Increase as demand of market of the industry that weigh card, subsequently and come grow in quantity of order of car bridge product, order is new product perhaps goes mostly model product, need to undertake many product develops design and process design, process design develops design and production to produce the segment intermediate at the product, it is the bottleneck that the product designs production to make from development, it is important to have to the consign of the product restrict an element. Computer of CAPP(Computer Aided Process Planning) assists process design, those who point to is the work out of design of course of mechanical product, component and craft file, it is the bridge that join products plan and product make. 1 current condition (1) changes model the product is much, craft designs personnel repeatability job, amount of labor is big, craft file uses sexual difference. (2) craft file evaluates paper quality to change, big to paper waste, evaluation process is more troublesome. (3) craft file, tool codes, undertake judging having number according to encode regulation artificially, make mistake easily and inconvenience is searched. (Take up after file of 4) craft file the space is larger, craft file retrieves difficulty. (Term of 5) craft file is non-standard, design personnel has different technology to make a way differently. 2 technical data manage fundamental data: To the process name that craft file involves in work out process, model of product line name, machine tool, machine tool name, knife complementary, measure, the information such as tool clamping apparatus unites fundamental database is medium unified managing in the system. Man-hour management: Adopt man-hour ration card and craft file departure to weave, man-hour norm weaves the evaluation that does not affect craft file is released. Encode management: Encode of craft file, tool manages module to undertake coding applying for in uniform code. Automatic collect: Flow chart of basis product process, control plans to measure list to undertake automatic collect attributive installs to labour: Be opposite according to user demand for service in CAPP system user attributive undertakes installing. After the user enters CAPP system, the system undertakes automatically discriminating to the attributive of the user, use at assuring the security of information and validity, prevent lawful user intended or innocently visit of exceed one's authority, can prevent illegal user more inbreak. Card broadcast: The pertinent information live broadcast in product flow chart arrives in deputy card of control plan etc. The task divides the work: Product of craft branch basis adds craft line, undertake weaving craft file task undertakes dividing the work in the system, the task division of labor arrives corresponding section office. Craft of basis of section office controller member responsible product undertakes 2 times dividing the work, the member that the task division of labor arrives to be in charge of the craft of this product directly. Craft file annotate on: Craft file is in evaluation node, annotate on undertakes to craft file in annotate on interface, can undertake make a circle round one's name on a document submitted for approval to show that one has read it, insert the annotate on casing of different figure and literal description. Typical craft uses: It is typical craft to comparing the craft of the model to put, use directly when staff technology file come over, undertake modification on the foundation of typical craft, shortened staff time. 3 craft file edits 3.

The work out of the 1 craft file that does not have likeness cultivates component node to establish procedure in product structure, procedure cent is: Machine add procedure, procedure developing solder, ship-fitter art regulations, besmear installs the procedure, procedure that install solder, clean procedure; The card that place of editor craft file requires is included in regulations, add in regulations advocate card, advocate card is product process flow chart, information of the process name in card, equipment, clamping apparatus all calls the news in unified foundation library. After editor of card of product process flow chart is finished, insert control to plan card, use data broadcast function, advocate card news broadcast arrives in control plan. After control plans card work out to finish, watch of examination of plan of watch of examination of reorganization process flow chart, PFMEA, control, insert a knife complementary, measure, clamping apparatus has pool with collect function, in the knife complementary, automatic collect be sent on a diplomatic mission uses quantitative list in card of measure, clamping apparatus. 3.

The node of component of tree of structure of craft file product that 2 have likeness is used through typical craft file build craft file regulations, undertake modification on foundation of this craft file, new craft document is finished in the work out inside very short time. 3.

The 3 products that clean craft file to weave one cleans a line to be able to clean different sort, but its cleaning craft file is identical, have craft document staff, government according to component, with respect to meeting existence a line has many similar technology, the structure that cleans a line is built in the system in the light of this kind of circumstance, according to the work out that cleans a line to have craft file and management. After 4 craft file evaluates craft document staff to finish, technological process of the evaluation that start, condition of basis craft file chooses appropriate evaluation technological process, in evaluating flow node the choice evaluates personnel, refer evaluation. Evaluate each node to be able to undertake written instructions, make a circle round one's name on a document submitted for approval to show that one has read it, annotate on to craft file. Written instructions won't undertake to craft file any change processing, just show annotate on content from view, facilitating organizer has craft file change processing. After craft file evaluates node to pass, be in reference room file, data member whether does judgement accord with requirement of craft file file, accord with file to ask to have file in CAPP system, print craft file to allot. Norm of the man-hour after 5 man-hour norm weaves craft file file is finished member get job of work out man-hour, man-hour norm personnel builds man-hour ration card, the system draws product process flow chart automatically from inside corresponding craft file in pertinent information, undertake man-hour norm weaves, the work out is finished use collect function to have automatic pool to man-hour. 6 CAPP and other information system are compositive CAPP system is compositive adaptability is strong, convenient, but as compositive as PDM, ERP, MES, undertake butt joint of data of norm of information of BOM structure, craft, man-hour. 7 obtain the result (bugle call of 1) basis plan, clean a line very search a craft file to undertake examine and be modificationed from inside the system conveniently, saved go the reference room borrows read craft file time. Use through typical craft file, undertake be modificationed simply producing new craft document, shortened product process development cycle. (2) craft term received a standard, procedure is modular make craft file weaves farther standard, improved quality of craft document staff and work out efficiency. (3) raised maneuverability of craft file encode, tool encode, much person is being nodded differently can undertake coding operating at the same time, each other is not affected. (4) arrives in the extraction in craft card in original tool management and ERP system relevant data, ensure consistency of different platform data, saved cross platform to search data time.
