CNC Torch Table

Overview

Torch Table

The CNC Torch Table is a table capable of cutting designs out of metal with a 2-axis torch controlled by computer.

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

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

• First step: perfection of mechanical design for replicability to 1/32" over 4x8' area
• Need open source controller, end stops, and z height automation/detection.
• We could use existing structure, with modifications. Right now we use gear rack. We can simplify the carriage structure.
• If we want to go all out - we could use full gas flow control - but that is probably 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:

• CandCNC setup used by Ben (dragon-cut 620 AIO); $1478
