Torch Table Prototype II Design

Torch Table Prototype I

Overview

The CNC Torch Table is a table capable of cutting 2D shapes out of steel. It is a valuable tool for replication because of this capability. Many parts that make up the 50 GVCS Tools can be cut on the CNC Torch Table.

The CNC Torch Table provides a quicker solution for cutting sheet metal, especially into intricate patterns that are difficult to cut by hand.

The 2nd prototype is currently being designed and prototyping will take place in June 2012.Chris DeAngelis 03:41, 8 June 2012 (CEST)

Status

Prototype I Currently being used in experimental production runs. Tighter integration of Digital Fabrication is being researched as is the software toolchain (which is a current bottleneck).

Prototype II In progress.

Plan of Action

• Perfect mechanical design for replicability to 1/32" over 4x8' area
• Find open source controller, end stops, and z height automation/detection.
• Design ergonomic frame and motracks and gantry on it
• Possibly use full gas flow control - this may be beyond the scope of the present program - as it would require expensive parts until we can manufacture them ourselves.
• Open source stepper motors would be a good addition - if we could find somebody to design/fab them - that would be great.
• Computer vision for fully automated cutting would be the last step.
• Next steps: stiffening frame design to accommodate router heads
• Interview with owner of Ben's excellent DIY table setup in Smithville, TX:
