Since the appearance of UG, up to now, nx12 version, machining module
There is no special command for linkage opening. In the process of practice
The vast majority of workpieces are rough with fixed shaft, but a few workpieces
It has to be coarsened by linkage, so the 2D to 4-axis winding cutter path came into being,
Although 2D to 4-axis winding tool path is troublesome, it is a composite technology
One step is to extract the profile curve, the second step is to expand the profile curve, and the third step is to extract the profile curve
Make 2D tool path, step 4: turn 2D tool path into curve, step 5: use multi axis
Curve driven tool path, each step is technical work, and different work
There are all kinds of problems in the process, which is enough for you to choke. Even though it is
In this way, but every UG master must master.
Although contour milling and sequential milling can be rough, they are only suitable for external milling
Shape regular shape, although the boundary drive has projection vector and cutter axis control,
But the boundary drive and linkage are passing by, only because the boundary supports 2D
Plane boundary, 3D boundary is not supported, as for surface drive, although the
Follow the periphery, but it doesn't follow the shape of the surface, it follows the surface's
UV direction.
Careful experts will find that there is no area milling for multi axis modules,
But the fixed axis has area milling, which can not only screw, but also follow the
It's a pity that the fixed axis can't control the cutter axis and projection vector,
Therefore, multi axis and area milling are connected, which makes the secondary development high
Hand provides a research idea, that is, milling the fixed axis area
Transplant in a multi axis module. If you transplant, it means 2D to 4
The axis winding cutter path is facing the dismounting.
The research process is too much for the experts of secondary development, which is also
Maybe Siemens engineers can do things with one environment variable
Unfortunately, Siemens engineers can't see the idea of this post because they
I don't want to wander around the forum, and they don't know Chinese. |
