Toolpaths and Machining: Using a Roundover Bit

Carveco Tutorial: Using a Roundover Tool

This tutorial demonstrates how to set up and use a Roundover Tool within Carveco Maker to create smooth, radiused edges on your parts. It includes how to configure your tool, build the toolpath, and resolve common machining issues.

🔹 Tool Setup

• Go to the Tool Database and add a new tool of type Roundover.
• Enter the Diameter (e.g. 28mm) and Arc Radius (e.g. 6.35mm or 1/4").
• Ensure the diameter is accurate, as this determines tool offset.
• Optional: Adjust step down, feed rates, and plunge rate.

🔹 Creating the Toolpath

• Use the Profile Toolpath with your roundover tool.
• Set the cut depth to match the arc radius (e.g. 6.35mm).
• Use Outside as the cut direction for outer edges.
• Enable Relative to Inner in tool settings to calculate proper offset.

🔹 Simulating & Troubleshooting

• Simulate both the roundover and cutout toolpaths to check alignment.
• If the roundover is removed by the cutout, it means the offset isn't set correctly.
• Adjust the tool’s diameter or offset values as needed.
• You can use positive or negative offset values to increase or reduce the visible roundover.

🔹 Real World Machining

• Use a roundover tool first, then cut out the part with a standard end mill.
• Ensure the roundover plunges outside the material to avoid tool damage.
• Use clamps and tabs to secure your material during machining.
• Test your setup to ensure the tool offset matches the real-world tool geometry.
