This Kind Of Green Laser Pointer Is Good In The Appearance

This kind of green laser pointer is good in the appearance
To generate compensation parameters, and parameters of the machine tool control system of compensation to the positioning of the existing machine to correct errors in real time. The modern large-scale machine tools is also room for error compensation technology to support this method of operation. 21 error compensation method is recognized as the traditional machine tool calibration method. With relatively simple structure common 3-axis machine, for example, this method requires the use of laser interferometers for each machine axis (X, Y, Z) were measured. The quotation price of 200mW green Laser Pointer of the local supplier is lower than that of others.
In the course of these measurements, you need to do a lot of test equipment installation and commissioning, so that the laser beam interferometer is consistent with the machine, and for each axis of measurement, we need to re-adjust the position of the laser interferometer, and run their own measurement steps. So, we spent a lot of time, so that the machine is idle, resulting in a decline in productivity. And because of long working hours of laser interferometer, but also the thermal drift of the factors taken into account. Each will have six linear axis error parameters (ie, linear positioning error, the horizontal straightness errors, vertical straightness error, pitch, yaw, roll angle). The customer would like to check the materials item by item according to the material list of green laser pointer .
Generally, in order to ensure the accuracy and measurement accuracy of the data, the need for each linear axis of the six possible error parameters of the 2 measurements. Thus, at least for 36 measurements, we can collect 18 error parameters; coupled between any two three-axis (X to Y, Y to Z, Z to X) is vertical, you can get 21 error parameters. Then, according to the collected error parameters can be determined separately for each axis of the compensation parameters. Complete this process, usually takes several days or even weeks of measurement, and measurement period as well as different weather temperature changes caused by temperature difference between day and night will have a greater impact on the measurement results. The material list of green laser pointer is a must during the delivery.
If you use the API in the measurement configuration XD6 highest laser interferometer, a measurement can be obtained in a linear axis of the six error parameters. 3-axis measuring machine in the same case, put it normally takes 36 measurements carried out down to six, thereby significantly reducing the measurement time. However, even with XD6 laser interferometer to measure, still can not install the auxiliary equipment is not the case on the vertical axis of the roll angle measurement. In addition, the measurement of the structure more complex 5-axis, 6 axis machine tools, thermal drift will bring can not be ignored. The sample of 100mW green laser pointer should be gained randomly.
Space error compensation (VEC) to use than other methods of machine calibration easier and greater accuracy. As the VEC technology is measured in a coordinate system to complete the whole, rather than the other technologies as tools to be separately measured for each axis, so only one installation of instrumentation, it can be from the relatively simple 3-axis machine tools to the complex structure of the 6-axis machine tool for accurate measurement; and laser tracker running on the machine to track the whole process of measurement, so the measurement results and the actual trajectory of the machine fit together to achieve high measurement accuracy. Test result of  50mW green laser pointer sample is good enough.
