thanks your reply
i came from Siemens chian MC MTS (SINUMERIK department), i find 840Dsl support ploy programming, but don't how to generate it, customer and enduser ask us, how to do it
i tested it before, but the type is still spline, maybe different type, end user feedback to us, powermill can support poly programming, and 840Dsl also can support poly, so my question is that nx can support it ?
As to my understanding a spline is a poly-line, so the spline output should give you the same output as poly-lines in other software.
I had a discussion with one of the Sinumerik controller developers and you will gain no performance improvement compared to regular G0, G1 and G2/3 programs with the Sinumerik compressor enabled in the controller.
In addition the Sinumerik controller even performs better when you do output G0 and G1, when it comes to switching between G0 and G1, since G0 allows to use a looser tolerance than G1.
So the recommendation was to spend the money on buying the compressor feature of the Sinumerik controller and to output regular G-code with G0/1/2/3 to get best performance.
This is based on using the Sinumerik 840D sl v4.5 or v4.7 controller software.

thanks so much, i definitely understand your means, with the Chinese market development ,there are more and more customer began to do high polish Surface workpiece, so the point to point distance is very very small, even smaller 0.02mm，so the controller processing speed is every challenge, so sorry introduce myself I come from (Siemens SLC MC MTS team (sinumerik department )) , so we want to try to how to increase speed, our controller can compress the programming, but it also occupied resource, if the programming is spline, don't use compressor , we are doing experiment, (Surface quality and speed) , the community is so good, i am a nx hobby, thanks your support my colleague!
