As someone experienced with CNC листогибочные прессы, I know how crucial bumping programming is for achieving smooth, gradual bends. In this step-by-step guide, I’ll walk you through the process of performing bumping programming on a CNC листогибочный пресс, ensuring you get precise results with minimal material stress. Whether you’re handling complex curves or fine-tuning angles, mastering this programming technique can greatly enhance your metal bending capabilities and production efficiency.

For big radius bends made with ‘bumping’ , it is possible to simple program the required data in a numerical program. First the operator can select the bend method:

0 = Airbend

1 = Bottoming

2 = Bumping

When selecting the bend method ‘Bumping’,  the operator can program the following parameters:

• Required bumping radius

• Total bumping angle

• The number of segments in the radius

The controller will calculate:

• The number of required bends

• The angles of the separate bends

• The backgauge positions of the separate bends

The first bend has an absolute backgauge position; the other bends will be treated as chained bends with relative backgauge positions.
