  • Page 28: Large Radius: Bumping

    2.4. Large Radius: Bumping To make a bend with a large radius, the control uses the bumping method. With this method, a large radius in a product is obtained by a series of slight bends in succession. To program such a bend, you must program the following parameters: radius = the desired radius segments = number of segments The number of bends in this radius is the number of segments plus 1.

This pro- duction time depends on the positioning speed of the axes and the product handling times. Turning of your product takes production time. This time depends upon the length and width of your product.
