Freeform surface machining

<p>In <a href="/facts/Manufacturing/3qW7bcdy">manufacturing</a>, freeform surface machining refers to the <a href="/facts/Machining/Yrjfj6IV">machining</a> of complex surfaces that are not uniformly planar. The industries which most often manufactures <a href="/facts/Freeform_surface_modelling/GnoMsksI">free-form surfaces</a> are basically <a href="/facts/Aerospace/T6kTLUyV">aerospace</a>, <a href="/facts/Automotive/fGFKUIlA">automotive</a>, die mold industries, biomedical and power sector for <a href="/facts/Turbine/gqosKCkI">turbine</a> blades manufacturing. Generally 3- or 5-axis <a href="/facts/CNC/B2c7UbaX">CNC</a> milling machines are used for this purpose. The manufacturing process of freeform surfaces is not an easy job, as the <a href="/facts/Tool_path/XPHaqz0p">tool path</a> generation in present <a href="/facts/Computer-aided_manufacturing/gqYHXcK9">CAM</a> technology is generally based on geometric computation so tool path are not optimum. The geometry can also be not described explicitly so errors and discontinuities occurrence in the solid structure cannot be avoided. Free-form surfaces are machined with the help of different tool path generation method like adaptive iso-planar tool path generation, constant scallop tool path generation, adaptive iso-parametric method, iso-curvature, isophote and by other methods. The different methods are chosen based on the parameters which is needed to be optimized.
