Estimating the term…
When a sheet metal is sandwiched between a punch held by a punch holder and a die held by a die holder to bend the sheet metal at a set bending angle by moving the punch toward the die, a stroke calculation unit calculates a stroke of the punch for bending the sheet metal at the bending angle in consideration of a spring back amount of the bent sheet metal. A bending load calculation unit calculates a bending load required to bend the sheet metal at the bending angle. A punch deflection amount calculation unit calculates a punch deflection amount according to the bending load. A punch holder deflection amount calculation unit calculates a punch holder deflection amount according to the bending load. A depth value calculation unit calculates a depth value by adding at least the punch deflection amount and the punch holder deflection amount to the stroke.
A press brake control device, comprising an NC device wherein:
A press brake control method, executed by a control device that controls a press brake for bending a sheet metal by sandwiching the sheet metal between a punch held by a punch holder and a die held by a die holder and then moving the punch toward the die, the press brake control method comprising:
