We, JinYoung, have researched the 3D complex curve processing and 3D curves as well as the 2D functions 
since late 1980s. Not limited to the simple utilization of CAD/CAM, based on the database and trying to express 
the best quality, we are researching each algorithm, as well as compound curves and general curves such as the 
Ferguson spline, Biarc model, B-spline, and NURBS. As the result of such researches, we are producing 
compound curve products such as the turbine blade and vane for the power plant industry, airfoil for aircraft, 
impellers for turbo devices and other compound curve related super precision function gages with our excellent 
technologies in this field.
