Finishing
madCAM combines two strategies for finishing. To get surface smoothness with high tolerance the cutting depth should be as constant as possible. madCAM automatically separates surfaces that are relatively horizontal and vertical respectively. The limit between vertical surfaces and horizontal surfaces is set with an angle measured normal to the surface.

Z-level Finishing

Planar Finishing

The vertical surfaces should in most cases be machined before the horizontal surfaces, because these can be machined from the highest to the lowest level with a constant cutting depth (water line). The constant cutting depth gives a smoother cutting, with less vibration which results in better surface smoothness. Additionally, this method of cutting material from the highest to the lowest level, will prevent the shaft above the cutting length of the cutter from colliding with the un-machined material during machining of bottom surfaces.

madCAM automatically calculates approaches and retracts for each toolpath. The approach also includes a ramp to minimize cutter wear.

Z-level finishing Smooth Corners option
There is an option for sharp or smooth corners for Z-level finishing. If the cutter can't reach corners on the model due to cutter size, it will normally produce sharp corners on the toolpath. The smooth corners option will create fillets at those corners and make it smooth even when cutting those areas.

Planar finishing Blend  option
There is an option for blending when joining the toolpath curves for Planar finishing. This makes a smoother motion when cutting.
