CNC Torch Table

Overview

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.

Product Ecology

The CNC Torch Table is important to the [GVCS]. Parts of the LifeTrac (arm mounting plates) require a level of precision that is difficult to replicate by hand. CNC ensures precisely measured torches.

Status

Currently on Prototype I, working with incorporating features into in OSE production runs.

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
