Taper & Land

Taper & Land

Thing's that will be covered in this section.

• Creating land & taper features from solids

• Creating land & taper features from line/arc data

From the menu select file > Open

Open the file - TaperLand.wkf

Select Machining > CAM Navigator from the menus at the top of the screen, right hand click on Model manager and select run recognition

You will notice that there is more than one Setup in the CAM Navigator, this is because the automatic feature recognition works in X, Y and Z planes for use on machines with indexing heads.

In general, Wire EDM operations are only created in the Z plane so the operations in the first two `Setup's' can be ignored.

Note: If you wish to avoid multiple setup's being created you must first select `Add setup' from the Model manager (right hand click) then right hand click anywhere in the graphics window, a `Setup' will be created in the CAM Navigator, selecting `Run recognition' from here will then only look in the direction of the setup.

From the Cam Navigator, highlight the `Tapered pocket', right hand click then select add operation

The system will now open the Operations dialog box. In the Operations window, select Wire erosion operations, and on the right hand side select Land->Taper and click the OK button.

Two new operations will now appear in the `Wire' tab of the CAM Navigator, they will be put into a `Group' to indicate that they are both associated with the same aperture, one of the operations will be the tapered part and the other will be the land part.

Taper & Land from Line/Arc Data

From the menu select file > Open

Navigate to the following location and open the file -

C:\Visi19\Workf\Sample\wire\TaperLandLineArc.wkf

Select Machining > CAM Navigator from the menus at the top of the screen, right hand click on Model manager and select `Add tapered manual feature', pick the central profile and Ok the `pick a profile' dialog.

Enter the values shown in this dialog and select Ok

You will then be prompted to select the direction of the feature (Down=land at top, Up=land at bottom), hitting the spacebar will reverse the direction and right hand click on the mouse will accept.

Note: The imported profiles were drawn at Z0, so if the resulting feature is `land at top' the feature will have its top at Z0, this will not affect the NC output but if you prefer, you can move the profiles to the required Z thickness prior to creating the feature.

Make sure the arrow is pointing down and right hand click the mouse, the feature will be created and placed in the CAM Navigator window

Right hand click the feature, select `Add operation', pick the wire erosion operation, select Land->Taper then Ok

Two new `Grouped' operations will now appear in the `Wire' tab of the CAM Navigator.

This concludes the Taper & land section
