CADCAMWorkflows

CADCAM workflows are the integrated processes that move a design concept from computer-aided design (CAD) to computer-aided manufacturing (CAM) to produce a part. They cover design, planning, simulation, and data management across engineering and production activities, aiming to maintain design intent while optimizing manufacturability.

In the CAD phase, engineers create precise geometry using parametric models, assemblies, and geometric dimensioning and tolerancing (GD&T). Features, relationships, and tolerances are defined, and version control or data management systems track changes. Interoperability with downstream CAM tools is important, often facilitated by neutral data formats such as STEP, IGES, or lightweight formats like STL for downstream workflows.

In the CAM phase, a manufacturing program is developed by selecting stock, fixtures, tooling, and machine capabilities. Tool libraries and cutting conditions are defined, and toolpaths are generated using strategies such as roughing, finishing, pocketing, contouring, drilling, or turning. The process typically includes simulation and verification to detect collisions and ensure stock removal meets specifications before production.

Post-processing translates toolpaths into machine-specific code for CNC or other manufacturing equipment. This stage may involve integration with factory software for scheduling, tooling management, and quality assurance. Feedback from inspection and measurement can drive design adjustments, process tuning, and parameter updates, closing the loop between design and manufacture.

CADCAM workflows support subtractive and additive manufacturing, with some systems handling both. Common data exchanges include STEP, IGES, and STL, while product manufacturing information (PMI) increasingly accompanies geometry to preserve manufacturing intent. Benefits include improved accuracy, reduced lead times, and better manufacturability, balanced against challenges such as data compatibility, licensing, and the need for cross-disciplinary training.
