1.1 Definition of Dynamic Milling Cutters
Dynamic milling cutters are rotary cutting tools designed for dynamic milling processes, optimized for large cutting depth, small cutting width, and high feed rates. They minimize cutting vibration and heat accumulation through continuous, smooth toolpaths, enhancing machining efficiency and tool lifespan.
Key Characteristics of Dynamic Milling:
Constant Tool Engagement Angle: Ensures uniform, low cutting forces for complex contours and hard-to-machine materials.
Tool Adaptability: Requires high toughness, wear resistance, and geometric optimization to support high-speed cutting and frequent path adjustments.
1.2 Key Features of Dynamic Milling Cutters
(1) Geometric Design
Flute Length & Rigidity: Combines extended flute length with high rigidity to balance cutting depth and bending strength, preventing vibration or breakage.
Flute Count & Chip Evacuation: Multi-flute design (e.g., 4 flutes) boosts efficiency, while wide chip flutes ensure smooth chip removal under small cutting widths.
(2) Material & Coating
Core Material: Jinlu tungsten carbide (WC) for superior hardness and impact resistance, ideal for steel, stainless steel, and titanium alloys.
Coating Technology: Advanced coatings like TiAlN and Blue Nano enhance heat resistance and durability.
(3) Cutting Parameter Compatibility
High Speed & Feed: Supports 5000+ RPM (for aluminum) and precise feed per tooth (FPT) of 0.03–0.08mm/z for optimal surface finish.
Path Optimization: Compatible with complex toolpaths (e.g., trochoidal or helical milling) to reduce abrupt load changes.
1.3 Applications of Dynamic Milling Cutters
High-Efficiency Roughing/Finishing: Reduces tool changes for mold steels (e.g., SKD11) and hardened steels (HRC45+).
Complex Contour Machining: Achieves aerospace and automotive part precision via CAM-generated toolpaths (e.g., UG NX).
Hard-to-Machine Materials: Titanium alloys and high-temperature alloys (e.g., Inconel) require coolant or oil-mist cooling.
