3. Manufacturing Process of CNC Ducati Parts
Design and Programming
Engineers start by using CAD (Computer – Aided Design) software like SolidWorks or Fusion 360 to create detailed 3D models of the parts. They take into account the specific requirements of the Ducati motorcycle, such as the engine’s performance needs, the bike’s handling characteristics, and the aesthetic design. Once the design is complete, CAM (Computer – Aided Manufacturing) software is used to convert the CAD model into toolpaths. The CAM software optimizes the feeds and speeds based on the material being used. For example, when machining aluminum parts, the spindle speed may be set between 10,000 – 20,000 RPM, and the feed rate could range from 500 – 2000 mm/min.
Material Preparation
The raw materials, whether it’s an aluminum billet, a steel bar, or a carbon fiber pre – form, are prepared before machining. They are cut to near – net shape to minimize the amount of material that needs to be removed during CNC machining, which saves time and reduces waste. For high – strength materials like some steels and titanium alloys, pre – heat treatment such as annealing may be carried out to soften the material, making it easier to machine.
CNC Machining
- Roughing: In the roughing stage, large end mills are used to remove the bulk of the material quickly. This stage prioritizes speed to reduce the overall machining cycle time. For example, a 10 – 20 mm end mill may be used to rapidly remove material from an aluminum billet when manufacturing a Ducati engine block.
- Finishing: After roughing, smaller tools, typically 3 – 6 mm carbide end mills, are used for the finishing operations. This is where the tight tolerances and smooth surface finishes are achieved. For parts like cylinder heads, the finishing process ensures that the surface finish is within the range of Ra < 1.6μm, which is crucial for proper sealing and engine performance.
- Multi – Axis Machining: Many Ducati parts, especially those with complex geometries such as suspension link arms or some engine components, require multi – axis machining. 4 – axis or 5 – axis CNC machines are used to create these complex 3D shapes in a single setup. This reduces errors that could occur from multiple operations and ensures a more precise final product.
Post – Processing
- Heat Treatment: Parts made from materials like steel, such as sprockets or some engine components, may undergo heat treatment processes such as quenching and tempering. This hardens the surface of the part, increasing its wear resistance. The hardness of the part can be adjusted to a specific Rockwell hardness scale (e.g., 50 – 60 HRC) depending on its application.
- Surface Finishing: Anodizing is a common surface – finishing process for aluminum parts. It not only adds corrosion resistance but also provides a decorative finish in various colors. Powder coating is used for steel parts to enhance their durability and appearance. Polishing is often carried out on parts where a smooth surface is required to reduce friction, such as in some moving engine components.
Inspection
CNC – machined Ducati parts undergo strict inspection procedures. Coordinate Measuring Machines (CMMs) are used to verify the dimensions of the parts, ensuring they meet the tight tolerances specified in the design. Optical comparators are used to check the surface finish. For critical parts like engine valves or transmission gears, non – destructive testing methods such as X – ray or ultrasonic testing may be employed to detect any internal defects that could affect the performance and safety of the motorcycle.
