## Abstract

An apparatus for proposing bending sequences and bending tools for a metal plate part includes system for storing a development plan of the metal plate part; system for detecting a plurality of bending sequence proposals which make it possible to manufacture the metal plate part based on the development plan, and bending tool proposals used in each bending process of each bending sequence proposal; and system for displaying the plurality of bending sequence proposals. Such display includes information showing the stage numbers in each bending sequence proposal.

## Claims

### Claim 1

A method of detecting bending sequences and bending tools, comprising:
storing a development plan for a metal plate part having a plurality of bending regions;
inputting a maximum number of bending sequence proposals to be detected;
detecting up to the maximum number of bending sequence proposals based on the development plan;
detecting bending tool proposals used in each bending process of the detected bending sequence proposals; and
displaying the detected bending sequence proposals and the detected bending tool proposals;
wherein the detecting the bending tool proposals includes detecting interference between the bending tools and the metal plate part for each mounting state of the bending tools on a bending machine.

### Claim 2 (depends on 1)

The method of claim 1, wherein the mounting state of the bending tools includes a front mounting state and a rear mounting state.

### Claim 3 (depends on 1)

The method of claim 1, wherein the detecting the bending tool proposals is performed in the order of punches, dies and die holders.

### Claim 4 (depends on 1)

The method of claim 1, further comprising inputting a selection priority order of application tools.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
determining whether a first bending tool of a first bending operation can be used in place of a second bending tool of a second bending operation; and
replacing the second bending tool of the second bending operation with the first bending tool when such replacement is determined to be possible.

### Claim 6 (depends on 5)

The method of claim 5, wherein the first bending tool is longer than the second bending tool.

### Claim 7 (depends on 5)

The method of claim 5, further comprising determining the arrangement of each stage on the bending machine.
