Mastercam Generating Wrong Flowline for Surface

[crazy^millman]

Really, just did it in V9

 

Go figure

 

Made several surfaces using ruled and swept, on the exact same geometry, just different chaining techniques and directions....UV lines changed based on that...

 

Did several more using Coons, same result

 

Do you mean X9? :turned:

 

Remember some us do go back to the V7 days and some older.

lol, yeah I did mean X9  

 

and yup,  my lineage goes back to V3.1

Right away. We have an 3Axis CNC so i must cut the piece from the top with a slot mill... In the file are 2 different toolpaths, one using surface contour and the other surface flowline.

Many thanks.

 

I created a flat boundary surface to your contour toolpath and it worked like a champ. Your flowline toolpath looks great. I don't understand why you didn't turn on direction to control the tool getting in and out of the closed shape. If you did that then that would work very well. I have take that same type of toolpath and use material to leave to rough shapes like this. Just copy the toolpath and change your step over and amount of stock to leave and you should be set.

Not true. In earlier versions you were able to manipulate the direction of multiple entities by creating surfaces in the manner in which you wanted the flowline to travel. That ability ended in X8. I used to do this all the time with flowline toolpaths.

 

Still can just like every version before it. Got a sample file showing some problems you have had?

i was able to get surface contour to work.  I used your path.  the only thing i did was make a flat boundary surface on the top to keep it out of the hole and created a gian pacman shaped containment.

 

 

 

i would upload the file but i'm out of space and i only go back to x8

[jlw™]

i also got it to work by adding this revolved surface with no containment.

 

 

by the way your colors suck.  I'd go blind with that.

Thank you very much!!! All of you!!!

 

We are always learnig new stuff someway, and all of you helped me a lot. I'm getting started with this but certainly i'll come back here at the forum put my doubts because i know i'll get them cleared.

 

Best regards!
