Removes all material found between the contour representing the finished part’s external sides and the stock model’s external contour.
TopSolid'Cam advises a certain number of passes in Z, relative to the quantity of material to be removed and the cutting conditions of the tool called.
The contour milling cycle controls simple and complex contour sides. The user specifies a side that is automatically extended to the stock model’s internal limits. The finished part is considered as an island to be protected when the system machines the stock model. The algorithm controls the corners for which the minimum radius is smaller than the tool radius. In such a case, TopSolid'Cam generates rest material that will be automatically recognized by subsequent rework machining operations.
When machining parameters are entered in the dialogue boxes, the actual machinable area is visualized through an interactive hatching.
A contour milling operation implies descending moves into the material! However, several descending modes are available, relative to the tool the user chooses. For a vertical descent into the material, in rapid or work feed rate, the user can define a descent point or use one offered by TopSolid'Cam.
Topologic mode
Specify the model’s side to be machined.
Validate the “Spiral contour milling” selection.
Choose the necessary tool for the operation.
This choice is available when the topologic analysis finds one or several vertical faces, outside the part and through the stock. This detection is made according to the current Wcs.
Automatic mode
Specify the profile on which a nibbling operation is to be performed.
Specify the side of the model to be created and on which the contour milling operation will be set or specify the altitude value with which the operation will be executed.
Choose the necessary tool for the operation.
The user can later click on the “Info” button to obtain information on the geometrical characteristics of the side to be created (surface area, minimum radius, total height, etc,).
