Abstract:
1. A method of preparing an estimate for sheet metal working, comprising: storing data of bending lines and data of an associated processing time for the bending lines; storing data of holes and data of an associated processing time for the holes; preparing a three-dimensional view and a development drawing which realizes the three-dimensional view based on an orthographic drawing; detecting a bending line and a hole on a product based on at least one of data of the three-dimensional view and data of the development drawing; calculating a processing time of the detected bending line based on the associated data of the bending lines; calculating a processing time of the detected hole on the product based on the associated data of the holes; storing the processing time of the bending line and the processing time of the hole in a processing time memory; calculating a total processing time necessary to process the product by adding the processing times stored in the processing time memory; and converting the total processing time to a cost of processing the product in consideration of a cost per processing time.
