	The torch table is a computer-controlled device that can move a plasma cutter or acetylene torch. Plasma cutters and acetylene torches are devices for cutting metal. By attaching these to a computer-controlled arm that can move very precisely in any direction, we create a device that can cut metal into any shape you can imagine. This is very useful for making machine parts.		The torch table is a computer-controlled device that can move a plasma cutter or acetylene torch.

This is very useful for making machine parts.

			The self-replicability comes from the fact that the entire gantry and motion structure, minus electronics and stepper motors, can be cut out on the table itself.


	The table is readily adaptable to industrial duty routing. Accuracy is not sufficient for circuit fabrication. Cost of the table is about $1500 for materials, and we aim to produce these tables for an additional $500-1000 in labor costs for a total of $2000-2500.

	~~Our development log is [http://openfarmtech.org/index.php?title=XYZ here.]~~

	Here is a design that is based on review from the CAD_CAM and DIY CNC Yahoo groups as well as feedback from other sources. The drive is obtained with stepper motors and rack-and-pinion style direct drive with a 1" pinion gear. Using 425 in oz stepper motors, this allows for direct coupling and ~50 pounds of force delivered to move the gantry. Linear bearings and ball screws were replaced with rack-and-pinion drive due to cost considerations. Using direct rack and pinion drive, good accuracy is possible: theoretical 2/1000 of an inch for a 1 inch pinion gear with 1/8 stepping. The limiting factors will be straightness of the guide rail (1 1/4" cold rolled steel rod) and resolution of the pinion gear.
