Abstract
Method for producing a green body for a machining segment (51) from a powdered or granular first matrix material (56) and first hard material particles (57), the machining segment being connected by an underside (61) to a basic body of a machining tool. The machining segment (51) has a projection (Δ) of the first hard material particles (57) on an upper side (62) opposite from the underside (61).

1-10. (canceled)
A method for producing a green body for a machining segment from a powdered or granular first matrix material and first hard material particles arranged according to a defined first particle pattern, the machining segment being connected by an underside to a basic body of a machining tool, the method comprising a sequence of a first step and a second step carried out N times, N≥1, where:
- in the first step, applying a matrix layer having a first region and a second region, the first matrix material being applied in the first region and a powdered or granular supporting material different from the first matrix material being applied in the second region;
- and
- in the second step, arranging the first hard material particles in the matrix layer according to the defined first particle pattern, the first hard material particles being arranged in a transitional region between the first region and the second region.
The method as recited in claim 15 wherein the supporting material has a melting temperature higher than the sintering temperature of the first matrix material.
