Cutter radius compensation is the key technology in CNC system and is the data sources and basis of contour interpolation. It is the necessary premise to guarantee the part contour according to programming track and cutter radius to plan the tool center path, especially the coordinates of the joint points. The concept of orientation vector is introduced and a technology of 3D cutter radius compensation based on vector method is put forward. The theory and method of cutter radius compensation in coordinates linear processing is studied deeply. The corresponding algorithm of tool center path for programming contour is established according to the relation between the geometric elements. Simulation results proved that the algorithm is accurate and feasible.

“…4) not only obtains a smooth blade surface, but also shortens the machining time, and, hence, increases machining efficiency. The generic multi-axis postprocessor system proposed by the authors [5,6] is used to convert CLSF file into machine control data (NC code). The NC data depends on the configuration of the machine tool employed.…”

A turbine blade has complex shaped free-form surfaces that can be modelled as surfaces with variable curvature by high-degree polynomials. Industry typically utilizes a turnkey system and special-purpose machine tool to manufacture turbine blades. A turkey system is a closed form design. Users need only input relevant data to this system to manufacture the product directly. However, users are unaware of the internal operation of the system. With rapidly advances in computing technology, commercial CAD/CAM systems can be utilized to design freeform surfaces and generate a tool path for the designed surfaces. This study uses a reverse engineering technology that is used to reconstruct the CAD model for a turbine blade. The prototype is measured by a coordinate measuring machine to obtain the geometrical control data points that are used to generate the CAD model in the UniGraphics (UG) CAD/CAM system. The UG/GRlP (GRaphics Interactive Programming) language is used to generate the cutter location data rather than using the default UG CAM module. A five-axis NC code is acquired by the developed postprocessor and verified by the solid cutting simulation software VERlCUT@ Real turbine blade machining is performed on a table/spindle tilting five-axis machine tool, demonstrating the effectiveness of the proposed approach.
