Fusion 360 CAM AI Assistant

An AI-powered CAM workflow assistant for Autodesk Fusion 360. Analyzes geometry, suggests stock setup, toolpath strategies, and learns from your preferences.

Built as an extension to Fusion-360-MCP-Server by @AuraFriday.

What It Does

• Analyze Geometry — Extracts CAM-relevant features (pockets, holes, contours), calculates bounding boxes, identifies minimum tool radii
• Suggest Stock Setup — Recommends stock dimensions and orientation based on part geometry and your preferences
• Recommend Toolpath Strategy — Suggests roughing/finishing approaches, tool selection, feeds and speeds
• Learn from Choices — Stores your preferences and improves suggestions over time

Installation

Prerequisites

1. Autodesk Fusion 360 installed
2. MCP-Link Server from AuraFriday's releases

Install the Add-in

1. Clone this repository:

   git clone https://github.com/YOUR_USERNAME/fusion360-cam-assistant.git
   

2. In Fusion 360, press Shift+S to open Scripts and Add-Ins

3. Click the green + next to "My Add-Ins"

4. Navigate to the Fusion-360-MCP-Server folder in this repo

5. Click "Run" to start the add-in

6. Check the TEXT COMMANDS window (View → Show Panel → Text Commands) for connection status

CAM Operations

get_cam_state

Query current CAM workspace state.

{
  "operation": "get_cam_state"
}

Returns: setups, operations, stock configuration, post-processor info.

get_tool_library

Query available cutting tools.

{
  "operation": "get_tool_library",
  "filter": {
    "type": ["endmill", "drill"],
    "diameter_range": [3.0, 20.0]
  },
  "limit": 50
}

Returns: tools with diameter, flutes, lengths, vendor info.

analyze_geometry_for_cam

Analyze part geometry for manufacturability.

{
  "operation": "analyze_geometry_for_cam",
  "body_names": ["Part1"],
  "analysis_type": "full"
}

Returns:

• Bounding box with dimensions
• Volume and surface area
• Detected features (cylindrical, planar, conical)
• Minimum internal radius (for tool selection)
• Orientation suggestions with scores

suggest_stock_setup (coming soon)

Recommend stock dimensions and orientation.

suggest_toolpath_strategy (coming soon)

Recommend machining strategies, tools, and parameters.

record_user_choice (coming soon)

Store feedback for preference learning.
