Arrangement graphics rotating certain Angle. Rotating center near the center is the rectangular roughly value. Material utilization in the current Angle was calculated. 6. Arrangement graphics rotated to another Angle. Repeat the steps of the third part, until Angle reached 180 degrees. Figure 5 shows is the arrangement design results. Graph 5: row kind of intelligent design results. The development of ribbon layout The layout of the shingles rule was integration process in knowledge base level into tool design. This intelligent model function is: select parts location, design azimuth and arrange ribbon work step distance. In order to solve the operational procedures, and the rules should be reasonable and effective formulated. Automatic design module is intelligent model in the most important modules. Artificial intelligence technology has been applied in this module. This model, including the pretreatment module orientating products module and extracted from the product modularization accurate information. In order to modify module generates a model, initial design engineering is modified [11]. The modified module instead of processing module. Figure 6 shows the layout of the model and the algorithm for shingles. automatic ribbon layout design preprocessing 1) determine the position and permutations. Parts The user can use interface to determine some of the preconditioning module parameter. The process can determine the position and other elements, such as: to do together shape and size accuracy, parts and user requirements. 12 Parts in the shape of the intelligent model definition, the results are stored in a knowledge base. 2) get parts precise information. The precise information should get in ribbon layout knowledge base. Useful information including punching accurate information and relative location information. This type of knowledge model of information will decide parts stamping sequence. The design process is the main requirements for the position precision to develop a knowledge model [12]. First, the shape of the parts were divided into closed contour. Outline the number of n K = {k1, k2,..., ki,..., kn} (1) Here the first I ki says parts an outline. The relative relations between all contour contained in the relationship of P. If in contour kj ki and precision, there exists between requirements ki, kj) ∈ (p. P = {...., (ki, kj),...} ki, kj ∈ K, 1 acuities were I, j acuities n (I _ = j). (2) The position precision from P get relevant matrix is: (3) Each type of accurate information through the correlation matrices is preserved in knowledge model. ribbon layout automatic design Ribbon automatic placement design module in the knowledge model is the most important one. In the knowledge model contains a lot of important rules, for example in a single stroke in stamping all the inner contour is better. In the next stage of this section was cut off. Sometimes, if the distance between the stamping point within is very small, some will be moved to outline a stage for machining. If stamping point too close from fractionation point fractionation point, if will need to be changed to the next stage. If there are still not the right size and some point can be moved to the next stage. Repeat the process until matrix of every size between points can be accepted. Intelligent design is the core of the layout of the intelligent model development interference point. [13] Parts were divided into many point blank form. These point name is k1, k2,..., dij kn. Here Kj ki and is the smallest distance between. Matrix critical value is S.
