Steep groove in Z-axis

[mathiastveit]

Hi all,

I want to use a flat end mill to machine the grooves on the taper of the part I have attached a picture of.  

I want the endmill to move in Z-axis while X/Y only control the depth of cut. 

Can this be done without using sketch lines and tracing strategy?

Yes, quite easy to do, try the 3D Finishing strategies, I did a crude model for the example just to show one way to do it.

If you have the Model with the grooves already created then try using the "Touch Face" option in the 3D Parallel toolpath.

Just an idea, down to you to use/modify/extrapolate/ignore as you see fit etc, etc 🙂 🙂 🙂

Thanks allot engineguy, that worked nicely. However, I got 10 grooves to machine, meaning that only two of the grooves are aligned to WCS x-axis at 90 and 180 degrees. On these two grooves I got the same result as you, but when selecting the grooves that are at 36 degrees offset from origin the parallel strategy failed. I tried setting up pass direction to 36, 72 degrees etc to no success. 

But got around this issue using patterns. 

Thanks for the help, and a happy new year!

Create a toolpath for one that is acceptable to you. Put it in a Pattern > Rotation and rotate it around the Z axis the appropriate amount of instances, assuming they are equally spaced.

If that doesn't work, could you export and share your Fusion file?

Thanks Seth,

Using patterns was the solution for making all the grooves.
