CNC Torch Table

CNC Torch Table Prototype I, used in 2011 Production Run

Torch Table Prototype II Design.

Summary

The CNC Torch Table (aka RepTab) is an enabling machine for any workshop. This machine enables creation of custom parts for fabrication or replacement of broken components.

The CNC Torch Table allows workshops to create replacement parts on the fly for many of the components used in the GVCS. Additionally, the Torch Table gives workshops the ability to create many of the custom components used in the GVCS Machines. Many parts that make up the 50 GVCS Tools can be cut on the CNC Torch Table, making this machine valuable for replication.

Status

The 2nd prototype is in progress, more information about the control system and research and development can be found in the Research & Development section.

The mechanical structure is already built. Prototype 2 build integration is scheduled for June, 2013, as an enabling tool for digital fabrication of the mechanical GVCS tools such as tractors and bulldozers. Steps needed include Steppernug open source stepper motor driver, Arduino stepper controller, z-height control, trigger, endstops, and CNC toolpath toolchain. Further development involves test-driven design with Cool DRV, RAMPS, DRV-based Pololu. Building towards universally scalable stepper controller as we begin Power Electronics Construction Set.

Additional Notes

• As a large x-y-z coordinate table, the Torch Table has potential applications with other tooling besides a cutting torch. One limitation is that the drive system is not powerful enough or stiff enough to support heavy cutting-tool forces.
• A modular tool mounting (possibly dual mounting, so two tools could be available simultanously) would facilitate tool changeover.
