Student CNC bracket run

Low-volume aluminum brackets fabricated under supervision for a local irrigation startup.

Tools

  • 3-axis CNC mill
  • Digital calipers
  • Deburring fixture

Materials

  • 6061 aluminum
  • Threaded inserts

Outcomes

  • 30 parts delivered
  • Two students earned CNC badges

A local irrigation startup needed 30 brackets for a pilot deployment. The job allowed students to practice workholding and inspection while keeping the volume manageable.

Setup strategy

Students used a modular vice plate to reduce setup time and documented every clamp position for repeatability.

Inspection process

We measured three dimensions on every part and logged them in a shared sheet. Two parts required rework due to a tool offset error.

What we learned

Having a documented setup sheet allowed the evening crew to pick up the job without needing the supervisor on-site.
