2.2 The main technical indicators of the system (1) enable the basic process information of the parts input by Jiedi, and extract the process drawings from the AutoCAD graphic files;
(2) Prepare a standard heat treatment process for each part in the “100% WYSIWYG†interface around the heat treatment requirements of the parts;
(3) Realizing the information storage and reuse of the heat treatment process specification;
(4) Support pre-browse function before operating the process specification;
(5) Support the printout of process cards.
3 <br> <br> workflow system of the present system is modular in design, the workflow shown in Figure 2.
Figure 2 System work flow chart
(1) The basic information of heat-treated parts includes: part number, part name, product type, process version, number of process pages, process page, commission unit and process number.
(2) For quenched and tempered steel, spring steel, martensitic stainless steel and rolling bearing steel, the requirements for fire suppression include: heat treatment hardness, maximum thickness or condition thickness of parts, residual machining allowance of parts, fire-fighting tooling, furnace loading, inspection Hardness tester, ratio of hardness checked, and other inspection items.
(3) Carburizing heat treatment requirements include: acceptance items before carburizing, depth of carburized layer, surface hardness after carburizing, amount of carburizing and charging, hardness tester for checking hardness, ratio of hardness inspection, and other inspection items.
(4) Nitriding heat treatment requirements include: acceptance items before nitriding, depth of nitriding layer, surface and center hardness, nitriding inspection category, hardness tester for inspection hardness, ratio of hardness inspection, and other inspection items.
4 Conclusion <br> <br> describes a heat treatment system for an aircraft hydraulic CAPP attachment, a user interface may utilize finished, easy to complete the process design from a series of process management functions. The system can greatly improve the work efficiency of the heat treatment process personnel, shorten the production preparation time, ensure the standardization and consistency of the process design, and promote the standardization of the heat treatment process, thereby improving the quality of the product and the economic benefit of the enterprise.
