My company is being asked by a customer to make some tiny titanium washers.
4.5mm x .61mm and they have a very tight flatness and parallel tolerance range, .005mm.
On our Sodick AG600L, as far as I know a general purpose machine, we are running into a tiny amount of curve while cutting.
The wire enters at one side of the blank, and as it cuts to the center of the cylinder the kerf is shrinking on the order of .002mm.
This of course is making it tougher, not impossible, to hit the flatness and parallelism tolerance.
Any tips on reducing that curve that results from the change in thickness of the part while cutting?
I am already running the current and voltage down as low as I can and still cut for a decent single pass surface roughness of the part.
And the tension is already near the maximum the machine can tolerate with .010 brass wire.
