OPTIMIZATION OF TECHNOLOGICAL PARAMETERS IN THE DRILLING PROCESS OF A6061 ALUMINUM USING THE FINITE ELEMENT METHOD

Abstract

Drilling A6061 aluminum alloy is a common operation in mechanical manufacturing but often encounters problems such as large heat generation, chip adhesion, dimensional deviation and rapid tool wear when selecting inappropriate technological parameters. This study uses the finite element method (FEM) to simulate the A6061 drilling process using Abaqus software. The workpiece material model is built according to Johnson-Cook standards, 3D drilling tools are set up with variable boundary conditions and technological parameters including cutting speed, feed rate and drilling depth. Simulation results allow analysis of chip formation, stress-strain distribution, and at the same time determine the relationship between technological parameters and cutting force and quality of drilled holes. On that basis, the study proposes an optimal set of drilling parameters to reduce cutting force, limit tool wear and improve machining accuracy, contributing to increased productivity and quality in mechanical manufacturing
