Operations for 2/2.5-axes milling

The peculiarity of 2D and 2,5D processing operations – non obligation of presence 3D model of the part. The work task, and also the part, the billet and rigging may be formed only because of such curves, and in some cases because of points. The use of surfaces under the certain circumstances also possible. For example, the operation of Hole machining on adding the holes it assumes in work task the use of cylindrical surface. Or in the operations of processing curves in the work task is possible to indicate “walls” – i.e. such surfaces which are perpendicular to the plane of the current operation of machining. Besides, in all the operations, where the setting of curves, the edges of 3d model may be used as curves.
