Method for determining a minimum width and an attachment position of a microjoint and method for machining a workpiece

A method for determining a minimum width of a microjoint by which, when machining a workpiece, a workpiece part remains connected to a remaining workpiece of the workpiece, which comprises:

• determining the minimum width of the microjoint in dependence on at least one machining parameter which influences a relative position of the workpiece part in relation to the remaining workpiece during the machining of the workpiece, wherein the machining of the workpiece includes thermal cutting of the workpiece with a machining beam;
• wherein the minimum width of the microjoint is determined in dependence on the at least one machining parameter in a form of a gas pressure of a cutting gas leaving a machining nozzle that acts on the workpiece part during a cutting free of the workpiece part from the remaining workpiece.
