  Computed radius The resulting radius as computed from the control settings. Amongst others the resulting radius is depending on the used tools in the bending process A large radius is meant to be bent with a special radius punch with large radius. If such a punch is not available, the bumping method can be selected.

• Page 48: Large Radius: Bumping

  3.4.2. Large radius: Bumping If a tool with large radius is not available, the bumping method can be chosen. With this method, a large radius in a product is obtained by a series of slight bends in succession. First you can choose the Angle Definition. The available definitions are: The default angle is the angle which could be programmed as standard.

• Page 49
  To apply the bumping method, the following parameters must be programmed: Central angle The supplement of the angle value to bend. Number of segments The number of segments in which the radius will be divided. The number of bends in this radius is the number of segments plus 1.

  4.4. Assignments 4.4.1. Introduction The Assignments are parameters with which the bend sequence computation is controlled. The assignments screen is opened from the tool configuration screen with the function key Assignm. Automatic bend sequence computation works with several conditions in order to find an optimum between a minimum production time, handling possibilities without product/machine and product/tool collision.

• Page 59: Cancel

  Cancel Leave the current screen without saving changes. Accept Save the changes and leave the current screen. 4.4.2. Assignments — general Optimisation degree Range 1-5. The number of alternatives to be computed for each bend must be entered here. The higher this number the more alternatives are to be examined by the control, so the longer the computing time will be.

• Page 60
  Punch length tolerance The punch length may be shorter than the length of the bendline. The maximum allowed difference between the punch length and bend length can be programmed here. Punch length tolerance may influence your bend sequence: if the length of a punch is shorter than the tolerance permits, it will not be accepted for a bend.

• Page 61: Assignments — Backgauge Possibilities

  4.4.3. Assignments — Backgauge possibilities Backstop against sharp angle allowed Specify if backstop may be placed against an angle smaller than 90°. No = not allowed Yes = allowed V0311, 4.9…

  Backstop-die, intermediate bend Set to allow if there may be a bend between the die and backstop. Selection possibilities: Permitted If unavoidable permitted: if it results that no solutions are to be found, than it is permitted Prohibited: never allowed. Edge tolerance In case backstop is against flat sheet an angle tolerance is allowed (deviation from horizontal).
• Page 63
  Lay-on backstop limit This parameter is useful in case the press brake has been equipped with backgauge fingers on a moving R-axis, having a so-called «lay-on» construction. When the length of the sheet at the backside of the machine is greater than this limit, the X-axis and R-axis positions will be corrected automatically so the sheet will rest on the backgauge finger.

  Method Select the required bending method. The control supports 4 methods: • air bend • bottoming • hemming • hemming & bottoming Bend methods: air bend The sheet is bent to the programmed angle by bringing the punch to the required depth. The control calculates the required Y-axis position to obtain the programmed angle.

  Bending length Length of the sheet between tools. Angle The required angle of this bend. This parameter only appears if angle programming is selected with the parameter ‘Angle sel.’ and the bend method is an air bend. Hem opening The hem bend can be made with a certain opening distance between the 2 flanges. The hem opening value will be used calculating the beam position in the hemming process.

  Gauge function The function key Gauge Func’ appears when the cursor bar is on an axis parameter. If Gauge Func is pressed, a window appears with several programmable parameters. These parameters serve to program the desired finger positions for a certain bend. The necessary axis positions that are necessary for this bend are calculated from the programmed finger positions V0311, 6.9…
