Laser Measurement System Manual In the existing grinding machine of Max Bögl company, two Laser-Scanners of M2D-200/68 have been inte- grated. For protection against water and dust, the Scanners are packed into a protection case with a pneu- matic flap. The Laser-Scanners are mounted at the vertical arms fort he mechanic probes.

Laser Measurement System Manual Mounting of i-Control Picture of the machine Ethernet-connection Profibus-connection Power supply 24 V Scanner-connection Mounting of i-Control The i-Control is mounted directly at the rear metallic wall of the cabinet. This way of mounting makes sure, that the iControl can dissipate the heat directly to the metallic wall.
Laser Measurement System Manual The Laser-Measurement System consists of the following components: MEL-i-Control Sensor-Controller and Data Processing Unit 2 Laser-Scanner in protection case with pneumatic flap Scanner-connection cables Measurement-Software, VNC-Server for remote access Windows-98SE Operating System Power Supply 24 V; 1.5A DC The Laser-Scanners are mounted into a protection case with pneumatic flaps at the right and left vertical arms of the mechanical probes.
Laser Measurement System Manual Scanner cables Pressure control and filter The Scanner connection cables are mounted firmly at the Scanner head. In the power chain of the machine and in the vertical axis, the Scanner cables moved frequently. Therefore the cable is in segments: 2 Motor 8 m segments in the power chain and a 4 m extension cable have been...
Step 2: launch “adjust.exe” from the directory C:\Program Files\MEL. Adjust.exe is a software tool for Angle measurement. When you launch the software tool, the lasers will be on and create a visible red line on the underground. Activate the checkbox Show Values at the lower right side of the screen (screenshot at the right side).
Laser Measurement System Manual launch the “Ausrichten.exe” software tool. When the software “Ausrichten.exe” is active, the laser light will be shining. Have the concrete panel or a test fixture under the lasers, so that the software will show a profile. Check the position of scanner 1 and adjust mechanical position of the test fixture or machine axis so, that scanner 1 has an ideal profile.

RAM. MEL sends on the Profibus busy, until the evaluation routine is active and data is written into a file in the folder “Transfer”. When the file is saved, the signal “done” (fertig) is set active (see description of Profibus in- terface on page 20) MIKROELEKTRONIK GmbH ·...
Laser Measurement System Manual After start signal, the next scann profile is captured. On screen, the progress from hook to hook can be seen, without having false pictures displayed. The checkbox “adjust” switches the permanent update function. When the checkbox is activated, the screen is permanently updated.

Laser Measurement System Manual The profile points are calculated from the junction of straights over the surface (tangent / approximation line). The parallel straight to the straight through P4 gives the point P1, accordingly also the profile points P9 – P6 were found.
Laser Measurement System Manual Functions of Config.exe The MEL Scanner Configuration Tool is used to make the basic adjustments of Scanner parameters Port Mode Port Address Scann range Measurement range Standoff distance Adjustment with the Scanner Configuration Tool is only necessary the very first time. All other adjustments were made in the user interface provided by the application software.
MEL technical support give you clear advice to do so. The result of changing shutter slider position must be checked out thoroughly to avoid any misinterpretation of “improvement”...
Laser Measurement System Manual When set up is finished, exit the VNC software. Leaving the VNC software on the iControl active in back- ground may seriously degrade the function of the recognition software. If you quit the VNC link at the remote PC Client, everything will be fine, but never keep an active communication while the machine is in op- eration! The same applies to the adjust mode checkbox.

The start of measurement is triggered through the NC, accessing the fast digital outputs of the PLC. MEL writes the measured data to file and confirms after end of measurement cycle “data is ready” (Byte 1/ bit Nr. 4 = 1) When the evaluation is active, Bit 3 is been set to 1.
As described above, this feature can be used to verify Laser Scanner function very quickly. M2D-Laser-Scanners are virtually free of demand for service. This means the Scanner itself does not re- quire any maintenance or recalibration. The Scanner is an optical device, like a photo camera: the optical system is sensitive against dust, fingerprints, dirt and specially water.
Laser Measurement System Manual The flap can be opened and closed by hand. The flap can be opened even against the pressure of the pneumatic cylinder. When the prssure is on, the flap should close automatically, when you release the flap, and no “flap open” command is sent.
When the MEL file has loaded, the calibration algorithm calculates the offset values of the Laser-Scanners relative to the tactile sensors. The offset values are saved to the pre-set values of the MEL measurement software, and saved permanently in the Xconfig.ini-File. The STORE CALIB button then is greyed out.
Laser Measurement System Manual The software is located in the folder MEL inside the Program files folder: C:\Program Files\MEL Drivers for USB devices are located in the Win98ENG folder, Base5.cab. In most cases Windows will ask for the “Windows CD”. Then navigate with TAB and cursor keys to the Win98ENG folder and press ENTER (OK).
