Abstract

PURPOSE:To facilitate additional working of a die by generating additional data of the die in accordance with the interference quantity, when it is impossible to pass an interference check with regard to the die which has been set, and also, assuming the die which has been added, and subsequently, shifting to a generation procedure of bending data. CONSTITUTION:Whether a work interferes with a die or not is checked, one end of the work interferes extending from an interference start point to a bending end point, and an interference area is generated. When a machine and the die are set automatically or manually, and a bending sequence is set, an interference check is performed. In case it has been decided that no interference is executed in all bending processes, bending data is generated in order to execute each process. In case it has been decided that there is an interference, whether the die, the machine and the bending sequence can be changed or not is decided. In case the condition can be changed, the interference check is executed again under the condition which has been changed. In case the condition cannot be changed, bending data is generated by disregarding a fact that it has been decided that there is an interference, and simultaneously, the interference quantity is derived, and additional working data of the die is generated.

(Prior art) In recent years, in the field of bending, which is still manual work, in order to create bending data almost automatically, settings are made while simulating the actual bending state of the workpiece using a set mold. It has become common practice to automatically create bending data that determines the back gauge and the amount of mold movement for the mold and bending order that have been created.

Therefore, conventionally, based on the information that there will be interference, the operator would either change the bending order or the mold and create a new mold, or judge the interference m as a guide, cut the mold as appropriate, and try again to avoid interference. Checks are being carried out. In many cases, it is possible to avoid interference by changing the bending order or mold, but there are cases where it is not possible to change the bending order or mold to prevent deterioration of the product shape or bending accuracy. It is.
