CADCAMbearbetning

CADCAMbearbetning refers to the integrated use of computer-aided design (CAD) and computer-aided manufacturing (CAM) to plan, simulate, and control machining processes. The goal is to translate a digital model into physical parts through controlled tool paths and machine instructions, typically for CNC machines such as milling machines, lathes, and advanced routing or drilling equipment.

The typical workflow begins with designing a part in a CAD system, producing a 2D drawing or a 3D model. The CAM phase then analyzes the geometry, selects appropriate tools, materials, speeds and feeds, and defines manufacturing strategies such as parallel milling, contouring, pocketing, drilling, or multi-axis operations. CAM software generates toolpaths and performs verification and simulation to detect collisions and optimize cutting conditions before production. After validation, a post-processor converts the toolpaths into machine-specific code (often G-code or ISO code) that can be executed by CNC equipment. The process ends with machining, followed by inspection and possible iterative adjustments.

Benefits of CADCAMbearbetning include improved accuracy, repeatability, and traceability, shortened lead times, and better optimization of material usage and tool life. It enables design-for-manufacturability decisions early in development and supports complex geometries with advanced machines such as 5-axis CNC systems.

Commonly used software ranges from integrated CAD/CAM packages to specialized CAM programs, often paired with ERP or PLM systems. Applications span industries like automotive, aerospace, mold making, electronics enclosures, and consumer products. Challenges include ensuring data integrity, managing tolerances, selecting appropriate machines and tooling, and maintaining up-to-date post-processors for different equipment.
