3D Surface Roughing assistance

[ThickChips]

Hi all,

I have a part that is quite large and requires some  3Axis 3D surface roughing. The surfaces are just "angled" surfaces although, one surface is curved. I've attached a test file that is similar to my application.

My strategy is to hopefully use a HF mill to rough this profile from a square block. Then finish with endmills or other tools. But I'm struggling where to begin. 

I do not believe we have a 3D package, as I tried running a 3D "Parallel" toolpath and get the error. However, 3D Optirough allows me to use it, only without avoidance stock I think?

Nevertheless, in the past, I've converted surfaces to 3D WF and have done contours that way but it's cumbersome and very non-dynamic.

My first question would be, could someone check out my file and see what I'm working with? Any tips would help. If we have to upgrade, then so be it. 

 

Thanks for any help you can offer.

A few things before diving to deep.

In your tool definition, increase the Cutting length to include the top rad. I bumped it up to .125".

In optirough cut Parameters the 100% stepdown = 1x tool diameter. Change this to manufacturer recommendations for depth of cut,

The Step over distance can be bumped up to 70 to 80 %

I made 3 options:

1st - Area roughing - For High Feed cutters I prefer over OptiRough,

2nd - Classic Rough Parallel. It's not ideal - leaving big steps that needed to be removed.

3rd - Classic Rough Pocket.

For High Feed cutter you cannot drop your tool down like solid carbide.

I used .040" down and 70% stepover, change it to SECO catalog suggestion.

What material?

Hello all

 

Thanks for your help with this.

@OVodov This is an excellent starting point for me to tweak. However, I notice our package does not work with any of those three toolpath types. We will have to upgrade!
