flat endmill to mill a surface toolpath in copper electrode

[foolsh]

i just did a copper electrode with a sharp corner radius joined together in 3d contour.i tried a parallel surface toolpath but i couldn't apply a negative stock for spark gap.i wonder anybody tried other methods.i tried reducing cutter diameter to compensate for spark gap and lower z offsets to compensate for spark gaps but found mismatch with previously cut profile using ball nose cutter which couldn't cut a sharp 3d profile.i wonder could anybody help me out?thanks

Do a search on electrode cutting, this has been a well covered topic in the past be sure to read the whole threads.Good Luck, If you dont find what you need we,ll be here.

good day

if your form your cutting is a 3-d wireframe you could try to offset your geometry the proper amount and then use a 2-d or 3-d sweep to obtain what you are looking for . other than that if you absolutly need it sharp you may need to split it into two trodes. i personally stay away from lieing about cutter size for the exact reason you discovered. as corey stated do a search the topic has been covered quite a bit.
