Axial turning helicoidal contouring (with C axis)
Menu: Turning | Axial turning | Helicoidal contouring
Links:
Make an axial helicoidal contouring using a rotative tool. Unlike a traditional contouring operation, carried out at a constant altitude, the cycle contains a simultaneous descending move all along the tool path, so that tool wear is reduced.
The positioning of the part and the machining is done with the C axis (Spindle) and NOT with the Y axis even if the machine tool has one.
The topological analysis engine searches for all sides adjacent to the selected side, so that a closed path is defined, when possible. Detected sides are automatically and vertically extended to the stock model’s lowest and highest limits. The system offers a point in the middle of the user selected side as the contouring operation’s starting point. This starting point, the type of lead in and lead out moves and the various descending modes can be modified when the operation is defined.
The algorithm also controls 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.
A contouring operation implies descending moves into or outside the material! 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.
The helicoidal contouring mode assumes that the tool path is closed.
Activate the default Wcs of the part if it's not the current one.
Select the face to machine.
Select the tool to use for the operation
Specify the different parameters in the tab dialogue box which appears.
Enter the comment which appears on the machine block listing meant for the NC operator. This comment will also appear when the user wishes to take a look at or modify an operation, using the Operation/ Operations manager function.
Eventually, enter a codified remark which will be interpreted by the post-processor, in a specific manner predefined by the user and the post-processor redactor.
Validate entries made into the dialogue box by clicking on OK.
