Module of 1 foreword plot differs design of pitch milling cutter is professional very strong job, overmuch ground relies on the architect's quality and experience in traditional design, repeat calculation much, design cycle is long, and use a CAD, need to input a few necessary primitive parameter and structural demand only, the system can be inside very short time, make the manufacturing blueprint of cutting tool automatically. 2 computation programming to make full use of the advantage of all sorts of programming language, undertook mixture process designing. If be in,differ pitch carries milling cutter to optimize design part, use what can compile, grow the C language process designing at digital operation, the order form file that interface program develops one of tools by Auto CAD is written into; And when undertaking parameter transforms plot carrying milling cutter, use the AutoLISP language that embeds inside Auto CAD to write etc, finally, join them effectively with union, formed have friendly interface, computation to handle rapid software package, its structure flow is shown 1 times like the graph. Graph 1 differ does pitch carry flow chart of structure of milling cutter CAD to pass theoretical analysis and test result to make clear [1]: ? Bad lame Xi mansion of firewood of smile of of aspic of car of bring a case to court provides dinner for of of Guo of Gorgon euryale of δ of wooden tablets or slips for writing of a surname of nest of Ji of predestined relationship collect mires Yi of of Yu of garden of Shi of Wen of of ィ of Gu Meng of Mao of wall of Kang of Nuo of bamboo-plaited basket or suitcase of the She nationality 3 hold pulls Jing Huailai of enough of Mao of superintend and director of car of bring a case to court, whole computation program is woven by C language and become, program of whole design computation comprises by 3 module: 1) differ the horn between tooth of pitch end mill optimizes design module; 2) scale carries module of graph of spectrum of force of milling cutter milling; 3) angle of cutting of upright milling cutter changes module. Pass 3 module computation, the system writes computation into text file to stock disk as a result, enter Auto CAD system according to flow next, if the graph is shown 2 times,its design computational circuit. Graph the horn between tooth of 2 end mill optimizes design flow chart of 3 databases build a root to seize document [when 2] designs Duan Xi knife, outside dividing the basic parameter with necessary input, undertake as calculative, search public errand of exterior surface roughness, dimension, form from inside all sorts of chart at any time according to need even the structural data such as the relevant data such as tolerancepublic errand, fits tolerance and undercut, chamfer that hold bit, in the program these data are written into data file, take with offerring the computer to be read at any time. After 4 interface programming carries milling cutter to design computation to finish, computation the result stocks data file, after its computation program ends, enter plot order, start Auto CAD to enter plot state namely. Because C language and Auto CAD cent belong to different system, accordingly, how contacting both together is one of crucial technologies of this software. We use the interface program that the order form document that AutoCAD offers writes, solved successfully join to the transition of plot program from design program, program detailed list is as follows: 1 (makes new plan) graphical file name (but default) (Load " plot file name " ) load plot program) plot program (moving plot program) file of afore-mentioned order form is called by the batch processing file of DOS, its format is: ACAD X< commands group file name>Such, the system enters AutoCAD smoothly, can run plot program directly. The implementation that 5 parameter transform plot this systematic parameter changes plot to the program is woven by the AutoLISP language that embeds inside Auto CAD system and be become, autoLISP language provided function of a COMMAND for the user, finished the interface of AutoLISP and Auto CAD through COMMAND function, this is the only way that realizes to call Auto CAD command to have plot in AutoLISP program. AutoLISP program numerates put have differ the data in the text file that pitch carries milling cutter to design computational result, through necessary processing, call the command such as LINE, PLINE, CIRCLE, ARC by COMMAND function next, graph of substance of knife of scale Duan Xi and dimension line and pursue a frame line; Through calling TEXT the command tags all characters on requirement of dimension text, technology and graph face to wait, a few functions perfect the other of language of AutoLISP of final have the aid of finally the graph edits, form differ thoroughly pitch carries milling cutter blueprint, its are main the process is shown 3 times like the graph. Graph 3 differ pitch carries milling cutter graph to edit flow chart to differ after pitch carries the hypostatic graph of milling cutter to generate, the system stops in the COMMAND of Auto CAD to command condition falls, can save file to disk right now, also can convey the graph graph plotter, scale is generated differ pitch carries milling cutter job to pursue. 6 last words this system moves on 386 above micro computer through, supportive software is DOS6. 22, TURBOC2.

0 wait, this software can realize F80mm ～ F500mm to wait for 9 kinds to differ on personal computer the CAD that pitch carries milling cutter, the design of cutting tool from the input primitive parameter arrives to show on screen complete blueprint needs 3 ～ 4 minutes only, hundreds of times faster than traditional artificial design, shortened greatly the design is periodic, rose to differ the design precision that pitch carries milling cutter, reduced the design cost that carries milling cutter, provided strong design tool to enhance the market competition ability of the product, economic benefits is very remarkable.
