Vertical Edge Detection and Compensation?

Post by CCWashout »

Hi all,
.
I have just partially run a 3D finishing tool path on a job in aluminium and due to some oddities have stopped it in case I am 0.2mm from catastrophe ;-)
.
I have roughed out the shape fine using a 6mm end mill (single flute carbide) and left 0.2mm allowance for finishing.
.
The toolpath I am half way through is a finishing pass in the X followed by a finishing path in the Y. I'm using a 4mm carbide ballnose (24000RPM and about 800mm/min - probably should be faster but I went for the least aggressive setting in GWizard).
.
The reason I have stopped the job is at some points during the cut the toolpath essentially plunges into the material where there is a vertical surface aligned to the major direction of travel i.e. aligned to X and then tries to "profile" along that edge with much shrieking involved. So far the verticals have been fairly shallow e.g. 2mm or so, but I'm approaching a full depth edge which is at 16mm deep and I have a concern that unless Cut3D has vertical detection and some kind of compensation its going to "fall over that cliff" and try and profile 16mm deep and 0.2mm wide. This would obviously be bad, as for a start the flutes on the cutter are not that long and I doubt the tool could handle the forces.
.
So the question is does Cut3D have vertical edge detect and compensation i.e. run into that area at whatever the tool depth setting is and use multiple passes rather than trying to take it all at once?
.
Thanks in advance
.
PS. I'm going to try profiling the shape using a cut out path to take the material off of that area for safety, but asked in case I am worrying unnecessarily.

The answer is no. Cut 3D will go to the max depth on the finishing pass. It assumes you have already run the roughing pass with just a small amount left to finish with the finishing pass.
