This paper studies aluminum alloy heat sink machining with complex multi-sided features and thin-walled vulnerable areas. It optimizes process planning, designs a dedicated fixture, conducts milling force calculation, finite element analysis and VERICUT simulation to reduce thin-wall deformation and guarantee dimensional and positional accuracy.
This paper studies CNC machine tool machining error control. It analyzes multi-source errors including structural stiffness deformation, thermal drift and motion chain cumulative deviation, and verifies the synergistic error suppression method via vertical CNC machine tool comparison experiments to improve dimensional stability for high-end component machining.
This paper presents an intelligent online verification system for CNC machining developed by Shanghai Turbine Works for CNC tool compensation parameter verification. It adopts QR code automatic data entry, multi-dimensional parameter checking and tool reliability assessment to eliminate manual input errors, avoid tool collision, improve machining quality and cut manufacturing costs.
