Dark see prostitute lay "  of Nao of Huang of earnestly of wash of  of Gui of  of ぜ  cut down spends  of ＝ of glad  lofty to spend poison of Mei of Song of pure cover with a straw mat of  of  of  of the whistle austral Lou of poisonous Lie of glad  firm frequency Jin of Chi Shangwei cut down  5 poisonous Chi Shangwei, because UG is high end three-dimensional design software, its oneself error is dinky, can ignor. 3.

In the procedure that theory of reference point of 2 the smallest radius is establishing substance of lathe tool of round form figuration, used theory of reference point of the smallest radius. Reference point of the smallest radius namely workpiece profile is the smallest radius circle and the node that cross the cutting tool tool reference plane of workpiece axes. In system of lathe tool of round form figuration, close connection is form of section of section of law of model of workpiece of name a person for a particular job of control of the smallest radius, datum plane, cutting tool organic whole. If pursue a R, a is workpiece the reference point of the smallest radius of 4. Use database towel before cost of the character after horn is mixed, cross the smallest radius to nod A to found constructive datum plane 1 with 2, collect lathe tool of round form figuration from inside the database the structural data of 3, determine the position of lathe tool of round form figuration according to the position of reference point of the smallest radius next. Can make sure the structural dimension of lathe tool of round form figuration is standardized so. 3.

3 databases technology becomes the standardization that structure of form lathe tool designs to come true, the horn before this design system applied database technology to decide the structural dimension of lathe tool of round form figuration is mixed, hind horny cost. Before horn, hind the data in horny cost database and the workpiece material that the user chooses and its machinery function are had one to one correspondence relation, the workpiece material that chooses according to the user accordingly and its machinery function can be in the database the horn before locating extraction goes out, hind horn is worth (1) seeing a table.

Can collect data of cutting tool structure from inside database of dimension of structure of lathe tool of round form figuration, determine the axes position of lathe tool of round form figuration according to the position of reference point of the smallest radius next. Data table uses VC ++ .

The ADO (Active Data Object of NET, mobile data object) the database that direct operation Micmsoft Office Access founds. ADO is a kind of automation interface technology that is based on package object model 91, have the following characteristic: (Because 1) enclosed a lot of rock-bottom jobs, use ADO can simplify database visit, make the visit of the database more convenient, concise, shortened greatly the system develops time. (The data source range with applicable 2) ADO is wide, covered current and common data source type. (3)ADO allows to undertake approving updating () of method of use Updat Batch, can reduce computer burden greatly, raise a database to handle efficiency. (4) ADO is locating quickly, but expansibility, safeguard a gender to wait easily square and have Nextpage3 of distinct advantage 〕 .

4 modular design technology is modular the design that the design is helpful for a system and safeguard, because be of mutual independence between each module, realize pair of some module functions more easily accordingly change, won't affect other module at the same time. System of design of lathe tool of round form figuration shares data to collect, cutting tool is designed and output 3 module as a result (2) seeing a picture. Become independent each other already between each module, organic connection is together, fulfil whole system function jointly. 3.

5 parameter change design technology to change parameter design method to apply in diagnostic modelling design, make the feature has adjustability, can change according to needing to undertake adjustment at any time (the geometry that basically is aimed at a feature and develop attack information) , this is based on diagnostic parameter to change design method namely. Change parameter design method to apply in feature and diagnostic modelling, make diagnostic parameter is changed, realize parameter to turn model, the substantial information confluence of the flexibility that changes parameter thereby and feature is together. To lathe tool of round form figuration, the parameter that is based on a feature changes the feature that design even if uses UC to establish modular method, graphical dimension and certain tie condition mutual correlation, regard a design as conditional function graphical dimension, when design condition is changed, graphical dimension can undertake be updatinged accordingly subsequently. The design of figuration lathe tool is " design - detect - the iteration that designs " alters a course. When the design, after deciding dimension of a series to be worth through computation gets or be chosen from the database, the system will revise a figure automatically, restrain a condition according to what figuration lathe tool designs next, examine whether do dimension of a series of this figuration lathe tool of make choice of accord with design standard. Relapse ceaselessly so, the dimension of structure of figuration lathe tool that chooses to place oneself accords with total obligation condition.
