Frequency measurement through electric network analyzer for ultrasonic machining of steel

The frequency measurement and controlling were difficult in Ultrasonic Machining (USM) process. It was used to remove hard and brittle materials due to the high frequency of vibrations and abrasive slurry. In the present study was introduced an electric network analyzer was used to measure high frequency during the ultrasonic machining of Eglin steel. The controlled frequency was achieved by coupler and splitter. The machining accuracy was confirmed through tool vibrations. The vibrating frequency was sensed by an electric network analyzer based on the power rating, Material Subtraction Rate (MSR), and Hole Depth (HD). The experimental objective was to find the maximum material subtraction rate, holes depth, and its corresponding optimal frequency was found through the Taguchi technique and its effect was confirmed by variance test analysis.
