3+2 AXIS ROUGHING:
Shorter run times and less wear on tools.
Tebis roughing involves removing stock from a user-defined blank plane by plane from top to bottom, thereby approaching the desired target geometry in a terraced representation. The virtual tracking function lets you see, as early as the program calculation stage, exactly what the part will look like on the real machine.
As early as the NC program calculation stage, Tebis generates the same intermediate geometries, plane by plane, that you get when machining with the selected milling tool in the real world. By doing this, the system continuously updates the original blank geometry. As a result, Tebis always knows how much material remains and where it is located, thus dramatically reducing idle travel and therefore also run times.
Intelligent algorithms also make sure that contour characteristics are gradual and gentle on the tool, enabling you to mill at very high feed rates. Depending on the tool contact, Tebis outputs different feed rates, reducing the feed rate when making a full cut for example. As a further advantage, continuous collision protection is run on current machining states and not only the target geometry to be achieved.
Material thickness analysis for efficient remachining
The intermediate geometries calculated by Tebis also provide information about the thickness of the material remaining on the target geometry. This function quickly, reliably and precisely finds the sites in the component that still contain too much material. And that makes possible extremly efficient strategies such as machining with large milling tools and high cutting capacity, coupled with remachining programs that are applied only to the areas where material still remains.
- The material thickness analysis localizes the areas (red) where too much stock still remains.
- The calculated intermediate geometry (left) is used as a new blank geometry for remachining.
- To streamline the roughing programs, you can digitize the blank casting and provide it as the blank geometry.
- A different tool orientation is ideal for machining particularly steep and excessively undercut areas.
- High-speed roughing, thanks to rounded, smooth and thus HS C-capable NC paths.
- Spacing the planes closer together breaks up the terrace representation.
- The material thickness analysis creates boundary curves for selective remachining in areas where too much stock remains.
