Stream lag and taper are natural, but undesirable result of cutting with conventional waterjet. The faster parts are cut, the greater the stream lag. Stream lag causes part geometry errors. In addition, as cut speed is increased through a given material, the waterjet beam produces ever-increasing taper. Conventional waterjets must slow down in order to reduce or eliminate finished part tolerance errors caused by stream lag and taper.

 

With Active Tolerance Control, these limitation are overcome.
