Title:
MANUFACTURING PROCESS DESIGN METHOD AND MANUFACTURING PROCESS DESIGN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/014748
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable suitably determining a manufacturing process which includes a forging process and a cutting process for generating a desired shape. A forging target shape, which is the target shape of the forging process, is generated on the basis of the product shape (S2); on the basis of the forging target shape, the forging load of the press equipment used in the forging process, and the workpiece shape at a first time point, i.e., the workpiece shape prior to the forging process, a forging process plan involving one or more steps is generated, and an estimated workpiece shape is generated, which is what the shape of the workpiece will be after forging, based on simulation results of the forging process plan (S3); on the basis of the product shape and the estimated workpiece shape, a pre-correction NC program for a cutting step is generated (S4); the cutting cost of the cutting step is calculated on the basis of the pre-correction NC program, and the forging process plan in the manufacturing process is displayed along with the cutting cost in the cutting step.
