Roughing rotary operation
Roughing rotary is a 4 axis toolpath that removes the workpiece material layer by layer. It is similar to the Roughing Waterline except that the machining layers are not planes, but cylinders around the rotary axis.
The rotary axis is defined by its origin and direction. You can easily set the desired parameters of the rotary axis both in the inspector and with the mouse in the graphic view.
The job zone is defined by:
The depth step can be set as an exact value as well as the number of layers.
The machining step defines the maximal distance between the machining passes in a layer.
Currently three strategies are available.
The circular strategy generates passes around the rotary axis that represent 4 axis arcs.
The linear strategy generates passes along the rotary axis that represent linear cuts. The angular step-over between passes on each layer is the same, what means that the real step-over gradually decreases when approaching the bottom layer of machining
The Spiral strategy generates helical passes. The pattern is well suited for machining parts like screws and impellers.
