Abstract:
A compact, transportable computerized apparatus for designing sheet-metal fittings commonly used in the ductwork of ventilation systems. The apparatus is intended for use directly by sheet-metal workers at a job site. Designs for fittings are made one at a time with hardward and software that provide designs in real-time. The software includes coded instructions for real-time computing of patterns for boxes, elbows, transitions, and jumps. The software also includes coded instructions for computing elbows in the range of 0-90 angular degrees and for computing square throat radius elbows. The apparatus can be used with standard size metal sheets or with non-standard sheet metal scraps.
