2, start digital control system, under the calibration interface, make the Z1 axle get back to its mechanical zero earlier by Z1 axle absolute zero position.Manually move each coordinate axis, laser spots aimed at the steel plate initial point, under the calibration menu to the coordinate position zero setting of each coordinate axis.At this moment Zhou physical location (comprising measurement data) is shown as 0, clicks " setting initial point " button.Manually move each coordinate axis again, make laser spots aim at steel plate second point, click " setting second point " button, finish the calculating of steel plate drift angle.

3, under measurement menu, press the pading plate button, this button variable color, use "+" and "-" button on the guidance panel to make coordinate axis move to the position that needs pading plate of each appointment successively then, system can be in the measurement data viewing area numbering to current point, calibrated altitude, measuring height and their difference show that it is 0 until this difference that the user carries out the bed hedgehopping operation with reference to this difference to steel plate.The user moves to next some continuation aforesaid operations until the operation of finishing being had a few then.

4, finish pading plate operation after, the user presses the pading plate operation again, this button color restoration is to original color, the user can proceed other operations.

5, the user presses after beginning under the measurement menu measure button, the loop start button of push panel, and system begins to carry out measuring operation, can switch to graphical interfaces Real Time Observation measuring process in the measuring process.

6, measurement is finished digital control system and is generated measurement result MeasureResult.txt file, switches to the flue software for calculation, reads measurement result, carries out operations such as flue calculating.

7, calculated flue after, the user switches to the drawing menu, imports the flue that the flue software for calculation generates, and can check the approximate shape of plate and position, bar number and the numbering at flue place here; If the flue that dissatisfied expert system generates, all right manual interpolation flue is perhaps accurately located with laser head, obtains starting point, and terminal point coordinate increases a new flue then again; If think that the position of flue is reasonable inadequately, can make amendment to flue with the function of selecting flue, can move, convergent-divergent, stretching; At the drawing menu, taken into full account manual function, need can select the flue of processing, can also delete unwanted flue; The drawing menu can also carry out again setting to the flue processing sequence on the figure, and all can be operated manually, and are very convenient, and is quick; After all arrangements are finished, just current flue information can be recorded in the txt document again and go, can directly read in factory interface, then bent plate is processed.It is exactly to show three-dimensional figure that the drawing menu also has a function, and after plate was through measurement, the drawing menu can generate three-dimensional solid figure according to measured data, make things convenient for the tradesman to check, contrast.

8, in factory interface, press the read data file button and select the data file that to process, press then and begin to process button, again the loop start button of push panel, system just begins to carry out process operation, can switch to graphical interfaces Real Time Observation process in the process.

9, if will suspend current processing or process of measurement, then can press the feeding stop button, system is in the feeding halted state.In the feeding halted state, press the loop start button again, processing or process of measurement will continue operation from time-out.If processing or measuring process in, press reset button, then interrupt current processing or measuring process, press the loop start button again after, processing or process of measurement will rerun.In processing or measuring process, revise the feeding multiplying power or the speed that the mode of process velocity can the real time altering operation is set.

10, the dry running speed of user in measuring and processing can be revised under the parameter menu, selects the parameter menu, revises dry running speed and get final product in machined parameters is provided with, and unit is a mm/second.

11, the user can measure and process operation after configuring coordinate system repeatedly, if need carry out the processing of symmetrical plate, then only need measure or the processing menu under press symmetrical plate button and make this button variable color, carry out again and measure and process operation just can be realized measurement and processing to symmetrical plate.Pressing symmetrical plate button once more makes its recovery color will make measurement and process measurement and the processing that returns to original plate.

If the plate of the current plate that will process and last processing is same template, constant owing to measuring file and supporting file, do not need execution in step 1.

There is the function of preserving current location in system, and system's normal shutdown is again after the start, use " coordinate setting " function at calibration interface to make system motion to initial point (0,0) position if laser spots and steel plate initial point coincide, does not then need to re-execute the calibration operation of step 2.
