The quality objective of the manufacturing industry is to maintain the production and design requirements of the parts. However, maintaining the consistency of the manufacturing process requires control of the manufacturing process. Establish and maintain the most effective method for the manufacturing process consistency is to accurately measure the workpiece size, the size of the information, data analysis and feedback to the production process, make it become the effective tool for the continued improvement of product quality.
Coordinate measuring machine is one of the most effective methods for measurement and the size of the data, because it can replace a variety of surface measurement tools and combination gauge expensive, and the complex measuring tasks required time from hours to minutes. Three coordinate measuring machine function is to quickly and accurately evaluate the size of the data, to provide the operator with the production process of useful information, which has a great difference with all the manual measurement equipment. Below, we will be on how to choose:
Coordinate measuring machine is used for measuring the workpiece by means of a sensor called a probe. The data obtained can be combined with the description of the size of the workpiece or the feature of a workpiece (such as the hole). By description of these dimensions, it is easier to determine whether the workpiece or feature is super poor. This information also provides clues to correct the aberrations in the production process. Let coordinate measuring machine for your application
If a coordinate measuring machine is what you need to work, how to choose the best? The first to be sure is to buy that kind of model of the three coordinate measuring machine. According to the position of the head of the measuring machine, there are three basic types: vertical, horizontal and portable.
Vertical type coordinate measuring machine is installed on the vertical arm. The measuring accuracy than the horizontal measurement because of bridge structure high confidential, relatively stable and fewer moving parts, making them have better rigidity and stability. Vertical three coordinate measuring machine contains a variety of sizes, can be measured from a small gear to the engine box, and even commercial aircraft fuselage. The horizontal type measuring machine is installed on the horizontal axis. They are generally used in the detection of large workpieces, such as the body of the car, with a moderate level of accuracy.
A portable measuring machine is simplified which cannot be moved to the workpiece measuring machine and assembly parts measurement, portable measuring machine can be installed on the workpiece or fittings above or even inside, this allows for the measurement of internal space, allowing users to measure in the assembly site, thus saving the mobile, transport and measurement of single workpiece the time.
The three coordinate measuring machine to maintain stable, in the design process, usually by increasing the cross-section and structure components to increase the air bearing distance, improve the motor driving force, weight and temperature performance optimization structure based on the material to increase the quality and improve the measuring precision, rigidity, repeatability and measurement of velocity and acceleration. These principles are also applied to some horizontal type coordinate measuring machine, which combines the flexibility of horizontal measuring machine and the high precision of vertical design.
The direction of the horizontal measurement makes the measuring machine is a more reasonable collocation of the horizontal type machine tool. They are particularly suitable for measuring large gear boxes and engine housing which require high precision measurement.
The addition of the turntable makes the four axes possible, and the configuration of the two arms can also be realized, and the various directions of the workpiece can be measured. The horizontal arm configuration is relatively easy to load and unload the workpiece, the small, the workshop type horizontal arm measuring machine is suitable for the high speed production application process. Choose an appropriate machine
Coordinate measuring machine can be selected according to the application of two ways: manual and automatic. Manual machine is the best choice if you only need to measure the geometry and tolerance of the workpiece, or measurement of various small batches of different parts, the manual machine is the best choice. The software of the manual measuring machine can also store and call the measuring procedure, so as to speed up the repeatability measurement. If you need to detect large quantities of the same workpiece, or require a higher accuracy, to choose a direct computer control of the measuring machine. The numerical control measuring machine can automatically detect and eliminate the influence of the operator on the measurement results. Program driven means that the high detection speed can be realized without error.
Tolerance is also very important, manual measurement machine is difficult to achieve a smaller tolerance requirements, and the numerical control measuring machine through its continuous touch to make it more suitable for the strict tolerances of the workpiece with high accuracy and high repeatability requirements.
The numerical control measuring machine, which is used to measure the quantity of the workpiece, is used to measure the geometric quantity of the workpiece, such as the gear, the cylinder, the automobile body and the windshield. For those artifacts that are completely defined or completely unknown in terms of arithmetic, the CAD can provide continuous data acquisition and reverse engineering from parts of the workpiece and model. For very low profile shape workpiece, the scanning probe because of its small scanning plane and requires large amounts of data are defined as the ideal choice.
Measurement of the installation of the site is also very important. Ideally, the measuring machine should be as close as possible to the operator near the manufacturing process to be installed. These workshop type measuring machines generally have a friendly user interface, which is similar to the machine tool control interface.
Different models of the measuring machine can work together. A metering type vertical measuring machine is generally used in the precision metering chamber, as the main arbitration of product performance,
