"Paper ini menggambarkan pengembangan dari penggabungan generasi 5-axis NCpostprocessor dan NC-simulation. Penggabungan ini dibuat sedemikian mungkin pemanfaatan secara penuh kemampuan dari NC-postprocessor, NC-simulation dan mesin milling 5-axis. Selama NC-postprocessing, NC-simulation mengecek secara bersamaan antara posisi alat selama collision dan jika ini terjadi kemudian NC-postprocessor secara tiba-tiba mencari beberapa alternatif tanpa banyak campur tangan operator. Dalam pelaksanaannya metode pencegahan collision secara otomatis mencari kombinasi alternatif dari hasil posisi sumbu mesin yang sama dengan lintasan cutter, alternatif posisi ragum diatas meja berputar dan memanjangkan alat.
This paper describes developments a generalised five axis NC-posprocessor and a NCsimulation package have been integrated. This integration makes it possible to exploit fully the capabilities of the NC-posprocessor, the NC-simulation package checks each tool position for collision and if this latter occurs, the C-postprocessor immediately looks for alternatives without any operator interventions. The implemented automatic collision avoidance methods are searching for alternative combinations of machine axis positions yielding the same tool orientation, alternatif clamping positions on rotary tables and tool lengths."

"Tabrakan atau benturan merupakan fenomena yang sering kita jumpai di kehidupan sehari-hari. Kesan pertama melihat tabrakan atau benturan adalah sesuatu yang memiliki sifat negatif karena ia merubah bentuk, merusak dan sangat memberikan dampak. Eksperimen benturan merupakan usaha untuk mencari sisi positif dan sistem pada tabrakan. Eksperimen benturan kemudian menghasilkan tumpukan, pergeseran, pantulan, jalinan dan lindasan, dimana hasil-hasil eksperimen tersebut kemudian diterapkan ke pencarian isu konteks dan program ruang, hingga didapat ruang seni pertunjukan sebagai konten utama. Pada proses desain ruang seni pertunjukan juga diterapkan sistem-sistem yang terdapat pada benturan untuk mencapai kualitas ruang benturan yang sesuai dengan konteks dan juga membenturkan karakter original dan futuris. Sehingga ruang pertunjukan yang dihasilkan merupakan rancangan ruang masa depan, namun juga tidak meninggalkan karakter original yang dimiliki.
Collision is one of phenomenon which we usually meet in our daily life. First impression about collision is a thing which have a negative nature. The negativeness is because collision can changes an object form, collision can destroys an object and collision can gives a strong effect. Collision experiment is a way to research about positive things from collision phenomenon and the system behind the collision result. Then, my collision experiment can produce drifting, thrusting, reflecting, plaiting and crushing. Collision experiments are carried out to looking for an issue in site and room programming, until I get performing art space to be my point keyword for my design. In process of designing my performing art space, the system of collision also conduct to reach the collision quality space based on site. Beside that, I collide originals and futuristics character in order to make a futurist performing art space based on collision which have modernity but still have the character of original or traditional itself."

"Deceleration rate, time to collision and impact speed have been commonly employed as accident risk indicators. However, it is hard to assess the level of accident risk since these indicators have not been developed with measurable score criteria. This study focuses on the determination of measurable risk indicators which could be used to assess accident risk level and to determine more appropriate accident risk management strategies by using the descriptive qualitative approach. The data were collected from a braking maneuver test conducted on a dry and level closed circuit course. Risk was a function of accident probability and its possible consequences, while accident probability was determined based on the safety factor, i.e. the ratio of available stopping sight distance (ASSD) to minimum SSD (MSSD), which was used to determine the margin of safety. Subsequently, accident consequence was determined using the impact speed at a predicted point of collision along the braking distance path. The results show that accident risk could be easily determined using the proposed indicators, whilst an objective and appropriate accident risk management strategy could be determined based on the minimum margin of safety value which could be obtained from each risk exposure."
