REST MILL

[Pgreenlaw]

I have a part that has been challenging me with my programming skills from start to finish. I am almost complete with the program and looking for any advice on finishing/continuing the inside .062 rads down the corner of this "ramp". I finish the majority of the ramp surface with a .375 ball end mill using a scallop tool path. I will have to finish with a long-reach reduced shank (1.5") .125 ball end mill. I have played with a few toolpaths but am not getting results I am happy with. Any help or suggestions are greatly appreciated!

 

PS. the ramps have no finish call out, will not be exposed to the end customer, and provide a pathway for air flow only. Our customer is more concerned with reduced cycle time and cost per part when it comes to these features.

Usually I use surface finish project , preferable with nci as the source.

there is a path called finish leftover hiding away.

u can use use comand finder on home strip to get it out.

Ask them for a bigger radius to reduce the run time. Trust me air don't care if that is a .187R over the .0625R. That alone would save them a lot of time if they aren't so picky and want cost reductions. Make in manufactureable if not shut up and be happy you got what you got.

 

Blend with the 2 outside edges to drive the toolpath. That will create a nice flow path for the air and they will like the cosmetics of that toolpath in that shape. I have pointed arrows to the one edge we can see have to assume a mirror of this edge on the other side.

I was able to find it by right-clicking. Thank you very much, sir. I have never even seen or heard of that toolpath but it worked perfectly for what I am wanting to do. Thanks again for learnin' me sumthin' new:)

Misunderstood I was thinking you wanted to machine the whole shape with the 1/8 ball endmill. Yes Steve pointed you in a good direction to remove the left over stock.

We have worked with this customer on changing/tweaking features before... last time I did that I had about a 1.5 week delay while they updated the solid on their end and created a new rev so there were no issues at incoming inspection. Machine sat too long waiting on customer approval/updates, jobs behind that had to get pushed back, etc.  I am taking this opportunity to avoid the delays on their end with a new rev and trying to gain some programming experience at the same time:) Thank you for taking the time to reply, all feedback is greatly appreciated on these forums.
