削方式STOCK SPIRAL / SPIRAL CUT 有何区别？
2。OPEN PART:NO/OPEN PART:OUTER ONLY/ OPEN PART: OUTER+ISLAND 区别如何？
3。在STOCK SPIRAL 切削方式下，REGION COLLAPSING/SPIRAL COLLAPSING含义如何？ 和 MACHINING:BY REGION / MACHINING:BY LAYER区别如何？
4。APPROX BY TOL./APPROX BY TOL.+LENGTH区别如何?CIMATRON中是用三角形逼近曲面的
吗？
5。在TP.MNGR 的管理界面中，APPORX DEFINE / APPORX IGNOR(USE) / CHK.GEMO.STAT 三个参数的作用如何？
请各位多多指教！

很多问题你自己做过例子，再改些参数就能看出区别来。
OPEN PART: NO/OPEN
OUTER ONLY
OUTER+ISLAND
在一个毛坯里，cimatron可以通过此选项决定下位置和刀路的限定范围。
NO/OPEN 不在选定的轮廓外面进刀，所有刀路也在轮廓内。
OUTER ONLY 可在轮廓外下刀，加工凸模类的零件适用，避免直接在毛坯里落刀。
OUTER+ISLAND 如果毛坏中心有孔，它会自动在孔内和毛坯外落刀。
这些功能只是增加了手动控制刀具能否进入这些位置的选项，适合特殊情况时，关闭这些功能。
