1 Operators know the scene: chips pack a 50 mm-deep pocket, the re-cut chips weld, the tool snaps, the spindle alarms. Aluminum’s low density and high thermal conductivity make chips sticky; tight corners and long stick-outs trap them. Existing rules of thumb—open flutes, flood coolant—fail when pockets exceed 3×tool diameter. This study quantifies the combined effect of tool geometry, coolant pressure and tool-path kinematics on chip evacuation in 2025 production conditions. 2 Research Methods 2.1 Design of Experiments Full 2³ factorial with center points (n = 11). Factors: • A: Helix angle—38° (low), 45° (high). • B: Coolant pressure—40 bar (low), 80 bar (high). • C: Path strategy—adaptive trochoid vs conventional raster. 2.2 Workpiece & Machine 7075-T6 blocks, 120 × 80 × 60 mm, pockets 10 mm wide × 50 mm deep.
