Embodiment
As shown in Figure 1, key step is as follows for the process flow diagram of the inventive method:
Step 1, collection are processed relevant tool-information to spacecraft structure part, form cutter community set.
Tool-information comprises: cutter classification, cutter model, material, specification, sword footpath, total length, sword number, bottom fillet, effective length, sword is long, handle footpath, cutter chief editor number, cutter right-hand man, clamping system, knife bar is outstanding long, handle of a knife interface size, handle of a knife type, tool cutting edge angle, handle of a knife knife bar size, interface diameter, Luo line specification, pitch, pitch shape, form of thread, blade shapes, blade relief, blade type, blade size, blade thickness, nose radius, cutting edge flute profile, chamfered edge angle, blade width, blade tool rest type, accessory, spacecraft model, structural member title.By above every composition cutter community set, cutter attribute is all from cutter community set.The static attribute that in certain class cutter, entity cutter all has and the identical attribute of property value is this class cutter.As the static attribute of milling cutter class: { cutter classification: " milling cutter " }.That in certain class cutter, entity cutter all has but dynamic attribute that attribute that property value is incomplete same is this class cutter, as comprise straight shank milling cutter, taper-shank cutter ..., the dynamic attribute of milling cutter class so: { handle of a knife type }.Cutter static attribute and dynamic attribute include attribute item and property value.The static attribute of similar cutter is identical with dynamic attribute, and the static attribute of xenogenesis cutter is different, dynamic attribute can be identical.
Cutter community set is extensible element as required.The dynamic attribute item number of cutter classification tree node is not limit, and on cutter classification tree, digging up the roots with static attribute and the dynamic attribute of outer other node of leaf node can not be sky.
Step 2, establishment cutter classification tree
A corresponding class cutter of node on classification tree, each node all comprises static attribute and two storage areas of dynamic attribute, stores respectively static attribute and the dynamic attribute of such cutter.Cutter classification tree constructive process comprises: 1. create classification tree root node, its static attribute be made as to sky, from cutter community set, select element (as: " tool type ", " cutter chief editor number " ...) and be made as dynamic attribute; 2. create classification tree two-level node, from the dynamic attribute of root node, select part (or all) subitem, data after assignment, as the static attribute of two-level node, select the relevant subitem of this class cutter corresponding to newly-built two-level node as dynamic attribute from cutter community set.As milling cutter class static attribute: { tool type: " milling cutter " }, dynamic attribute: " cutter chief editor number ", " material " ... .}; 3. create three grades of nodes of classification tree, from the dynamic attribute of secondary father node, select the data after part (or all) assignment, add the static attribute of secondary father node, form the static attribute (be in static attribute+at least one the father node of the static attribute=father node of the non-root node of cutter classification tree the dynamic attribute of assignment) of these three grades of nodes; In dependency set, select the cutter class coherent element corresponding with three grades of newly-built nodes as dynamic attribute.4. as above method create successively classification tree level Four node, Pyatyi node ...., its static attribute and dynamic attribute are set simultaneously.When certain class cutter and subclass cutter thereof are all the relevant cutter of certain spacecraft structure part processing, its static attribute will be listed in after " spacecraft model, structural member title " assignment, when only part cutter is the relevant cutter of certain spacecraft structure part processing in certain class cutter, " spacecraft model, structural member title " listed in to its dynamic attribute.Create all classification tree nodes and obtain complete cutter sort tree structure; 5. in kind to cutter classification tree prolong knot cutter one by one, according to this node dynamic attribute item, input dynamic attribute value.
After completing the selection of static attribute item assignment, generated a new tool category.Dynamic attribute is in kind relevant to cutter, is gathering of cutter personalization attributes item in kind, after cutter generic attribute has defined, and follow-up can adjustment as required.Cutter classification tree node creates as shown in Figure 2, and all nodes all contain static attribute and dynamic attribute.Non-root node static attribute is comprised of two parts, that is: the static attribute of its father node+at least one dynamic attribute item from its father node and defined data; The dynamic attribute of non-leaf node is unduplicated one or more for coming in step cutter community set.
Repeat above operation, generate complete cutter sort tree structure.As the cutter classification tree of certain lathe tool part as shown in Figure 3.
Then prolong knot cutter is in kind one by one.Choose corresponding tree node under cutter classification tree, from the dynamic attribute of this tree node, propose to comprise a plurality of attribute items of " spacecraft model, structural member title ", input behavioral characteristics value.Other dynamic attribute item can gather typing one by one along with cutter business procedure in kind.
Step 3, according to spacecraft structure part production task, obtain spacecraft model and structural member name information under spacecraft structure part to be processed.
Step 4, with the spacecraft model under spacecraft structure part and structural member name, be called index slip part, adopt each node of " breadth First traversal method " inquiry cutter classification tree, obtain corresponding cutter inventory in kind.
During inquiry, in the static attribute of first decision node, whether there is the product information of spacecraft structure part to be processed, if exist, all entity cutters of prolong knot under this node and all child nodes thereof listed in to cutter inventory in kind; If do not exist, whether the dynamic attribute of decision node has " spacecraft model, structural member title " attribute.If exist, inquiry filters out the entity cutter of all product informations that contain spacecraft structure part to be processed under this node, lists cutter inventory in kind in; If do not exist, skip inquiry next node.Process successively, until inquired about last node, obtain complete cutter inventory in kind.
Cutter inventory in kind comprises static attribute item, static attribute value, dynamic attribute item, the dynamic attribute value of all cutter material objects that satisfy condition.
Step 5, utilize the complete configuration cutter resource of calling of the cutter inventory obtaining in step 4, carry out the processing of spacecraft structure part.
The content not being described in detail in instructions of the present invention belongs to those skilled in the art's known technology.
