What is a three-coordinate surveyor

A coordinate surveyor is a person who uses a coordinate measuring machine to check and measure the shape and position tolerance of a workpiece.

This work includes:

1, mainly responsible for the three-coordinate measurement of the company's molds, fixtures and related products, filling in inspection records, and generating and filing inspection reports;

2. Responsible for the maintenance of measuring equipment (such as coordinate instrument, 2D projector, calipers, etc.). );

3, responsible for other daily management of the measuring room.

Extended data:

Use and safety measures of coordinate measuring machine

1, untrained and qualified personnel are prohibited from using CMM. ?

2. Before starting the machine every day, check whether the air supply pressure meets the requirements before opening the control cabinet: the air supply pressure is ≥0.65Mpa, and the machine pressure is ≥0.4Mpa?

3. When the height of the oil-water mixture in the triple water storage cup exceeds 5 mm, manual drainage is required. When the air supply pressure of the machine is normal, and the pressure at the triple joint cannot be adjusted to the normal value, the filter element needs to be replaced. ?

4. Coordinate environment: temperature 20 2℃, relative humidity 40-75%. ?

5. The output voltage of the regulated power supply is 220 10V. ?

6. Do not put anything on the machine guide rail. Do not touch the working surface of the guide rail directly with your hands. Before starting the machine every day, clean the three-axis guide rail surface with high-count woven pure cotton cloth soaked in anhydrous alcohol, and then run the machine after the guide rail surface is dry. It is forbidden to clean the painted surface and grating ruler with alcohol. ?

7. The starting sequence is: turn on ① power box; ② Total gas source; ③ cold dryer; ④ air valve; ⑤ Control cabinet power supply; ⑥ seat measuring controller; ⑦ When the operating box light is on, power on the motor (the emergency stop key must be released); ⑧ After the system self-check is completed, start the measuring software, reset the three axes to zero (reset) and "OK", and enter the normal working state after the automatic completion. ?

8. Return to the machine zero point after each startup. Before returning to the zero point, move the probe to a safe position to ensure that there are no obstacles when the probe is reset, rotated and moved along the Z axis. ?

9. When replacing the probe, use the special tools provided randomly, and the probe used needs calibration.

①? When the measuring software is not open, open the software after replacement. This method is recommended. ?

②? When opening the measurement software, the operation box needs to press the emergency stop key switch, and then open the switch after replacement. A probe will appear.

Error message dialog box, just close it (or enter 100.0.0. 1 input error in the URL input field? History view error message), this information will be automatically cleared at the next boot. ?

10, press the slow key when it is close to the sampling point in manual operation. ?

1 1, rotate the probe, check the probe, automatically change the probe, run the program, etc. , to ensure that the probe runs without obstacles. ? 12.？ When the product is programmed or not used, the speed on the operation box is set to 0. ?

12. When the program runs for the first time, the speed should be reduced to 10~30%. Pay attention to whether the running trajectory meets the requirements. ?

13. When moving and placing the workpiece, first move the probe to a safe position, and pay attention to the fact that the workpiece cannot bump against the workbench, especially the guide rail surface of the machine. ?

14. The shutdown sequence is as follows: ① Move the Z axis to the left, front and top of the machine, and rotate the probe angle to A0B0；; (2) clean the workbench; ③ Turn off the base controller, control cabinet power supply, air valve, air dryer, main air source and power box in turn. ?

15, the steel ball that has not been used for a long time needs oil seal for rust prevention. ?

16. When fixing the workpiece with the insert on the granite table, the torque shall not exceed 20Nm. ?

17. If you find any abnormality (except the error message of replacing the probe), please first record the error message prompted by the software and notify Heicks Kang Technical Service Department by fax or telephone. Inspection and maintenance shall not be carried out without guidance and permission. ?

18. Don't install any software unrelated to the three coordinates in the computer to ensure the reliable operation of the system. ?

19, the air conditioner should be turned on 24 hours, and the maintenance time of the air conditioner should be carried out in autumn, so as to ensure the normal use of the three coordinates.
