BEND SEQUENCE DETERMINATION:
• It focuses on determining an optimal bend sequence from the set of feasible bend sequences.
• A part with many bends has many feasible bend sequences. A feasible bend sequence refers to a
sequence without any collision during the bending process.
• A collision may be self or with tool or with machine parts. It is described in the figure below.

TOOLING LAYOUT ON PRESS BRAKE:
• Tooling layout implies determining the actual locations of all tools that need to be mounted on the
machine.
•
An optimized tool layout reduces the total travel distance of an operator during the process.

GAUGE POSITION DETERMINATION:
• Back gauges helps in placing the sheet accurately in position by providing support from the back
side of the machine.
• The position of back gauge for each bend need to be determined.
