Lathe: trochoidal grooving function

Hello,

 

I'm getting back to using NX after about 8 years off and was try to see if NX10 has a lathe trochoidal grooving function. I have used this toolpath on other lowerend CAM softwares and found it very effective. Short of using TEACH or driving a curve I have not found anything, but then again I'm  still finding my around it again.

Thanks in advance.

Re: Lathe: trochoidal grooving function

It can be done with lathe OD roughing, but offhand I don't remember the parameters.

I keep suggesting SPLM get with Sandvik and get an operation template op set up for this, but apparently it falls on deaf ears (maybe I should file an ER?)

Thanks Ken, I will give the OD Rough a go. See what I can make it do.

Hello.

Take a look at the attached file...I mimicked Sandvik Tech guide years ago...

 

Unfortunately...all our requests for Siemens to get with Sandvik & other mfg vendors keep falling on deaf ears...sigh…

 

Please let me know if you have questions related to the toolpath.

 

Kal.

Re: Lathe: trochoidal grooving function

Sandvik has taught 2 methods in the past - teach mode, or using linear zig-zag patttern.

This Sandvik video is for NX6, but the methods can still be used to get paths like these:

Re: Lathe: trochoidal grooving function

I have heard for a couple of years that Volumill is working on a dymanic lathe path but dont know how close it is to being released. Sandvik promotes the dynanic tool paths in almost all HRSA materials using either button tools or the CoroCut full nose radius tools, it is a standard toolpath in many other CAM packages and the lack of it in NX certainly makes it more difficult for customers to implement and consequently lose the benefit of the dynamic tool paths in HRSA materials.
