In search of 2.5d finish toolpath

[Anonymous]

I am searching for a 2.5D finish toolpath strategy to handle some difficult cavities and/or parts finishing. I used in past in Wildfire (Creo these days) a volume milling strategy to finish some cavities. Actually that is a roughing strategy but there is a function "scallop control". I put 0.005mm scallop height, leave no material and used just profile only (dont need to cut inside material). It gave me a very nice finish toolpath that was ran only horizontally and take cut by step depth value according to scallop calculation.

I didn't find any thing like this in any software till today.

An example of the parts you are looking to machine would be very helpful in getting you a solution. Can you share anything?

What machines and tooling do you have at your disposal?

Do you have any G-code from your prior software that we could take a peek at and put through a backplotter to see how it managed stock removal?

Hi Seth

Bundle of thanks for reply.

Right now I am checking for collisions on toolpath. After that I will upload the file. I have to go to my previous company to make a toolpath for you so you can check how it works.

By the way I have an old Bridgeport with Heidenhain TNC151. That's why I am interesting to run finish only horizontal like we do roughing.

I am attaching the file. Please check

I had managed to work on a very old system using Wildfire 2. Now you can see in pictures how a roughing strategy finishes the job when we set it to profile only (not rough and profile) and setting wall and bottom scallop height to 0.005 mm.

minimum step depth and scallop height

you can see how the step over and step depth are controlledeven in extreme shallow and steep areasfrom sideside

Ok, I better understand what you are looking for, I think.

No, we do not have a "fixed Z" type of toolpath in Fusion, outside of what 3D Contour offers us. I believe this would be referred to as "Raster" finishing in the product PowerMill, but I may be way off base on that....

This would be a great candidate for Steep and Shallow, but that will not give you compact code that I think you are looking for...

Raster finish = parallal

This is a roughing strategy and we can use it for finish if set leave stock to 0, set profile only property and scallop height to some value. What actually its doing is to ignore step depth and constantly checking for scallop remaining on walls/surfaces and adjust step depth to remove that scallop (cusp). PowerMill is not controlling cusp height effectively. May you people keep this in mind for future features.
