Basic what happens. Is with longer on time duration (pulse) you get higher burn rate. But a correct balance of on and off times is how you keep from wearing the electrode more than the part.
Background: PRI = Pulse Rate Interval. PRI is a term used in Radio Frequency (RF) systems. Specifically, Pulse mode RF systems, as apposed to continuous wave (CW) systems. Each pulse has an on period, pulse width (PW), and an off period. PRI is the time from the start of one pulse to the start of the next pulse. For example, if a pulse on time is 10 microseconds (uSec) and the off time is 90 uSec then the PRI is 100 uSec. Answer: A staggered PRI does not have a constant on and off time. The off time varies.
what is the purpose of edm
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
The width of a pulse and power are related by a term called duty cycle. Full power means the pulse comes ON and Stays ON continuously for 100% duty cycle. No power means pulse is OFF continuously for a 0% duty cycle. 50% duty cycle means pulse stays ON half the time and OFF half the time. Duty cycle can be used to explain the relationship between pulse and power content.
Pulse-modulation
To calculate the time for one pulse in a drive system, you need to know the pulse frequency or pulse rate of the drive. The time per pulse is the inverse of the pulse frequency. For example, if the pulse frequency is 100 Hz, the time for one pulse would be 1/100 = 0.01 seconds, or 10 milliseconds.
clock is consider every signal time duration (on time and off time period) are must be constant.pluse is consider on time or off time period are same time period or it varies.
