On the Deep Small Hole Machining Method of Nickel-Based High-Temperature Alloy
In this paper, a machining method of deep hole on the nickel-based high-temperature alloy using the pulse electrochemical machining is proposed. The effect of five technological parameters on the depth-averaged radial overcut of the hole to be machined in the machining process is discussed; then the mathematical model is built, and the effect of parameters on the overcut is illustrated. The speed ratio is determined to judge the quality and the processing performance of holes. The technological parameters adopted in the experiment, can be used to produce effectively high-quality hole of big proportion of depth to diameter on the nickel-based high-temperature alloy in the machining process.
