Bevel unit vs. BIBER
Gantry cutting systems with bevel unit |
Robot cutting system BIBER | |||
Bevel shapes | V possible | V possible | ||
HY partly possible | HY possible | |||
X partly possible | X possible | |||
K not possible | K possible | |||
Flat chamfers | Not possible | On top up to 30° At bottom up to 20° |
||
4-fould chamfers | Not possible | Possible | ||
Processing time for simple chamfer geometries | Faster, as the part can be cut out of the board ready for use | Slower due to double handling | ||
Processing time for challenging chamfer geometries | Rework may be necessary | No rework regarding angle, bridge dimension, fitting accuracy | ||
Cutting time | Slower, because e.g. HY has 2 long cuts through the entire plate | Faster, e.g. HY: 1 long cut (pre-process), 1 short cut (chamfer length) | ||
Accuracy | Lower, for multiple cuts | Higher, as inaccuracies are measured and corrected. E.g. no 90° cut from pre-process is included | ||
Narrow Radii | Not possible | Small geometries are possible due to the better mobility of the robot, e.g. countersinkings | ||
Material thickness | Smaller material thicknesses are possible, as you always have to cut through the entire plate. | Larger material thicknesses are possible, as only the effective component size has to be taken into account. | ||
Material consumption | The material consumption is higher for bevel cuts through the entire plate. | Material consumption is lower because only the effective component size has to be taken into account. | ||
Cutting range | Due to the gantry design of the machine, large component sizes are possible. | Since the robot has a limited range, only cutting widths up to 3 m are possible. | ||
Chamfers on all sides of the component | Not possible: at least one side of the component has to be connected to the plate during chamfering. | Possible: components with bevels on all sides can be chamfered |
BIBER - THIS IS HOW YOU CUT CHAMFERS
