![]() ![]() Precision machined parts in airplanes experience less wear and tear and will last longer, increasing safety and reducing maintenance requirements. When the part is a titanium ball-and-socket joint that will be surgically implanted to replace your worn-out hip, a high-precision fit can make all the difference to your future mobility and comfort. The resulting computerized numerical control (CNC) machine was a flexible, programmable device for grinding and cutting tools and dies used in wood, metal, ceramics, plastics and composites cutting operations.ĬNC has increased the precision of machining operations so that parts can be produced with vanishingly small tolerances for a better fit. They had an idea to upgrade existing numerical controlled (NC) tooling machines with hardwired logic by connecting them to a $4,000 AUD “minicomputer” that stood about 5 feet tall. Pat Boland was a 25-year-old electrical engineer in 1974 when he co-founded Australian Numerical Controls and Automation (ANCA) with fellow engineer Pat McCluskey in Melbourne, Australia.
