The stand or fall that the car enclothes a mould to design is to restrict a car truckload the bottleneck of quality, the car enclothes a mould structure to if what show,be designed. The article basically discusses a car to enclothe a mould standard component of the library establish a procedure. The car enclothes a mould standard component the content that the library basically includes 4 fields: It is to establish general standard spare parts of instrument of the library of GB fastener spare parts that graph library includes to open, commonly used analyse designs a library; 2 it is to build enclothe a mould to design special plan library to include pattern plate, mould bases, tripper, oriented device to reach all sorts of auxiliary unit designs to wait; 3 it is to build design data-base to include GB dimension to be tagged automatically, GB dimension public errand is tagged automatically, GB form tolerancepublic errand is tagged automatically, GB surface roughness is tagged automatically, line of assembly drawing jackknife is automatic disappear concealed; 4 it is typical structure design, design of the punch design that if pull,extends a pattern, sunken model design, the circle that approach a limit. The article designs main introduction pattern medium standard component library establish a procedure. A dialog box reachs the part that forms by certain order in casing to comprise by a casing. In the dialog box generate and the user is changed in stating, call the component commonly accuse. Each dialog box is by a few base encoffin arrives on the parameter of pattern plate is changed set (plan make Shi Jian want Huse of Piao oily ground.

HttJ, : / / Wwwxnki-net (2) software environment 0 use AutoLISP language to develop. AutoLISP language is one kind embeds the programming language in AutoCAD interior, it is LISP language and AutoCAD the child of organic union. AutoLISP is AutoCAD in powerful tool, use AutoLISP to be able to found brand-new AuU-CAD command, these command the clew information that can use indication him user, make decision-making, finish in-house computation, the hypostatic part with complex scale, revise existing AutoCAD to command in order to complete special operation. In addition, autoLISP still provided the interface function with the outside, pass interface, can make the function of AutoLISP outward and outspread, make a lot of problems that solve hard with AutoLISP function alone become a possibility. Accordingly, can say AutoLISP is the optimal tool that builds the CAD software that belongs to him user truly to use a program. Of standard component library build. It can make CAD system has function of seesaw pattern plot not only, and still have automatic plot function. Use parameter to change the special design system that designs resort development, can make the disengagement in designing personnel to work from a large number of trival plot comes out, raise design rate greatly, reduce the memory of information to measure. The parameter of project blueprint changes a structure but with programming the program structure analogy of language AutoLISP language, the program of any AutoLISP is by finite case array is become; Any project blueprint are to decompose change a plan for finite parameter yuan. Below AutoCAD environment, parameter changes a plan yuan it is the graphical function that defines by AutoLISP. AutoLISP language can describe a plan optimally yuan develop attacks relation, give out graph yuan appearance, position and likely control feature parameter. Accordingly, can weave to some project blueprint pursue specificly yuan of combination. The article is aimed at the general part with the widest application in mould design, wait like bolt, bolt, nut and the special purpose parts in enclothing a mould to design, the pattern plate below as above, mould bases, oriented device, use parameter to change design method. The design is changed in parameter in, oversight in assembly drawing omissible pours wine cup, can simplify so the design that parameter changes. In be being designed with respect to the mould below, explain. If we want next pattern plate of scale, want to decide a few regulation above all, how convey this graph in order to decide. This matters with the architect. A basic regulation is: A graph is tagged in the dimension on each direction must close, do not have redundant dimension already namely (can derive dimension) , the dimension that did not lack again (dimension catenary did not close) according to this principle, the dimension that can tag this graph into place to show concerns, it reflected the concern between the dimension of composition of a picture of this kind of knot, among them dimension parameter 05, red, say, 5, reach, H, D) call the independence that makes this plan parameter or variable. Parameter changes a program to become independent with this kind namely variable regards the entrance as parameter, according to different dimension variable the value makes corresponding figure. Reach its to range way. The user also can define the size of each element in DCL file. Nevertheless, although use a measurement that does not appoint an element, autoCAD also can be an element to set value of a default according to the current situation of each platform. Of this standard component library build use AutoLISP to write. CNC Milling
