Applying pneumatic probe system to monitor part’s surface roughness and grinding wheel’s wear in profile grinding for ball bearing's inner ring groove

The paper presents the results of research and application of adaptive neuro-fuzzy inference system (ANFIT) to predict part’s surface roughness value, part’s oval level value and grinding stone’s wear value in grinding profile for ball bearing's inner ring groove according to parameters such as normal feet rate, the speed of part, the depth of cutting and the number of grinding parts in a grinding cycle. | Journal of Science & Technology 122 (2017) 041-047 Applying Pneumatic Probe System to Monitor Part’s Surface Roughness and Grinding Wheel’s Wear in Profile Grinding for Ball Bearing's Inner Ring Groove 1 Nguyen Anh Tuan1*, Vu Toan Thang2, Nguyen Viet Tiep2 University of Economics and Technical Industries, No. 456 Minh Khai Str., Hai Ba Trung, Ha Noi, Viet Nam 2 Hanoi University of Science and Technology, No. 1, Dai Co Viet Str., Hai Ba Trung, Ha Noi, Viet Nam Received: September 19, 2017; Accepted: November 03, 2017 Abstract The * article presents the results of research and apply pneumatic measuring probe to monitor part’s surface roughness and grinding wheel’s wear in profile grinding for the ball bearing's inner ring groove. On that basis, it makes an online warning for limiting dress grinding wheel according to the given surface roughness threshold or wear threshold. The signals obtained from pressure sensors of pneumatic measuring probe system are processed to calculate grinding wheel’s wear and part’s surface roughness. The output values of this probe system is very close to experimental data values. The results demonstrate ability to monitor the real status of grinding wheel’s wear and part’s surface roughness. Keywords: Profile grinding, online monitoring, grinding wheel’s wear. 1. Introduction of adaptive control and the indispensable components of an innovative and intelligent grinding system. In the profile grinding process, besides part’s surface roughness indicator, abrasive wear and grinding wheel durability are also important technical and economic output parameters. The surface roughness is one of the most important features to assess the quality of product, while grinding wheel wear directly impacts the cutting ability of grinding wheel, productivity, quality and efficiency of profile grinding’s whole process. For profile grinding, area of contact between grinding wheel and workpiece surface is large, thus cutting force and cutting heat are .
