Ramp contour toolpath is more favorable than any other toolpaths. Experimentation reveals that zigzag toolpath is more favorable than any other strategies for the machining of turbine blade for minimum cycle time. Actual machining is done to validate the s oftware simulation time. The objective of simulation is to generate the shortest tool - path for contou ring operation. Different contour toolpaths being simulated are 2D, chamfer 2D, Ramp, Remachining and Oscillating. Different toolpath generat ion methods are studied to select the best one to find out optimized cycle time. Both productive time and non - productive time s ( airtime, tool change time) are considered for optimization. Most of the research work is focused on cutter path generation with the main aim on reducing total cycle time. Cutting Parameters used for machining are spindle speed, feed, tool diameter, plunge - rate, and dep th of cut. Different contouring toolpaths are simulated in MasterCAM® prior to machining of turbine blades. Toolpath optimization of turbine blade using MasterCAM® software results in reduction of machining time. This paper presents optimization of toolpath for turbine blades in vertical machining centre (VMC). Contouring operations are generally used for this purpose. Turbine blades are complex shapes and difficult to machine on CNC. Today many industries use CNC machines for production of turbo machinery components like turbine blades, impellers, rotors, propellers etc. ![]() published by seventh sense research group.
