Semi finishing and finishing of blade
For semi finishing of the blade, a point milling approach is recommended due to the double curved surfaces. This machining process provides for controlled stock and scallop height left for the finishing operation.
Method: Point milling, preparing the surface for the finishing operation
Process: Radial cutting depth of 0.5 – 3 mm (0.020–0.118 in) after the roughing operation
Finishing of the blade
Continue with point milling due to the double curved surfaces. The recommended solution provides a surface finish of Ra 0.4 μm (15.75 μin).
Process: Radial cutting depth of 0.2 mm (0.008 in) after the semi finish operation.
