1) High efficiency, high precision and easy operation. The measures adopted are precision mechanical optimization design, 32-bit CNC 4 or 5-axis CNC system, linear motor, 3D probe and error correction technology.
2) In the function, including the gear (inside and outside), gear cutter (hob, pinion cutter, shaving cutter), bevel gear, worm gear, worm, screw, convex gear, broach and other rotary parts of the main error Project measurement; shaft part shape tolerance measurement; powerful analysis functions such as contact analysis, process error analysis, root shape analysis, parameter reverse seeking, etc.; can be coupled to the processing system for real-time data communication.
3) In terms of maintainability, it can fault self-diagnosis and network remote fault diagnosis.
4) In terms of scalability, including software upgradeability and hardware upgradeability. Compared with mechanical display measuring instruments, the advantages of the CNC gear measuring center are self-evident, and its qualitative leap is possible for the measurement of the tooth profile of any shape, not just the involute or linear tooth. Profile. The measurement of bevel gear, K worm (hob) and C worm (hob) is proof. CNC Gear Measurement Center provides tools for measuring and controlling nonlinear spiral surfaces
4 Trends and prospects
Since the 1990s, there have been several notable trends in the field of gear measurement technology worldwide:
1) The overall gear error measurement and gear coordinate measurement are combined into one. China has introduced the CZN450 gear measuring machine with both standard worm and probe. The foreign CNC gear measuring center can also give "virtual overall error".
2) The gear measuring center and the coordinate measuring machine are combined into one. The Radiance of TSK Corporation of the United States and the ND430 of Process EquipmentCompany are developed according to this concept.
3) Functional test and analytical test are combined into one. Simplifying gear measurement is a development trend [19], and the gear overall error measuring instrument will be accepted by the world because it gives the gear full information efficiently.
4) Gear processing and measurement are combined into one (integrated). Since MAAG coupled the CNC gear measurement technology on the CNC gear grinding machine SE202E in 1988, the gear-on-machine measurement technology has been commonly used on gear grinding machines. Looking forward to the future, research and development related to gear measurement technology include: gear non-contact absolute measurement technology; gear virtual measurement technology [20]; gear network measurement and diagnosis technology; gear performance virtual analysis technology based on measured results (smart pairing, Dynamic performance prediction, etc.; further development of gear overall error measurement technology (indicator quantification, performance optimization, etc.); intelligent analysis technology of gear error; establishment of gear statistical error concept system and its corresponding measurement technology; gear speed at production site Sorting measurement and analysis technology (currently ITW's Model4823 is 450 ~ 600 pieces / h; the target is 800 pieces / h); precision machinery, optoelectronic technology, microelectronics technology, software engineering and other technologies on the gear meter.
