Precision processing in the electrical regulation control
The control method of high - grade machine tool for precision machining is intelligent control.In machining, the state of edm gap is monitored and judged by computer, and the processing conditions of maximum machining efficiency are selected automatically within the range of stable arc.
The stopping time and lifting condition can be modified artificially, but the main parameters of electric pulse (such as current, pulse width, etc.) should not be modified, so as not to affect the spark-gap of machining conditions selected by the machine.
The required conditions shall be accurately entered when the machine tool selects processing conditions automatically, such as machining area, shape, taper of electrode, scaling of electrode size, shaking mode, roughness of machining surface, etc.The processing conditions selected by the machine tool can generally meet the processing requirements, and the operation is simple, avoiding human intervention in the processing process.It is easier to control the electrical gauge with proper control of the machine tool.
