2 x 1 (1x1,2x2) Tubing (CAM)

In order to machine Aluminum 1x1s, 2x1s, and 2x2s, a CAM profile must be made first. The idea is the same, but for Aluminum Tubing we use a custom-made jig that speeds up the machining process. The following text outlines the procedure on creating a CAM for Aluminum tubes.

Create a new setup for any new orientation (vertical, horizontal, different horizontal from previous)

1. Remove additional stock

2. Set origin and axes according to 2x1 jig

3. Z-axis: vertical and positive is up

4. Y-axis: horizontal and along the jig (same as aluminum plate/polycarb)

5. X-axis: horizontal and perpendicular to the jig (same as aluminum/polycarb)

6. The origin for the 2x1 jig is on the left side (from Mr.Shinta’s desk view) so in CAM the X-axis should be perpendicular to the 2x1 and facing away from it

Add Operations

1. Use MVRT template for 2x1 and select correct operation

Drill: select one of the holes and it should automatically select all the holes along the 2x1

Contour: select for bearing holes/ any other geometry, select the appropriate geometry

Parting: use this for cutting the 2x1 to length, press ALT key and select one edge of the 2x1

Symmetrical 2x1s allow one CAM profile to be used for both sides; be careful and make sure that the 2x1 geometry is symmetrical and if not, duplicate the previous setup, and edit the operation that needs to be changed
