Motion between Entry Motion and Dynamic Mill

[Metals and materials]

SO.... I am using 2D Dynamic mill to remove material from below surface.  I am keeping Entry motion as Helix only. When backplotting the toolpath, once helix entry is done, the tool goes back to original position, and then starts with the cutting toolpath. I want to remove that motion.

Please point me where am I doing something wrong. Attaching screenshots below. THank you in advance,

That tool path believes that you are using that helix as an entry point....it helixs to create room for the tool to plunge and start cutting....it is how it's supposed to function.

I suppose you "could" try the "Toolpath Editor" but that can create its own headaches..

Right click on the toolpath, scroll to the bottom of that menu, you should see toolpath editor.

 

Myself, I would look to another tool path. That possibly looks like a good option for Contour Ramp

I'm not sure that is right. To me it looks like it is doing a profile ramp since his cutter plus his helix radius is probably too large to run that helix in between his chains.  The other thing could be since he has helix Center on Point and he might not have a point selected.

Yeah, too large of an entry helix creates some very janky stuff at the transition between entry motion and cut motion.

From what I have seen is because it sees material on both sides of the tool, and conventional mills in the helix, and then has to reposition itself to climb mill in the actual cut motion.

Reducing the helix radius always made this go away.

Sorry to bump an old thread..... But I encountered issues today with programming a helix entry for dynamic mill.  Using a .750 endmill and helixing into a .500 wide slot. I chose a helix radius of .475 (to remove more material as it was ramping down) and it was trying to conventional mill in the helix and switch to climb for roughing. For some reason, anything over 50% of the tool diameter for helix radius changes the helix from climb to conventional. I am curious why MC would do this??

I think it "sees" material on the other side of the tool.

I think I am more curious as to how you're using a .750" endmill to helix into a .500" slot.

I always use profile it runs faster.

 

For that use contour ramp. It's going to take forever to dynamic that

that's a whole lotta positive cutter comp right there
