Automated core and cavity design system for mould works using generative method of computer aided process planning _Mursyidah Binti Md Yusof_E3_2017_MFAR
Sejak beberapa tahun kebelakangan ini, pelbagai usaha telah dilakukan untuk menjadikan aktiviti merekabentuk teras dan rongga menjadi automatik sepenuhnya. Tiga kekurangan ketara dalam sistem rekabentuk teras dan rongga automatik sebelum ini adalah (i) arah pemisah yang kurang fleksibel, (ii) ketidakupayaan untuk mengesan dan menjana arah pemisah untuk kedua-dua undercut dalaman dan luaran dan (iii) tiada pemindahan maklumat daripada sistem rekabentuk teras dan rongga automatik ke sistem pemesinan. Bagi mengatasi kekurangan ini, sistem rekabentuk teras dan rongga automatik (ACCDS) dihasilkan. Sistem ini bertindak sebagai satu komponen dalam sistem perancangan proses berbantukan komputer di mana ia mengambil maklumat daripada mana-mana model 3D CAD dan menyediakan maklumat kepada sistem pemesinan acuan. Kaedah penghasilan adalah asas kepada sistem ini di mana model teras dan rongga dihasilkan dari awal. Hasil yang dikeluarkan daripada sistem ini adalah (i) teras, rongga dan teras-sisi bersama arah pemisah acuan dan (ii) maklumat julat sudut bagi sifar perlanggaran antara mata alat dan permukaan bahagian acuan teras dan rongga. Dengan membandingkan ACCDS dengan sistem terkini yang telah dicadangkan oleh seorang penyelidik, penambahbaikan seperti rekabentuk teras dan rongga yang lebih baik dan pengurangan masa sistem komputer dapat diperhatikan. Ini menunjukkan bahawa ACCDS berjaya menyumbang dalam pembaikan sistem rekabentuk teras dan rongga secara automatik. In recent years, many efforts have been made for core and cavity design system to be fully automated. Three profound limitations in the previous automated core and cavity design systems are (i) the lack in parting direction flexibility, (ii) inability to detect and generate parting direction for both inner and outer undercuts and (iii) no information transfer from automated core and cavity design system to machining system. To overcome these limitations, automated core and cavity design system (ACCDS) is developed. This system acts as a component in computer aided process planning system where it takes information from any 3D CAD model and provides information to the machining system. Generative method is the basis of this system where core and cavity models are generated from scratch. The outputs from the system are (i) the generated core, cavity and side-cores with parting direction and (ii) the information of zero tool-face collision angle range of core and cavity mould pieces. By comparing ACCDS with a recent system proposed by a researcher, improvements such as better core and cavity design and the reduction of system computational time were observed. This shows that ACCDS were able to contribute in the betterment of the core and cavity design system in automatic manner
