Introduction

Frames can be manufactured by hand, with careful measurement and drilling. While meditative, this work is repetitive and laborious. Time studies of the hand production process using a drill press reveal that positioning the undrilled frame stock for precise drilling consumes the majority of effort. Automating the process in an affordable manner will reduce cost, increase availability, and free time for creative effort.

Challenges

Reducing cost and improving availability of frames requires decentralized manufacturing.

Approaches

A frame drill built from standardized and widely available industrial automation components allows anyone to source the parts they need anywhere to build more frame drills.

Dual gripper drill

This frame drill design makes use of two independently controlled and actuated industrial grippers to move and hold square stock for drilling on all four sides by independently actuated high speed spindles.

Villagekit Grid-bot

https://github.com/villagekit/grid-bot

A multi-spindle single-axis CNC.

For the framing, we'll use 8040 aluminium extrusion since it's fit for purpose and readily available here in New Zealand.

Where possible, we'll try to use motion control components found in “pro” consumer CNC machines (AvidCNC, RoverCNC, QueenBee, etc), e.g. stepper motors, lead screws, linear rails, etc.
