Surface Rough Pocket

[Guest]

When using a surface rough pocket operation is there a way to limit the depth where you want the tool path to stop or must you use absolute depths to control the depth of the routine?

[Cuda84]

I alwats use absolute depths. As far as I know that is the only to get them to start where you want them too also.

Or create a floor surface.

Thad,

 

Create a floor surface and set it up as a check surface?

 

Is that how you do it?

[smokey_44]

Just use a flat surface where you want the tool to stop

Or depth limits

Absolute depth limits

[Müřlıń®]

If you want the pocket to skip certain areas of your part, then close off surfs must be constructed because of the no nesting chain rule.

Same for Surface/finish/contour.

 

Otherwise, absolute depth is the ticket...

I use absolute or create a flat surface.

 

It would be nice if you could have nested chains like 2d pocket!

Ive always acheived better results from abs depths.

John,

 

I make the floor drive, but if it's a BS surface that really doesn't mean anything, you could make it check.

 

My guess is that you have a situation where absolute depth limits will work in one area, but then not get to full depth in other areas. Or vice versa. If so, you could always create different boundaries with different depth limits and then post the multiple ops together. Even this won't work 100% of the time though.

It's my first op 99% of the time. Absolute Depths is the way to go. I use a slab surface at maximum depth if I need the tool to go outside of my true cutting area to get into a nook or cranny where helix or ramp can't be accomplished.

 

I know there is the option to plunge outside of tool boundary which would eliminate the need for teh slab, but I am not all that comfortable with IT.

Thanks for all the advice guys

You're correct Thad, I had an area where I did not want to get to the full depth.

 

I did get it to do what I needed.

I agree with Thad use multiple boundaries with seperate absolute depth limits for each one and seperate programs save yourself a lot of headaches
