ABSTRAK

Kertas kerja ini membincangkan pendekatan dalam mengintegrasikan Java dan persekitaran VRML yang telah diaplikasikan dalam mensimulasi masa nyata bagi proses kisar hujung maya. Pendekatan yang menggunakan Routing ini adalah sangat penting untuk komunikasi dan penghantaran mesej antara VRML dan Java. Dalam pendekatan ini, nod Script digunakan bagi memanggil dan menghubungkan kelas Java dengan entiti-entiti yang sepatutnya di dalam persekitaran VRML. Simulasi bahan termesin bagi proses kisar hujung dalam sistem ini dilaksanakan melalui satu kaedah baru iaitu dengan penggunaan nod penaikan bagi penjanaan objek 3D dan nod PositionInterpolator serta CoordinateInterpolator bagi animasi bahan termesin. Melalui kaedah ini simulasi bagi proses kisar hujung dapat dipaparkan secara maya dan pada masa yang sama graf haus rusuk bagi perkakas pemotong melawan masa pemotongan dapat dijana serentak.

Kata kunci: Haus rusuk; proses kisar hujung

ABSTRACT

This paper addresses the approach towards implementing Java and VRML environment for simulation of a real time virtual end milling process. This new method, which uses routing approach, is very important for communicating and message passing between VRML and Java programme. Using VRML script, all the nodes of virtual world are routed to the Java programme. The Java programme then controls the nodes in order to model the virtual 3D model of an end milling process through the Extrusion node and execute the simulation of machining parameters using the PositionInterpolator and CoordinateInterpolator node. This application provides the simulation for geometrical modelling of milling process and analytical modelling of machining responses specifically the flank wear on cutting tool.

Keywords: End milling process; flank wear
