ABSTRACT This paper presented investigation the effect of machining for different strategy on surface roughness and time consuming machining after the free form surface milling simulations based on machining the blade of steam turbine. The first stage of 5-axis milling simulations maching for steam turbine blades were performed using CAD (Catia) / CAM (Delcam) software. The accuracy of obtained allowance is defined as a difference between the theoretical surface of work piece element (the surface designed in CAD software) and the machined surface after a milling simulation. The difference between two surfaces describes a value of roughness, which is as the result of shape on the machined surface. An accuracy notifies a surface quality after the finish machining. The usage of these CAD/CAM software can reduce a time design of machining process for a steam turbine blades sculptured surfaces milling by a 5-axis CNC milling machine with allowed to perform the item on a milling machine in order to measure the machining accuracy for the selected strategies. |
