WORKING SYSTEM, DIFFERENCE EXTRACTING APPARATUS, CAD DEVICE, CAM DEVICE, PROCESSING METHOD PROGRAM AND PORTABLE STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a working system which can shorten a working period and to provide a method for working.

SOLUTION: A CAD unit 1 outputs shape data 11 to a difference extracting unit 2 on the mid-way stage. A difference extracting unit 2 outputs a difference between the shape according to each shape data 11 and the shape of a design stage before one stage as difference data 22 to a CAM unit 3. The CAM unit 3 forms a numerical control program based on this. A working unit 4 sequentially performs the created numerical control programs and processes to work a work piece. The respective units operate in parallel, and can thereby shorten the working period from the start of designing to the creation of the work piece.
