Week 11: 3D Parts on the 4 Axis

Overview

We will go over some best practices for the 4 Axis CNC.  Discuss our 4 Axis Assignments.  And a quick CAD demo of sweeping a line to make a shape.

 

Tabs

Tabs are a necessary evil with the 4 axis.  Take into consideration the best size and location for them.  If at all possible, incorporate them into your design.

Tabs can be resized and moved.

 

Saving Time

As you probably already know, the 4 axis is very exact, but takes a very long time to complete a job.

Always prepare your stock material as close to the ideal dimensions SRP Player gives you.  A few minutes on the lathe or the miter saw can save you many minutes (possibly hours) on the 4 axis.

The ideal dimensions are on the right in parentheses.

Thick Tabs

If your design can allow it, the thicker your tabs are, the shorter the time to mill them.

Oculus Medium CAD

  • Create your object in Medium and export
  • Convert your obj to an stl using makexyz
  • Mill your object on the 4 axis

 

For Next Week

Assignment

You will create an original 3D CAD model and cut it out on the 4 axis mill.

 

Final Project

Finals are right around the corner.  Start thinking about what you would like to do, what it will be made out of, and most importantly what machine(s) you’d like to use.
