Plant, 1998.40:405 【13JDeanJFDBookofabstrset: 5thintenaat [ona】 con-gressofplantmotecularhiotcgySingapore: KluwerAcademicPublishers. 1997.9ExpressingPatternofCoatProteinGenePromoterfromCottonLeafCurlVirusXieYingqiu, ZhuZhen, WuQian, XUHonglin (InstituteOfGenetics,[link widoczny dla zalogowanych], ChineseAcademyofSciences, Beijing100101) (on the next page 43) Step 5: by the voxel geometry and process parameters. Calculation of the operator in the operator's index value and k value. Drilling is only one feed motion. k = L exploration / drilling feed rate, k = 0. To sum up, the corresponding volume element L conical bottom blind manufacturing feature is drilling, which was expressed as: P * V (。,)・{ VI (population I,[link widoczny dla zalogowanych], ∞)} (4) using the above method, can be individually determine the volume element of the manufacturing features. Establishment of manufacturing feature set. 5 Conclusion In this paper, expanding feature mapping functionality. More in-depth analysis of the feature mapping mechanism. Decomposition using voxel, voxel merging, the free TheM. ethodofManufactureforDFM analysis, process characterization techniques to further improve the manufacturing features automatic acquisition process. DFM-oriented evaluation system, the proposed model based on product features automatic acquisition method of manufacturing feature for feature-based manufacturability evaluation and cost estimate basis.
