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:
