1. A method for cutting a workpiece with a cutting beam and a cutting fluid, which comprises the steps of:
successively cutting a waste workpiece part into at least two smaller waste part portions which directly border each other, the at least two smaller waste part portions separate from a surrounding remaining workpiece after the at least two smaller waste part portions have each been cut away, wherein a division into the at least two smaller waste part portions and an execution of a cut for separating a first part portion of the at least two smaller waste part portions takes place such that a cutaway point of the first part portion, the cutaway point which is cut first, lies inside an outer contour of the waste workpiece part to be cut away, wherein the division into the at least two smaller waste part portions and the execution of the cut for separating the first part portion take place such that the cutaway point of the first part portion lies in a radius about a center of gravity of the first part portion, wherein a circle area delimited by the radius takes up less than ⅓ of a total area of the first part portion.
