Even in the middle stage of the process, there is no way to ensure the high quality of products without an appropriate measurement system. For many companies, the measurement of machine tool workstation is mainly through manual measurement, with the help of calipers, micrometers or indicators. Qualified workers know how to use these tools and can obtain satisfactory measurement results. However, the measurement results depend on workers, who may allow some unexpected errors that will not be recorded. The measurement results are rarely integrated into the computer quality system (CAQ). They record these valuable poems several times, and they also disappear in the filing cabinet. By supporting the evaluation, the whole process above will be more accurate and faster. Fixture hardware manufacturer Hettich (kirchlengern, Germany) is an example of achieving the above goal. They use multi-sensor CMM (CMM) to replace the original manual measurement tools and improve the measurement technology. Several FQ composite CMM equipment from Werth measurement technology channel the original manual workbench to complete the process measurement tasks. At the same time, the company's quality assurance department implements the measurement technical specifications and provides the program structure for the composite CMM equipment. The software of the measuring instrument Parts and main measurement procedures are specially designed for this area. The quality assurance department trains operators and divides the main testing procedures into different parts of the corresponding measurement stage. At present, each measuring instrument has about 1600 measuring procedures. In order to process a large amount of data, these programs are copied back and forth between several measuring instruments. These safeguards enable Hettich to meet high quality standards. Advantages Hettich company reduces the measurement of single parts from 17 minutes to about 2.5 minutes. The FQ CMM equipment using Werth measurement technology reduces the measurement cost of each part by half. All sensors are in the same coordinate system, so the composite CMM equipment can complete the measurement of complex parts in one step. One step solution to process measurement - heitish uses Werth multi-sensor CMM to replace a variety of manual measurement methods. Its strength can be proved by comparison. Its strength can be seen by comparing the actual detection methods of Hettich company. Hettich company produces a positioning hook, which is a multi cut and multi empty stamping sheet metal part. The height of the positioning hook is measured by the inspection gauge in advance. Other relevant features are measured by indicators or calipers, such as positioning hook position. Manual measuring equipment can still be used to measure relevant dimensions in advance. The traditional contact measurement technology takes 17 minutes to measure a part. The traditional multi-sensor measurement technology takes 10 minutes in a measurement cycle. However, Werth's FQ measuring instrument takes half the time and only 5 minutes. In addition, Werth's 'one the fly' process realizes rapid measurement through image processing technology, reducing optical measurement time by 10%. 'Onthefly' process is used for continuous motion measurement, which can prevent motion blur and does not need start and stop time. At present, the measurement cycle of each part of Hettich company is halved, and the total measurement time is close to 2.5 minutes. Combined sensor technology combines optical and contact sensor technology to complete a complete measurement process at one setting, which is not affected by the operator. This technology can measure length, height, empty position, shear model, torsion and bending. The image processing sensor can obtain 60% of the characteristic parameters of the positioning hook. Depending on the gray technology, the camera electronic equipment of image processing sensor converts the optical signal into digital image through the lens. The operator can still see the image through the display. Appropriate software ensures the size and accuracy of the contact sensor, and can display and record. Although the non-contact measurement is realized by using optical telescope, the contact sensor cannot be abandoned. Because optical measurement technology cannot measure some geometric shapes, such as depressions. When the image processing sensor cannot detect some characteristic parameters, the multi-sensor measuring instrument can realize contact measurement under the same setting, so as to realize the scanning of three-dimensional contour and surface. Realize as many measurement points as possible on the horizontal trend and specified path. For the positioning hook, the probe solves 40% of the measurement work. This occupies a considerable part of the whole measurement cycle. 40% of its workload accounts for 70% of the whole measurement cycle. In this regard, the use of optical technology has advantages. The goal of high-quality customers using automatic and fast measurement technology is to further improve the quality of products. The operator first places the parts on the positioning fixture of the composite CMM equipment, and then starts the measurement procedure. The next work is automated, and the operator can know whether to adjust the equipment, which parameters need to be adjusted and how much to adjust through the test report. Multi sensor CMM equipment can even measure complex feature parameters at one setting, because all sensors operate in the same coordinate system. To deal with new parts, simply adjust the measurement program. The setup time and detection cost are greatly reduced. Because, in principle, all components can be measured on the same measuring instrument, and there is no need for special measuring fixtures and measuring tools, and there is no need to manufacture calibration and main components, so the cost of this part can be saved. At the same time, the system outputs the measurement results according to the standard. Hettich found that using multi-sensor CMM technology in diversified component measurement can quickly recover costs. The accompanying quality value and customer recognition will enable us to win more orders, and its value cannot be estimated.
