Overview

A learning project: I'm just starting to learn Fusion 360's CAM workspace, and I'm using a coaster to practice programming and simulating a toolpath.

The complete CAM simulation, from the spindle's first approach to the finished spiral pocket.

Engineering challenge

I'm just starting to learn Fusion 360's CAM workspace, so I picked a coaster as a first part to get hands-on with programming and simulating a toolpath before ever cutting material.

Design process

I set up the coaster blank and fixturing in Fusion 360, then used the CAM workspace to program the spiral pocket toolpath shown in the video.

Before cutting anything, I ran Fusion's full toolpath simulation to check the spindle's motion and the resulting pocket geometry.

Testing & results

The CAM simulation runs cleanly end to end (video above), and the finished coaster is in the gallery below. Next I want to try programming a toolpath for a design of my own.
