| 摘要 |
The invention relates to a method of measuring the dimensions of tools and/or workpieces of metal. The measuring is characterized in that an electro-erosive material-machining discharge in a dielectric is used as transmitter of pressure waves, the time of which through the tool or workpiece to the arrival in at least three well-defined positions is scanned and gives rise to time-responsive current pulses for a digital measuring system. |
