TorchTableModularTooling

Overview

The CNC_Torch_Table consists of a stepper-motor-driven CNC XYZ table intended to carry a plasma torch or oxyfuel torch for metal cutting. However, additional functions could be supported by the same table my substituting or adding to the torch head.

Light-duty (limited cutting force) cutting of wood, plastic, foam materials.

Marking Function

(From email ChuckH 17:15, 3 December 2012 (CET))

"Plan C": use the CNC table as a marking machine for layout, and do our cuts by hand.

I suggest using round soapstone, like http://www.atlweldingsupply.com/Round-Soapstone-Gross_p_254-1393.html, in some sort of spring-loaded holder. Alternatively, silver sharpies http://www.amazon.com/Sharpie-Metallic-Permanent-Markers-39108PP/dp/B00009RAX4

Although this is clearly not a final solution, it actually has certain advantages:

1. Does not require completion of torch height control and plasma supply interface on torch table for Dec 18 CEB build
2. We can mark much faster than we can cut
3. Marked parts can be hand-cut in parallel, shortening overall production time
4. Glitches in CNC table operation are unlikely to cause ruined parts (i.e. we can catch them before we cut)
5. We can place layout marks for other operations besides cutting (e.g. center marks for drilling or punching)
6. We can mark index number and orientation on each part
7. Allows us to prove out most of the torch table toolchain on this build.

Either the soapstone or sharpie will wear down and start making broader, possibly off-center lines. The soapstone can be pointed much like a pencil, while the sharpie you'll just throw out. Probably get a bunch of both and see how they perform.
