In today's booming modern manufacturing industry, it is necessary to reduce costs by quantity, and to win the competition by quality. In aviation, aerospace, automotive, mold and many other fields, higher and higher requirements are placed on machining accuracy and efficiency. Many companies are equipped with three-coordinate measuring machines for quality control. The automatic measurement using the probe on the machine tool can facilitate the installation and adjustment of the workpiece, reduce the number of workpiece handling and loading and unloading, greatly shorten the auxiliary time and improve the production efficiency. The CNC machine tool is both a processing device and some functions of the measuring machine. The most obvious benefits are those that do not have the ability to detect. Most modern CNC machines are now equipped with or can be equipped with measuring devices that help with workpiece clamping. If these CNC machines are equipped with a new version of PowerInspect, these measuring devices can also be tested at a small additional cost. ability.
The latest version of PowerInspect, the detection system of DELCAM in the UK, can be used on CNC machines for on-machine inspection systems, in addition to the CMM and many other inspection equipment. This is a good news for all manufacturers who need to produce a workpiece inspection report, equipped or not equipped with a CMM. In addition to being able to continue to support a wide range of measurement devices with powerful features, the new version of PowerInspect runs faster and is more convenient to use, resulting in a more comprehensive and clear inspection report. Now look at the test report is no longer a patent of the testing expert, customizable, graphic and humanized test report is easy to see.
The workpiece inspection can accurately and quickly find the position of the workpiece and automatically set the workpiece coordinate system; the workpiece size detection in the cycle, and automatically correct the tool offset according to the measurement result; the confirmation of the workpiece and the fixture in the flexible machining; the fixture and the rotary shaft Settings, etc.
Achieving on-machine inspection of CNC machine tools can save a lot of time for manufacturers who must provide independent product inspection reports at the customer's request. By detecting directly on the CNC machine, errors can be detected and corrected in time, avoiding the occurrence of errors until the product is submitted to the tester.
Manufacturers who already have suitable testing equipment may feel that it is not necessary to perform on-machine inspection of CNC machines. On the contrary, they will think that some machining time will be lost in the machine inspection. However, if considered from the overall machining process, the on-machine inspection of CNC machine tools has the potential to greatly shorten the delivery time. Because if the CNC machine is not in-machine inspection, when the part is found to have any error after machining, the part must be reloaded back to the machine. Before the modification is processed, the workpiece must be re-clamped. This process is for any part. It is time consuming and laborious, especially for large and heavy parts, it can take many hours to reposition the parts. In addition, if there is any error in the re-positioning process, some new errors will be generated on the workpiece, so that the product inspection and re-processing has to be performed again.
Although the results measured by the three measuring machine are high in accuracy, it is easy to bring about the influence of the reference change due to the need to repeatedly load and unload the workpiece, and ultimately affects the manufacturing precision. Measurements are carried out on the machine using a three-dimensional probe. The measurement accuracy depends mainly on the accuracy of the probe and the positioning accuracy of the machine. The measurement results are not affected by human factors, so that it is possible to obtain stable measurement results with the accuracy required. On a machining center with a positioning accuracy of ±0.003-0.004 mm, the overall accuracy measured by a three-dimensional probe is ±0.005-0.008 mm.
DELCAM is a world-leading provider of specialized 3D CAD/CAM software with more than 30 years of history. Headquartered in Birmingham, England, the company is listed on the London Stock Exchange. Its software products are best suited for the design, manufacture and measurement of products, parts and tooling with complex shapes. They are widely used in aerospace, automotive, marine, Internal combustion engines, household appliances, glass ceramics and other industries. DELCAM is the only software developer in the industry with a large CNC machining center. All software products are rigorously tested in the actual environment, to the greatest extent possible to meet the actual processing needs. Similarly, the new version of PowerInspect is in-service. The function has also been well tested and successfully applied in DELCAM's large CNC machining shop (as shown on the right)!
DELCAM's new version of the inspection system, PowerInspect, is an open inspection software that is not limited by measuring equipment, ie it can be detected online or offline. It can quickly and easily read 3D CAD models of various mainstream formats, and can easily work with the testing equipment of various well-known measuring machine manufacturers, and compare the inspection data with the ideal CAD model online. The color point cloud method displays the error information and can easily output the test report in accordance with international standards. The new version of PowerInspect not only provides the function of on-machine detection, but also enables the programming of the detection path for the read CAD model before the detection, and the simulation of the detection. The programmed program can then be transmitted to the CNC inspection equipment for automatic detection. At the same time, the preparation of testing procedures can enable relevant personnel in the design and testing departments to work together to improve the efficiency of testing.
A variety of intelligent positioning strategies, especially Best Fit, Free Form and other free form alignment methods, can help customers easily find the ideal CAD model coordinate system and detection model coordinate system.
PowerInspect can provide you with:
(1) Part quality inspection: shape tolerance, surface error, etc.
(2) Assembly inspection: assembly error detection, fixture inspection
(3) Optimization and adjustment guidance: assembly optimization adjustment plan
With good openness, PowerInspect can be adapted to many types of users:
(1) Working online with old-fashioned manual testing equipment;
(2) Working online with old-fashioned CNC testing equipment;
(3) After the transformation of the old-fashioned testing equipment, work online;
(4) Work with the latest contact and non-contact testing equipment to meet the higher requirements of users for detection efficiency and effectiveness.
(5) PowerInspect can now be used for on-machine inspection with the measuring device on the new CNC machine.
On-machine inspection can ensure the processing accuracy, reduce the scrap rate and auxiliary time of the machine tool, greatly improve the productivity, and get the best return on the investment of the machine tool. On the one hand, the price of high-precision CNC machine tools is millions, and on the other hand, the depreciation of machine tools is only about five years. Whether it is improving work efficiency or improving machine tool utilization, it is a boon for manufacturing companies.
The goal of PowerInspect is to minimize the amount of money and time users spend on quality testing!
