Surface Rough Pocket

[PrototypeFred]

Hi : I have a part that has a large pocket. I ran a

Surface rough Pocket on to remove most of the material and I left .100 of stock.

Now I just want to go back and remove the remaining stock (.100 ) and achieve a good finish.

Does anybody have a good suggestion as to what kind of tool path I should use for this ?

I am willing to email this file to anyone to better help me out.

I really don't know what I am doing wrong and I would need some guidance with this. All help would greatly be appreciated.

Thanks

Hi Fred, have you tried a "surface finish contour" toolpath? This would finish the walls but you'd have to make a pocket program for the floof. If the walls are vertical you could also use a 2d contour toolpath and set your cotour type to "ramp". Or you could use surface rough restmill but this may cause extra rapid moves when it gets to the floor.

Send it over Fred.

I have used surface rough pocket as a semi finishing toolpath. I just uncheck the roughing to get it close. As far as finishing I would need to see the file before I could give you an idea on that.

After several issues I have had to upload it on the FTP site (Thanks to Jay K. for putting this website up !!! ) .

The file name is: STROBE YOKE CVR REV 1

Thanks to all !!!

Just so you know Fred, a 37MB file is a bit big. Anything over a couple MB should be zipped. It just makes it a little easier on people trying to help you.

Thad :

Hardmill told me the same. But next time I will try these suggestion.

Thanks for the advice.

After looking at your part...

 

 

I would have roughed closer, say .015 to .03 away from finish size.

 

A waterline and scallop tool path using a 1/4" ballnose with a .005" or less stepdown/ stepover should yield nice results. Follow up with a pencil toolpath and a ballnose equal to or smaller than your smallest fillet radius to finish.

It depends on the geometry/material alot for me but generally I'll do a Surface Rough Pocket to within .04, Surface Finish Parallel to .01 with a .05 stepover to semi-finish and then go from there with either Surface Finish Contour or Parallel or whatever else it takes. The reaso I run the semi finish is alot of times I'm using smaller endmills to finish (darn engineers and their .02 radii)so I try to get out as much as I can first. hth.
