Profile Machining

3D contouring allows the user to machine a complex surface by following defined profiles, using two different methods. With the first method : the profiles’ altitude are respected. The second method involves machining is projected on the part. This mode also allows the creation of engravings, using the same method as for the corresponding 2D function..

Single Surface Machining

Chained sweep machining and 5-axes sweep machining functions allow the user to machine a complex surface, by following the iso-parametric curves it is made up of. To date, these modes are the only ones ensuring maximum quality for a part, relating to the state of its surfaces. Therefore, sweep machining operations are mainly meant for finishing operations. It is possible to extend sweep operations’ functions to nearby surfaces, provided they are tangential to one another and that the continuity of their iso-parametric curves is ensured..

Multi Surfaces Machining

This category contains the following functions :

• Quick Roughing

• Roughing by Steps

• Plunge Roughing

• Re Roughing

• Planar faces machining

• Z levels

• Parallel Plane

• Constant Scallop

• Super Finishing

• Projected Pocket Path

• Material Left Removal

• Reference Tool material left removal

• Pencil Machining

The above mentioned functions all take the part as a whole into account. Nevertheless, the user can limit the machining areas in order to only perform machining operations that are absolutely necessary and/or to obtain maximum use of the various calculation algorithms. Rework operations implicitly use limitation curves.

Z levels, Parallel plane and scallop height functions can all be found in a dialogue box called finishing machining operations..

The examples below show 3D contouring operations onto the surface or profile machining, an iso-parametric sweep machining operation, as well as a parallel plane technology operation..
