The conditions for improving production efficiency and its relationship with measurement engineering are mainly reflected in three aspects, namely, shortening the delivery date, improving product quality and reducing processing costs. This article takes this as an entry point and introduces the development trend of measurement technology in conjunction with the gauge exhibits at the 20th Japan International Machine Tool Show.
Trends in measurement technology
In the past ten years, the progress of high-speed machine tools has been extremely rapid. From the field of measurement, some measuring instruments have made significant progress in high-speed and automation. However, from the perspective of the whole industry, the progress of high-speed measuring instruments lags far behind the machine tool industry, which often results in between processes. unbalanced. Increasing the measurement efficiency and strengthening the connection with other processes to make the flow of goods smooth, is the main issue of shortening the delivery date. Under this premise, looking at the measuring instrument products of this exhibition, we can find that many manufacturers have introduced different products that improve the detection speed, improve the operation performance and diversify the functions. Their common features are to improve the measurement efficiency, many New technologies are also developed around this center.
In order to improve product quality, companies are actively developing high-precision measurement techniques with high reliability. In recent years, with the implementation of ISO9000s and ISO9000 standards, the improvement of the measurement instrument management system is imminent. Unfortunately, there are not many related calibration instruments or standard instruments at this exhibition. At the meeting, some new measurement technologies and key improvement technologies were exhibited. It can be seen that companies are still positive about technological innovation.
Both the user and the manufacturer attach great importance to the maintenance of the instrument. Some of the exhibited measuring instruments are not as harsh as the temperature conditions of the installation site, and some instruments combine the functions of various measuring tools. These new products show that manufacturers are also spared no effort in developing cost-reducing measuring instruments.
Non-contact high speed shape measurement technology
The shape measurement of large parts such as automobile bodies or pump impellers requires the use of high-speed means for obtaining three-dimensional position data. Up to now, the measurement has been mainly carried out using a coordinate measuring machine with a multi-joint or horizontal cantilever type contact probe. However, the contact measurement method will be subject to many limitations when measuring large parts, which is not conducive to improving measurement efficiency. In response to this situation, a variety of non-contact measurement methods have been exhibited at this exhibition to enable high-density and high-speed measurement of the above-mentioned large parts.
Tokyo Precision Co., Ltd. has developed a new type of coordinate measuring machine, which is a movable three-dimensional optical measuring device that performs non-contact measurement using interference fringe images and triangulation. There are three cameras in the machine, which can scan the object position coordinates in the 220mm (longitudinal) × 330mm (horizontal) field of view with a maximum density of 4 points/mm2 per second. The calculation can be completed in 30 to 40 seconds. The measurement accuracy is 60 μm. The machine utilizes a new type of data processing technology, for example, measuring the data of a car door corresponding to 1000mm × 1500mm at a pitch of 0.5mm, including the measurement process, a total of only 40 minutes to complete the measurement operation, and the data Perform analytical processing.
The Comet system exhibited by Tokyo Trade Engineering Systems Co., Ltd. is also a movable non-contact CMM. Although it also uses the principle of triangulation, it can rotate the grating stripe as a measurement index to obtain multiple etc. High line data. This measurement method is not easily affected by the surface state of the object to be measured, and high measurement accuracy can be obtained.
Since the above system can acquire three-dimensional position data on the unit surface, it is possible to perform high-speed detection work as compared with the contact type measurement method. In addition, since non-contact measurement does not increase the measurement force, high-precision measurement of soft materials is possible. The data obtained by such systems can be evaluated against CAD data. Therefore, companies must design processes and related application examples to publicly explain to users.

How to make a request for a custom Container House? What details need attention?
Container houses can be customized and processed according to our needs. Size specifications, internal area divisions, and appearance styles can also be customized and processed. There are many different types of container houses that can be customized according to consumer needs. Custom processing. But how to put forward the corresponding requirements when customizing? What details should be paid attention to when customizing?
The overall design should be reasonable
In order to ensure the practicality of the container house, it is necessary to do a good job in the overall design when customizing the Prefabricated House. The customizable series of products need to take into account the specific floor area, internal volume, how much internal space is required, how to divide the area, etc. Generally, it is necessary to conduct on-site inspections, and to reserve the location of the corridor, etc. If the container house is used in the moving area of the construction site, then it is also necessary to ensure that the corresponding transportation channel is reserved to facilitate the staff to walk back and forth, and also to carry goods, etc., the design It is still necessary to ensure that it conforms to the situation on the spot.
Pay attention to material selection
The customizable series of products include a variety of product types. In addition to container houses, there are also custom container houses, custom light steel villas, etc. It is recommended to pay attention to the overall material of the custom. Different, the service life will definitely be affected as well. Therefore, we still have to pay attention to the specific conditions of its material. Generally, it is recommended to look at the actual product, pay attention to whether the cross section is uniform, and whether the thickness of the steel plate and the thickness of the coating are guaranteed. Moreover, we cannot ignore the details of the supporting frame, connectors and other details. We must ensure that the quality of each component is excellent, so that the container house can be used for a long time and its reliability is guaranteed.
Adjustments to blueprints
Customizable series of products may require multi-layer design, so it is recommended to make a request when customizing, and then the manufacturer will provide us with the corresponding design. If there are certain details that need to be adjusted on the design drawing, it must be completed quickly. Adjust, and then go for post-customization. Manufacturers will have their own design team, and after confirming that there are no problems in the design, they can proceed to construction.
