Programming efficiency starts in the CAD stage.
A clean model equals clean toolpaths — and fewer errors downstream.
Model Preparation
Before entering CAM, ensure your model:
-
Has no gaps or duplicates.
-
Uses real-world units and orientation (Z = up).
-
Includes stock boundaries or fixture geometry for visualization.
Setting Up in Fusion 360
Create a Manufacturing Model separate from your design model.
This allows you to hide hardware, add stock, and manage setups independently.
Fixture Planning
Import vises, clamps, or vacuum pods as components.
Align your WCS origin to a consistent point (usually top of stock, front-left corner).
Simulate to verify tool clearance.
Post-Processing Consistency
Use one verified post processor per machine.
Rename files systematically:Company_WO12345.nc
Include header info: part name, material, tool list, and revision date.
Iterative Design Feedback
CNC machining isn’t linear — it’s a loop.
When you see chatter, adjust model geometry or tool reach.
When you see excessive cycle time, modify toolpath strategy.
Lesson
A disciplined CAD-to-CAM workflow eliminates guessing.
Your goal is to make every job “push-button repeatable” — same setup, same code, same result.
