Ramping into a pocket

Post by Wdp67 »

Hey all!! Thanks for helping me on my earlier post about Mach3. Finally making some real parts, and trying to use the ramping feature in a pocket. I can't seem to get it to work, can someone walk me thru it? Basically what I am trying to do is face of my workpiece, but I need the tool to not plunge straight down into my material. I got it to work once by accident, but can't for the life of me remember how I did it.

Thanks!!

Walt

After selecting Pocket tool path, check the box that says you would like to consider advanced options. I believe it is in the upper most box.

About two thirds of the way down the menu there should be a box that allows you to ramp plunge moves. It can be selected, and will ask you the distance over which you would like to plunge.

I think that is what you are looking for.

Yes that's it but when I do it, it doesn't ramp, it still just plunges strait down into the material.

Did you Recalculate Toolpaths and then save the new toolpath?

Yes sir, I tried it several times, looked at the code and there was no ramping. Late last night I shut my computer down and restarted. When I tried it again it worked. I'm not sure what was going on, but I did get it to work.

Thanks for your help!

Can you post a couple of screenshots of how you have it set up as that will help the board experts doesn the wireframe toolpath view not show the ramp ??

It was working yesterday just fine and I changed my material size from 4x8 to 5x5 once I recalculated and saved the toolpath and ran the part, no ramp.

Now I changed the bit to a 1/2" and the ramp shows up which is really the bit I should be using I know but anyway I changed back to the 1/4" bit and changed the step-over to 80% and that did it! Hopefully all this is helpful to someone down the line.
