Abstract
The paper presents the results of 3D modeling the process of abrasive waterjet cutting of structural carbon and stainless steel workpiece. The Johnson-Cook model is selected as a material model. Distributions of stress fields in the cutting zone are obtained, as well as the dependences of depth of cut on jet traverse rate at jet velocities of 400 ... 700 m / s and dependences of cutting force on jet velocity at jet traverse rates of 100 ... 400 mm / min.
Highlights
Debugging of technological parameters of abrasive waterjet machining of various materials during experimental studies is in many cases a difficult task; the use of numerical modeling of the process of abrasive waterjet cutting in order to establish rational operating parameters is relevant [1,2,3,4]
The jet velocity varies from 400 m / s to 700 m / s, and the traverserate - from 100 mm / min to 400 mm / min
One of the main steps is the selection of a suitable material model
Summary
Debugging of technological parameters of abrasive waterjet machining of various materials during experimental studies is in many cases a difficult task; the use of numerical modeling of the process of abrasive waterjet cutting in order to establish rational operating parameters is relevant [1,2,3,4]. The problem of modeling of abrasive waterjet cutting of structural carbon (AISI 1010) and stainless (AISI 321) steels was considered. A liquid jet with a diameter of 1 mm containing abrasive particles is modeled by the SPH method [5].
