Vectric carve on CNC
Now it’s time to use the 1/16-inch diameter, bullnose and mill for the finishing pass on this bar carving. There isn’t much material to take off in the finishing pass since the roughing pass takes most of it off. I was able to run this finishing pass at 150 in./min., but think I could’ve gone up to 200 without an issue.
I did use Vectric CNC software to create my tool paths.
Using a 1/16-inch diameter bullnose mill for the finishing pass in CNC machining is a common choice for highly detailed work and smooth surface finishes. Since the roughing pass removes the bulk of the material, the finishing pass focuses on refining the surface without removing much stock, preventing tool overload and ensuring precision. Running the finishing pass at 150 inches per minute (IPM) is a balanced approach that maintains part integrity while optimizing machining time. Experienced CNC users often experiment with increasing the feed rate up to 200 IPM if their machine and setup allow it, improving efficiency without sacrificing quality. However, it’s essential to monitor the spindle load and part quality during higher feed rates to avoid chatter or surface damage. Vectric’s CNC software simplifies the creation of tool paths for complex carvings. It offers users the ability to customize settings such as step-over, ramping strategies, and feed/speed control, which are critical for achieving clean finishes. The software also supports simulation features that provide previews of the machining process, helping operators anticipate issues before actual cutting. Additionally, integrating a high-quality clamp system, like low-profile clamps, helps secure the workpiece effectively without obstructing tool paths, which is essential for uninterrupted carving operations. Proper machine setup, including spindle speed adjustments and tool calibration, also contributes significantly to the quality of the finishing pass.

Users working with Onefinity CNC or Redline CNC machines can benefit from shared experiences and tool recommendations related to finishing passes and the use of various bits. In summary, the finishing pass with a 1/16-inch bullnose mill powered by Vectric tool paths demands attention to feed rates and machine settings. Monitoring spindle speed and feed rate through Vectric's software, combined with effective clamping and machine calibration, ensures a smooth, high-quality finish on detailed carvings.
