Torch Table Prototype II Design.

General Fabrication Product Ecology

The CNC Torch Table is a computer controlled machine capable of cutting two-dimensional shapes out of large steel plates. 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.

Status

CNC Torch Table II
Design is finished and prototyping is underway.
Zipped SolidWorks File Sketchup File

CNC Torch Table I
Prototyped and Tested in experimental production runs. Identified software toolchain as a performance bottleneck.

Design Rational

The following points have been considered throughout Torch Table development.

• Design ergonomic frame and motracks and gantry on it
• Stiffen frame design to accommodate router heads
• Perfect mechanical design for replicability to 1/32" over 6x12' area
• Research 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.
• Sketchup file In progress.

• Clearance to cut 4" square tube 20 feet long.
• Clearance to cut 6" square tube 10 feet long. (without removal of "ribs")
• Clearance to cut 10" square tube 10 feet long. (with removal of "ribs")
• Reasonable rigidity is prefered for the frame design. The level of rigidity should be decided on a quantitative basis, however for the scope of this prototype rigidity should always be considered on a qualitative basis at least.
