Fabrication Techniques


 * Sawing
 * Drilling
 * Laser Cutting

Tolerances
With any manufacturing technique you can expect some tolerances. For example laser cutting a part will be more accurate (0.1-0.2mm) than hand cutting a part (1-2mm). Try to consider this when designing your robot by:
 * Making holes slightly larger (0.1) than they need to be when bolting parts together to account for errors in hole placement.
 * Allowing good clearance on parts that may clash with each other (1-2mm)
 * Allow parts to be tightened using adjustable fixings such as bolts
