RESEARCH ON WIRE ELECTRICAL DISCHARGE MACHINING STABILITY BY STATISTICAL ANALYSIS

Abstract

Abstract: A new monitor system of wire Electrical discharge machining is reported. Statistical testing is applied to analyze the normal discharge sequence, which is made up with the time ratio of normal discharge. The statistical analysis shows that the normal discharge sequence of a stable WEDM machining is a stationary process and has normal distribution. Kurtosis of the normal discharge sequence is chosen to judge the stability of the machining process. Experiments show that it can online precisely detect the disturbance during machining process, which is an important basis for the machine control system to adopt proper strategies to improve machining efficiency.

Key words: Kurtosis, Machining stability, Statistical analysis, Wire electrical discharge machining
