Design and engineering advancements also are a strong influence on CAD/CAM development,For example,

the advent of solid model kernel technology has allowed the sharing of data, features and machining strategies between products like never before,.Not only does the design work get easier with relational representations of part dimensions, but the CAM side also sees benefits. Those same features, diameters, lengths, etc. can all be automatically read by the CAM system—providing the user confidence in programming and automation. Once the machining parameters of a feature are “known” (i.e. the diameter, length, width, depth, type, size, etc.) this feature can be assigned a machining process (i.e. rough with tool 1, re-machine with tool 2, finish with tool 3) to cut at the machine, with confidence and efficiency. The technology behind feature recognition and knowledge-based machining would be perfect examples of the industry benefiting from this.
