In the modern manufacturing industry, an indispensable manufacturing instrument is the three-coordinate measuring instrument. The three-coordinate measuring instrument is not only used in the mold manufacturing industry and the automobile manufacturing industry, but also in the research and manufacturing of the aviation industry. Instruments also play an important role.
There are four main components of the coordinate measuring instrument, namely the host computer, the control system, the software system, and the detection system. For the traditional frame type coordinate structure, it mainly includes mobile bridge type coordinate measuring machine and fixed bridge type coordinate measuring machine, as well as gantry type coordinate measuring machine and cantilever type coordinate measuring machine. It can be said that different types of CMMs play different roles in manufacturing.
Aero-engines are the most important instrument components in aviation products, and the three-coordinate measuring instrument is mainly used to detect engine blades and blisks in the detection of aero-engines. The main method of using the three-coordinate measuring instrument to detect the blades of the engine is to first establish a coordinate system for measurement, and of course, the establishment of the method is completed by the industry standard. Next, according to the design requirements, all aspects of the blade body are detected in the same coordinate system, and the detected values are recorded, and finally the measurement results are analyzed with the help of the analysis software of the three-coordinate measuring instrument.
And only using the three-coordinate measuring instrument to accurately detect the aero-engine can ensure the quality of the engine. The engine is the heart of all kinds of machinery. Only by ensuring the normal work of the heart can it bring greater and better power to the machinery.
1. Check the measurement accuracy
For the coordinate measuring instrument, it is necessary to ensure its measurement accuracy, at least it should meet the accuracy requirements of the workpiece to be measured. Otherwise, it was purchased in time and not put into use. In addition, pay attention to the repeatability of the measuring machine when purchasing. A good measuring machine has high repeatability.
2. Check the measurement range
For the workpiece to be measured, it is not necessarily the entire workpiece. Therefore, when choosing a measuring machine, it is necessary to ensure that the measuring range of the measuring machine can cover the part to be measured. In addition, it is also necessary to consider whether the workpiece can be installed on the machine. It is a good idea to select the measuring range according to the size of the workpiece.
3. Production depends on the type of measuring machine. According to the degree of automation, measuring machines can be divided into two forms: manual and automatic. We should choose the appropriate type according to our actual situation.
4. Check the measurement software system. The advanced measurement system can guarantee a stronger measurement function, which can ensure that the measurement process is faster and more convenient.
The three-coordinate measuring instrument can be divided into manual three-coordinate measuring instrument and automatic three-coordinate measuring instrument according to the operation method, and each kind of three-coordinate measuring instrument has different series, and different series of three-coordinate measuring instruments are used in different ways. The following are some common operation methods of the CMM:
1. Preparation before measurement:
a. Check whether the air bearing pressure is sufficient
b. Install the workpiece
2. Probe selection and installation
a. Install the appropriate probe on the Z bearing connector
b. Check whether the Z axis will automatically slide down (otherwise, the red pressure balance adjustment valve should be adjusted)
3. Measurement operation
a. Turn on the power of the processor
b. Turn on the printer switch
c. Refer to the operation manual and select the command of the required function
4. Notes after completion
a. After the Z axis moves to its original position, lock it
b. Move the X and Y axes to the center and lock them
c. Turn off the power supply and pressure valve
d. Remove the probe
e. Make proper maintenance
