On this image, the surface is oriented for machining with a 4th axis aligned on Y and the toolpaths will produce a machining by turning once the Gcode re-wrapped around Y. If your 4th axis is aligned with the X axis then it will be enough to turn the surface unrolled by 90 В°.ДЄpply one or more 3D machining operations to this surface, making sure to set the machining boundaries so that the center of the tool reaches exactly the edges of the surface The goal is to prevent the tool from descend to the edges, which would make a groove in the workpiece at the junction of the two edges if the tool goes too far, or leave unmachined material at the join of the edges if it do not go far enough.Дepending on the selected scanning methode in the 3D machining operation, horizontal or vertical, and the orientation of your 4th axis on the machine, the machining can be done by turning (toolpaths perpendicular to the axis of rotation) or by bands, the rotary axis does not turn during machining (moves are parallel to the axis of rotation) By default, after unrolling, the resulting surface is ready for machining with a 4th axis whose axis of rotation is aligned with the Y axis of the milling machine. Position the resulting surface to match the orientation of your 4th axis. The Axial stepover represents the spacing of the measurement points along each 'band', expressed in current drawing unit. The higher the number of Angular Steps, more the resulting form will be detailed, here 360 steps will give 360 'bands' of 1 В° wide once the object unrolled. The Z min at -10 means that the plugin will test the shape up to 10mm below its axis, which is necessary here because some areas are lower than the axis of rotation. (and Stock Surface will also need to be 32 in the machining operation) so that the tool does not plunge into the material when roughing. In the case of this example, the 3D model is 50mm diameter, but I start from a rough piece of 64mm diameter (32mm radius) so I put a Stock radius of 32 in the plugin.

The source object can then be deleted to free up memory, especially if it is a very dense mesh. On this picture, the 3D surface in red is an unroll of the initial 3D object in gray. Unroll the 3D object with the Unroll 3D Model plugin, to get a surface machinable with a regular 3D machining operation on XYZ.

Alignment can then be achieved with the standard CamBam alignment feature.

(the green axis) for that, use the Numerical Move/Rotate plugin for example, or the built-in rotations functions of CamBam to turn the model in the right position. Open and position a 3D object to align its center of rotation with the Y axis of CamBam.

Unroll 3D object - Documentation WorkflowДЄs CamBam does not have a machining operation that manages a 4th rotary axis, the working process is as follows:
