cutting corrugated steel

Will THC track properly over corrugated steel @ 250 ipm ?

This one says 180ipm.

Thanks..I don't see why it wouldn't track correctly at higher speeds.

If the corrugations are at a 45 degree angle then the thc needs to be able to move the z as fast as your x & y are traveling. If they are steeper then it needs to move faster.

This may depend on your particular plasma table and your thc. Are you using Plasmacam with Advanced Height Control, or another brand?

You will have to have advanced height control and adjust your Z axis speeds, height tolerance, and climb/dive zones. It's tricky but it can be done with a good understanding of height control. As dj said, pretending that the corrugations are 45degrees you'd have to have a cut speed equal to or less than your maximum Z speed. The Plasmacam Z motor is capable of up to 104.5 inches per minute.

Thanks for that information Robert! I do have advanced height control, but have not yet attempted to cut corrugated material.
