Faced with your first CNC machining project and wondering where to start? Discover how 3D modeling software like BobCAD-CAM empowers manufacturers to design, simulate, and execute precision toolpaths with ease. In this week’s training spotlight, we dive into the essentials of 3D CAD-CAM—from wireframe extraction to advanced milling techniques—so you can streamline your workflow and elevate your machining results.
What is 3D Modeling Software?
3D modeling software is a specialized CAD-CAM solution for creating 3D geometry that drives CNC machining operations. It allows users to design parts as solids, surfaces, or a combination, then generate toolpaths that remove material to produce the final workpiece. Using this software ensures accurate and efficient machining, whether for simple or complex geometries.
2D vs 3D CAD-CAM: Key Differences
2D CAD Explained
When your geometry comes as a DXF or DWG file with points, lines, and arcs, you are working with 2D geometry or wireframes. These sketches drive 2D machining operations like pocketing, profiling, and engraving.
3D CAD Explained
When your geometry comes as IGES, STEP, or SAT files with rendered surfaces and solids, you are working with 3D geometry. This drives 3D machining operations such as roughing, semi-finishing, and finishing, allowing the tool to move in multiple axes for complex parts.
2D CAM vs 3D CAM
-
2D CAM: Limited to X and Y axis motion using sketches. Common operations: profile, pocket, engraving, facing.
-
3D CAM: Expands motion to 3-axis simultaneous cutting using surfaces/solids. Operations include Z-level, planar, spiral, adaptive, and flowline toolpaths for precise, efficient machining.
