Computer aided manufacturing got started in 1950s when MIT introduced automatic programming tool ( APT ) language. But ,Computer aided design systems were little more than drafting systems till early 1970. Since the introduction of solid modelling technique and splines ( to be specific Non uniform rational B splines ) in computer aided design ( CAD ) systems , CAD models became more efficient and capable of carrying information required for generating tool paths for CAM systmes. This integration of CAD CAM CNC offered cost effective manufacturing techniques such as high speed machining.
My research "Non uniform rational B spline ( NURBS ) bsed optimal tool path generation for high speed machining ( HSM ) " at University of New Brunswick was focused on CAD CAM CNC integration. According to white paper from Unigraphics Solution around 60 % of the lead time required for tool path generation in mold and die making. Therefore, time required for manufacturing can be significantly reduced if tool path is properly planned. Also, it has direct impact on geometric accuracy and surface finish of final manufactured product.
From this project I got expertise in CAD, CAM ,CNC and tool path planning. Remaining page will explain my skills, experience and university work in the area of CAD/CAM.
