The Open Source CNC Torch Table has achieved first fire and is now cutting parts for the open source tractor:
This is a sample cut through 1/2″ steel. It’s remarkably smooth, prior to cleaning the slag off the edges:
What is the news here?
- The price list for a 4’x8′ is about $800. The goal is performance equivalent to $10k and up price range commercial equivalents. Prtotype II aimed to be released by October 1.
- Open source controller will be milled with the open source CNC Circuit Maker for about $30 for 4 channels – aiming to complete this by October 1.
- Open Source Stepper motors to be produced via CNC laser cutter and CNC Lathe, also aiming for October 1. Contact me on this if you are a subject matter expert on the topic.
- Same structure may be strengthened by the use of thicker structural members for the carriage/gantry – allong for higher-torque functions such as CNC routing.
- The torch table is designed for retrofit with different working heads, including robotic arms for unrestrained degrees-of-freedom.
The development needs are for Full Product Release of the CNC Torch Table include:
- Shakedown of torch height requirements as a function of flame power for optimizing cut cleanness
- Addition of Z axis for height adjustment after piercing operations.
- Addition of height sensor.
- Open Source stepper motors and stepper motors controllers.
- Development of an oxy-hydrogen generator, for a cleaner burn, which would allow us to substitute imported acetylene (which is currently in short supply and more expensive due to an explosion at an acetylene plant) with electrolyzed water as the cutting fuel.
Other worthwhile goals, perhaps during the evolution phase after Full Product Release – would be the addition of computer vision for object recognition towards full automation. This would help your grandmother crank out high performance parts in her garage.
