Integrated simulation system for 5-axis milling cycles

Popis výsledku v původním jazyce

Multi axis milling is a promising machining technology for manufacturing of complex geometries and surfaces designed in aerospace, automotive and die-mold industries. Thanks to the additional rotary axis, it provides flexibility to overcome the accessibility issues. However, as the cutting tool has additional degrees of freedom and ball nose end mills are used the process becomes even more complicated in terms of geometry, mechanics and dynamics with respect to the end milling operations. In this study, the dynamics and stability of 5-axis ball end milling operations is simulated throughout a given toolpath. The cutting tool-workpiece engagement boundaries are identified using distance field approach, where the in process workpiece is updated throughout the toolpath. The ethod using distance field features very low computational time demands, close to real-time simulation. Then, process stability is simulated in frequency domain in order to detect stable and unstable cutting regions along the toolpath. The cutting forces are simulated using orthogonal-to-oblique transformation. The simulations are verified through experimental results.
