madCAM brings CNC toolpath generation into Rhino 3D, with editions covering 3-axis, rotary 4-axis, indexed 5-axis and advanced simultaneous 5-axis machining. It connects the design model with machining preparation in the Rhino environment, supporting work from conventional profiling and pocketing through to complex freeform surfaces.

The right edition depends on both the machine’s available motion and the machining strategies required. A three-axis job, rotary component and simultaneous five-axis part place different demands on tool orientation, stock handling and simulation, so those distinctions are central to choosing a suitable workflow.

Develop Toolpaths Around the Rhino Model

madCAM combines 2½-axis operations with 3D machining capabilities. Profiling, pocketing and facing address planar features, while roughing and finishing strategies support more sculpted geometry. This gives designers and machinists a route from the model’s overall form to the sequence of operations needed to produce it.

For freeform components, machining preparation involves more than selecting the finished surface. Cutter choice, stock, access and the intended finish all influence the operation sequence. Working in the Rhino environment keeps that preparation close to the geometry being manufactured.

Match the Edition to the Machining Task

The 3X edition provides three-axis machining, while 3Xtra adds remachining capabilities. The 4X and 4Xtra editions extend the workflow to rotary four-axis work, with remachining included in 4Xtra.

madCAM 5X includes three-axis, four-axis and indexed five-axis machining together with remachining. Its axis-of-revolution options also support simultaneous 4+1-axis toolpaths. The 5Xtra edition adds advanced simultaneous five-axis capabilities, making the difference between indexed and simultaneous machining important when comparing the two.

Machine Around a Rotary Axis

Four-axis functions include indexed 3+1 machining and simultaneous rotary strategies such as profiling, pocketing, facing and parallel roughing, with individual functions varying by edition. These allow machining to follow a component around its axis rather than treating every operation as a top-down three-axis cut.

Rotary machining can be useful for components whose working surfaces extend around a form. The available machine configuration and spindle orientation determine which approaches are practical, so evaluate the intended operations against the actual machine rather than its axis count alone.

Target Remaining Material With Remachining

Remachining functions address areas where a previous cutter has left material, for example where a larger finishing tool could not reach a smaller feature. In the relevant editions, madCAM can use a user-defined 3D stock model and generate further machining around residual material.

This supports a staged approach: remove bulk material with an appropriate tool, then use subsequent cutters where their size and access are needed. The higher-level toolset also includes options for processing or avoiding flat areas and smoothing toolpath corners to improve machine motion.

Review Material Removal and Tool Clearance

Material-removal simulation is available for three-axis operations across the editions, with rotary and five-axis simulation available at the relevant levels. Tool-holder collision detection is included, while machine-part simulation extends to four- and five-axis configurations in the corresponding editions.

Simulation helps assess the planned cutting sequence and the relationship between the tool, holder, stock and supported machine representation. Use it as part of a wider verification process, with accurate setup information, appropriate postprocessor configuration and controlled prove-out on the machine.

Evaluate the Workflow on a Representative Part

When assessing madCAM, choose a component that reflects your actual work: its freeform detail, stock shape, tool access and required machine motion. This gives a more meaningful comparison of editions than evaluating individual commands in isolation.

madCAM forms part of the CNC machining toolset covered on this site. The Rhino 3D plugins guide by discipline sets out what each tool covers, which ones need their own Rhino licence, and how the options fit together.
