Processing of the active measurement Often used in grinding and honing processing, mainly measuring axis, measuring holes and grinding active measurement.
(1) there are two kinds of active measuring three point measuring axis active instrument measuring axis, commonly used in ordinary cylindrical grinding machine.Measurement, hanging out with a press of the hand grinding machine for grinding wheel cover the three point on the active instrument measuring gauge card on the artifacts, in the process of grinding workpiece size change by relay rod by the length of the sensor is converted to electrical signals
(2) active measurement has two point measuring hole and plug gauge type two kinds.Two point are often used to internal grinder, the measurement process and the axis of the same.Plug gauge type is often used in honing and hole grinding.It basically with plug gauge measurement process (see gauge), pneumatic plug gauge hole (see gas measurement instruments) test process is the same, but it has the size will be measured signal automatic display and output functions.
(3) grinding active measure, is used to control the fitting clearance of shaft hole matching artifacts, such as diesel oil pump such as diesel injector nozzle.
Add after active measurement Mainly used in centerless grinding machine, boring machine, precision lathe, and other processing equipment.The workpiece is processed immediately after automatic measurement.When the size change due to the grinding wheel, boring tool, cutting tool cutting tool or for other reasons (see tolerance) warning limits to tolerance zone, the control indicator signal compensation, automatic compensation institution to compensate feed, the deviation of parts within the tolerance zone.The 1970 s saw the emergence of automatic analyzer, it together with the length of the sensor is used for processing after the initiative.It has to rapidly eliminate the gross error and the function of calculation and analysis, such as calculating the standard deviation and the limit error and so on, thus can be issued in a timely manner in line with the statistical law of control signals
