Toolpaths and Machining: Custom Form Tool

Carveco Tutorial: Creating Custom Form Tools

In this tutorial, you'll learn how to define and use Custom Form Tools in Carveco Maker Plus. This feature is ideal when using specialty tooling that doesn't match standard end mill or V-bit profiles.

🔹 What is a Custom Form Tool?

• Custom tools have unique profiles (e.g., ogee, round-over, cove) that cannot be defined by standard parameters alone.
• Use an open vector representing half of the tool's profile to create the tool definition.

🔹 Drawing the Profile

• Use the vector drawing tools to sketch one side of your tool shape (Carveco will mirror it).
• Ensure the profile is open and ungrouped.
• Use precise dimensions or import from a DXF if provided by the tool manufacturer.

🔹 Creating the Tool

• Go to Create Custom Form Tool.
• Select your open vector when prompted.
• Review the mirrored preview and enter speeds, feeds, and a name.
• Important: Change units to inches per minute if necessary to avoid incorrect feedrates.

🔹 Simulating and Using the Tool

• Use the custom form tool in any toolpath that supports profiling or contouring.
• Simulate to verify the shape is applied correctly in 3D.
• If too deep, adjust the toolpath's cut depth or refer to the tool's radius for proper max depth.

🔹 Optional: Sharp vs. Rounded Corners

• When using a profile toolpath, check the Sharp Corners option to produce mitred, clean internal corners.
• This is useful for joinery or decorative edge work where rounded toolpaths aren't acceptable.
