Abstract
The method is used to drill at least one hole into a front wall section of a workpiece (12) by way of a machining jet formed from liquid, to which abrasive material is admixed as needed. As seen looking in the drilling direction, the front wall section is located in front of a rear wall section of the workpiece, which is disposed with an intermediate space at a distance from the front wall section. The hole is drilled at least partially by the machining jet impinging on the front wall section in a pulsed manner. This pulsed jet is generated by the recurrent interruption of the impingement of the liquid and/or of the abrasive material on the front wall section.

A method for drilling at least one hole into a front wall section of a workpiece by way of a machining jet formed from liquid, to which abrasive material is admixed as needed, the front wall section being located in front of a rear wall section of the workpiece, as seen looking in a drilling direction, the rear wall section being disposed with an intermediate space at a distance from the front wall section, wherein in the method
- the at least one hole is drilled at least partially by the machining jet impinging on the front wall section in a pulsed manner, the pulsed machining jet being generated by the recurrent interruption of the impingement of at least one of said liquid and said abrasive material on the front wall section.
A machining arrangement for drilling at least one hole into a front wall section of a workpiece by way of a machining jet, the front wall section being located in front of a rear wall section of the workpiece, as seen looking in a drilling direction, the rear wall section being disposed with an intermediate space at a distance from the front wall section, wherein the machining arrangement can be switched between a continuous mode, in which the machining jet formed from liquid and abrasive material continuously impinges on the workpiece, and a pulsed mode, in which the machining jet is pulsed, so that the impingement of at least on of said liquid and said abrasive material on the workpiece is recurrently interrupted, the machining arrangement comprising a controller which is programmed and configured so that said at least one hole is drilled at least partially in the pulsed mode.
