Abstract
An computer-aided automatic design processing system for designing processes for the machining of parts includes a process design processing section for deciding a machining device, a machining mode, and a machining reference surface based on a parts model of parts to be machined and a data base for production, a forming and verifying section for forming and verifying a process plan based on the output of the process design section processing section, and a fixture processing section. The system is capable of performing the computer processing of a process plan and a fixture plan.
Claims20
A computer-aided automatic processing system for creating processes for machining of parts, comprising:
- part input means for performing input of a part model, said part input means inputting information as to shape and accuracy as said part model;
- process plan processing means, responsive to an input from said part input means, for processing a process plan;
- data base means, coupled to said process plan processing means, for storing data on a plurality of machining devices, machine tools, and fixtures for the machine tools,
- wherein said process plan processing means includes means for selecting a machining device, means for selecting a machining reference surface based on said part model, means for determining a machining mode based n said part model and said data base means for a selected machining device, and means for drafting and verifying a process plan based on outputs from said machining device selecting means, said machining reference surface selecting means, and said machining mode determining means;
- and
- means coupled to said process plan processing means for processing a fixture plan for each of said machine tools and for each machining attitude,
- wherein said process plan processing means selects a machine device on the basis of the part model inputted by said part input means, and the data base for the machine tools, and
- wherein said process plan processing means includes means for restricting a machining attitude based on information on said machining device and said part model,
- said machining attitude representing an attitude of a blank relative to said machining device and said machining attitude being determined after verifying whether areas of all parts can be machined under a candidate machining attitude.
A method of creating processes for machining of parts, comprising:
