Automated manufacturing system, new method for detecting the workpiece dimensional accuracy

gSystem Bao-US (Hubei Automotive Industries Institute, Department of Materials Engineering, Hubei Shiyan 442002) Abstract: This article from the automated manufacturing system, the need for testing dimensional accuracy of parts starting towel automated manufacturing system described workpiece dimensional accuracy testing methods and techniques, which include special measuring device , CMM, three-dimensional probe and loop detection technology and robot-assisted measurement technique. Keywords: automated manufacturing systems; workpiece dimensional accuracy of detection; new technology with the automated manufacturing system widely used in all walks of life. Processing quality control,ugg stivali, to prevent waste, increase processing productivity and security processing, automated manufacturing systems and thus the workpiece dimensional accuracy of detection of new technology is more and more enterprises are concerned. 1 Detection of the workpiece dimensional accuracy is a direct reflection of an important indicator of product quality, the general size of the workpiece accuracy direct measurement methods to ensure product quality and manufacturing systems up and running. 2.1 2 special measuring device detection technology in mass production conditions, often the special automatic detection device installed in the machine, do not stop, you can automatically detect the processing of the workpiece size change, and according to the measured The results given the appropriate signal to control the processing of machine tools, such as: transformation cutting, tool compensation, stopped feeding, retraction, and shut-down. 2.2 CMM coordinate measuring machine is an automated manufacturing system of basic measurement equipment, used by the workpiece conveyor system will be installed after cleaning the workpiece with the workpiece pallet sent to the system with coordinate measuring machine. Measuring machine can be programmed according to the prior (or from the CAD / CAM systems) for automatic measurement, ten times more efficient than artificial, and measure the shape of complex surface parts with precision. End of the measurement, inspection and testing can also be sent to the machine control system, modified NC program in the relevant parameters, error compensation machine processing to ensure the system has higher precision. 2.3 The three-dimensional probe and loop detection technology, if the coordinate measuring machine with three-dimensional measuring head installed directly on the machine (such as machining centers), it's like the shank structure and the Arbor, you can load the machine spindle It may also release the tool holder robotic tool changing, measuring movement controlled by the program. In this way, CNC machining centers have become a temporary essentially CMM, the entire system through the measurement module to communicate with the machine tool numerical control system. 2.4 Robot-assisted robot-assisted measurement techniques in the measurement process measurement is the robot coordinate movement is not involved in the measurement process, its task is to simulate the movement of people or sensor measurement tool will be sent to the measurement position, this measurement method has the following Features: The robot can be to the common industrial robots, such as turning automatic line, the robot can complete the loading and unloading work in the measure, without having to specifically set up for measuring a robot, the robot-line has a variety of purposes; In the measurement process by allowing the robot movement or positioning error exists, therefore, the sensor or measuring instrument has some intelligence and flexibility, posture and position can be adjusted and survey work independently. Robot-assisted measurement has online, flexible, and high efficiency,tory burch sale, can achieve 100% of the measurement of parts, particularly suitable for automated manufacturing systems and processes between the measurement process. 3 Conclusion With the integration of automated manufacturing systems, agile,ugg milano, intelligent and direction of globalization, based on neural network multi-sensor information fusion technology, intelligent sensing and detection technologies, automated manufacturing systems will become an important detection research and development.
