Week 9:

I began by going step-by-step through the guide provided. This ended up being quite a long process as the manufacture section of fusion 360 is new to me and it took a while to familiarise myself with the functions available.

I started by creating the mini tile:

 

At first I started drawing on the wrong plane. It was supposed to be the front one to make it easier when it came to the CNC simulation. I realised this when it came to creating the stock material as it looked completely off and not at all like what was in the guide. I re-created the part correctly  by looking at the cube at the corner of the screen which has each plane labelled so I could make sure the letter was on the front.

Dimensioning the stock material:

 

Setup includes:

-The tool (material, cutting diameter, corner radius)

-Operations (heights, passes, linking)

-Speeds

Tool:

With so much choice I wanted to learn more about what made certain materials appropriate for different types of cut needed or the materials you are milling.

Here are some useful websites explaining types of process and  drill

–https://toolholderexchange.com/cnc-cutting-tools-primer/ -good comparison of materials and examples of other types of CNC machining

–https://www.cnc.com/programming/-easy to understand explanation of programming and G-code.
