Re: [CAD_CAM_EDM_DRO] Re: oscillating z....

Just out of curiosity, is this for making some special finish on something, or
taking miniscule bites out of something super hard? This thread reminds me of
an old welder I knew years ago, who could take a cutting torch and make a
perfectly straight, glass smooth cut, just where it was wanted, but the entire
time he'd be shaking like a whore in church due to alcaholism.....
