The core algorithm of CNC machining is interpolation-the process of generating intermediate toolpaths based on known points. Common interpolation methods include:
Linear Interpolation: Suitable for planar machining operations, such as milling rectangular slots.
Circular Interpolation: Used for machining circular or arc-shaped features, such as for hole positioning.
Helical Interpolation: Combines axial feed with rotational motion to facilitate the machining of threads or complex curved surfaces.
Application Scenarios: From Single-Piece Customization to Mass Production
The inherent flexibility of CNC machining has led to its widespread adoption across numerous fields:
Aerospace: Machining high-precision, lightweight structural components-such as aircraft wing spars and engine blades-typically utilizing materials like titanium alloys and superalloys.
Automotive Manufacturing: Mass production of components such as engine blocks and transmission gears, enabling efficient changeovers between different parts through the use of specialized fixtures and programming.
Mold Manufacturing: Machining the cavities and cores of plastic injection molds, achieving surface finishes of Ra 0.8 μm or finer to meet the rigorous demands of injection molding processes.
Medical Devices: Manufacturing personalized components-such as artificial joints and dental implants-which requires the integration of multi-axis machining techniques with precision inspection processes.
