Capability to manage any revolve surface as bottom of pocketSelect any kind of revolve surface and not only cylindrical or conical surface, as the behaviour is the same. The surface types are:
Here is a example with a CATTorus surface: Select and manage several continuous faces to define the machining sideThe selection of several continuous faces can define the bottom of the pocket. The automatic contour detection takes into account the set of selected faces, as the behaviour is the same as for one face. When defining the machining side for one of the selected faces, the machining side is automatically defined for all the adjacent faces. This input is not compulsory and the system computes the machining side based on the bottom selected. Note:
If the computed side is not what is expected, then select the machining side in the geometry tab page and specify the machining side. Based on the geometry, the automatic computed machining side is different as shown.
There is the option to specify the machining side by selecting the surface and verify the side in the work area. If not the one expected, then invert. Management of a Closed Surface of 360 degrees and Cutting PointA set of surfaces of 360 degrees is defined as the bottom surface. An optional Cutting Point is defined by you (similar to the definition of a Start Point). This Cutting Point must lay near one contour of the 360 degree surface.
Note:
The cutting point is ignored if it is defined near an island. Depending on the surface 360 complexity, the tool path compute may fail. The cutting point can help to solve the problem. The guide contour of the bottom must include 2 external boundaries which are the natural boundaries of the selected surfaces.
For surfaces of 360 degrees and for revolve surfaces (except cylinder and cone), it is not allowed to position the tool tip outside of the bottom surface. Therefore, overhang greater than 50% or a negative offset on the contour are forced respectively to 50% and 0. Automatic Collision Detection between the Tool Assembly and the walls of the Pocket and the walls of islandsIf the part is defined in the Part Operation, the collisions between the tool assembly (tool holder and tool shank) and the part is detected and solved automatically by modifying the tool axis lead angle or by creating linking motions. If the collisions cannot be solved, the tool path computation fails with a warning message. |
