lm style cutlery, a rulesbased automated reasoning suitable razor blades materials. For example, if the final processing of materials for the steel, machine tool jig for good stability, cutlery cantilever structures for short, razor blades materials for WAP25. Rough machining cutlery portfolio optimization Xingqiang rough machining the aim is to maximize the removal of excess metal normally used milling cutter, takecutting approach. Thus, 3D mould Xingqiang the rough machining process, is actually a series of ponents Xingqiang processing. Cutlery optimization is to find a group of cutlery portfolio, allowing for maximum efficiency removal of most metals. Cutlery portfolio optimized basic methods as follows : A. To do some long step into knife in the direction of a group of vertical and horizontal search Xingqiang another entity to form a search layer. B. Derive closed to the contours. C. Calculated between Central and outside the island or islands and the distance between the key that affect cutlery choice geometric constraints algorithm flow As shown in figure 3 D. According to the principle of the merger (adjacent to the critical distance will be smaller than the difference between the threshold) to search layer merger, graphic processing and identifying viable cutlery sets, a processing layer. E. Determine the use of each processing layer cutlery, cutlery Xingqiang processing portfolio. F. According cutlery remended processing parameters (cutting speed, depth and into Xianxiao to speed), the calculation of material removal. G. According to the actual removal of the volume processing layer, the processing time for each processing layer. H. Xingqiang calculating the total processing time and residual volume. I. The overall portfolio of the Group cutlery processing efficiency assessment. J . Repeat a~i until derive optimal mix of cutlery. If time is the goal, called for the entire processing time t Xingqiang shortest portfolio to optimize cutlery. Semifinished cutlery choice The main purpose is to remove semifinished rough machining residual contours of the new warrants. To pletely remove height, depth must be greater than Xianxiao parts of each level to the surface distance x. Its algorithm steps are as follows : Step 1:entity models from parts of two adjacent to the cross section of the surface contours and the corresponding length。 Step 2: The average length of contours。 Step 3:calculate its width。 Step 4 : calculating height floor to the surface of parts to the law distance x。 Step 5 : steps 1~ repeat steps 4, each level of d。
