I'm new to Wire EDM and am having trouble with a roughing cut on this part. It is a lathe part that I am trying to cut a series of "U" shaped notches into a lathe turned part.
The cut is approaching perpendicularly to the axis of the part so engagement of the wire is very thin at the beginning of the cut, and gets thicker as it gets toward the middle of the part.
Under the current cut conditions, the wire broke almost immediately 3 times in a row.
This is on a Sodick ALN600G, .25mm brass wire
The material is Stavax with a diameter of 6.7mm
These are the conditions I was given by the controller:
(-----------ON--OFF---IP-HRP-MAO----SV---V---SF--C-PIK-CTRL--WK--WT--WS--WP---PC-----SK-----BSA);
C0001 = 0009 015 2215 000 271 +040.0 8.0 0037 0 000 0000 025 160 101 035 000000 000000 250099;
it seems like the varying thickness of the cut is what is causing the problem. I have a whole family of parts like this. Any recommendations?
