Help needed with spliny toolpath

[randymcdermott]

Hey Guys,

 

I'm trying to get Mastercam to follow the profile of the weld prep on a pipe coupling. My first operation is using a 2" ballnose on a HBM with turntable. The second uses a 6.085" dia. wheel cutter with .5" dia. inserts on a HBM with the coupling clamped to an angle plate.

 

Both toolpaths will produce the shape but the scallops will be unacceptable. I think the wheel cutter is my prefered method for roughing but I would like to follow that with a finishing cut that will follow the shape better ie: a series of 3D splines instead if cutting at a constant Z value.

 

The file can be found at:

 

P.R. Engineering FTP site

 

Use Internet Explorer (not Mozilla 'cause it won't do FTP very well)

 

Any help/suggestions would be greatly appreciated.

 

Randy

I tried your FTP using Explorer didn't work, please advise.

The link doesn't work for me either.

 

Try to copy and paste the following in Internet Explorer.

A further note on my part: The blue cylinder is only used as a check surface. It is on level 2. Make level 2 invisible to see the full part.

the slashs were wrong.

Thanks Jay. I do that.

If I get no answer does that mean it can't be done?

when cutting splines, pay attention to the "Linearization Tolerance". This will affect how faceted the result will be.

Hey Bryan,

 

Thanks for the pointer.
