By means of the jump-in control working units can be delivered to an exactly defined date. As well as additional devices like blow nozzles, spraying device and like can be switched on and off workpiece-independently.

The following three deployment parameters play an important roll in jump-in controls:

• deployment duration: position and length of the processed workpiece side
• deployment intensity: low deployment intensity creates soft/round shapes; high deployment intensity creates sharp-edged/ edged shapes
• deployment depth: measurement of the chip removal, width and thickness respectively of the remaining workpiece.

Fundamentally there are two kinds of deployment control:

• insertion and stopping/ pulse duration
• workpiece-controlled: An on-switch and a contactless sensor triggers the unit whilst passing the workpiece
• time control: the unit will be delivered to the workpiece after a set deadline. After an adjustable deadline the unit will be retrieved from the workpiece. The deadline starts passing a finishing-switch or contactless sensor.
• CNC-controlled: A computer control makes the unit deploy or stop corresponding to the preprogrammed parameter duration, process of the intensity and process of the deployment depth. This is described as a continuous path control. With this kind of jump-in control the workpiece can be given a new shape. In earlier times, the design have been realized with templates.
