Tool Wear Monitoring in Milling Process with Laser Scan Micrometer
Initiatives of Precision Engineering at the Beginning of a Millennium, 2002Co-Authors: Takashi Matsumura, Takahiro Murayama, Eiji UsuiAbstract:An approach is presented to monitor flank wear in milling process with laser scan micrometer. Flank wear is monitored with measuring the change of Cutter Diameter and height. Being performed during air cutting time, the presented approach predicts tool wear process based on monitored data. Monitoring intervals are optimized with estimating prediction error and time loss for monitoring.

Tool Wear Monitoring System in Milling Operation.
Journal of The Japan Society for Precision Engineering, 1999Co-Authors: Takashi Matsumra, Takahiro Murayama, Eiji UsuiAbstract:This paper presents tool wear monitoring in milling process with laser measuring instrument. Flank wear on side cutting edge is monitored by the change of Cutter Diameter; and that of end cutting edge is monitored by the change of Cutter length. Laser measuring instrument measures Cutter Diameter and height of end edge which rotates during air cutting time. The presented approach which measures edge shape directly is independent of cutting conditions and workpiece shape. The accuracy of tool wear monitoring is verified with the effect of extraneous objects and thermal expansion and that of Cutter revolution. The approach can not monitor tool wear all the cutting process and has time loss for measuring. Sequential prediction of tool wear and sequential determination of monitoring interval are discussed to apply the monitoring approach to practical use.

Head-Cutter for optimal tooth modifications in spiral bevel gears
Mechanism and Machine Theory, 2009Co-Authors: Vilmos SimonAbstract:Abstract A method for the determination of optimal tooth modifications in spiral bevel gears based on improved load distribution and reduced maximum tooth contact pressure and transmission errors is presented. The modifications are introduced into the pinion tooth-surface by using a head-Cutter with bicircular profile and with optimal Diameter. In the optimization of tool parameters the influence of relative position errors of the mating gears is included. By using the computer program developed for load distribution calculation, the influence of head-Cutter parameters and relative position errors of the mating gears on tooth contact and transmission errors is investigated. Based on the results obtained, the radii and the position of the circular tool profile arcs and the Cutter Diameter for pinion teeth finishing were optimized. By applying the optimal tool parameters, the maximum tooth contact pressure is reduced by 45% and the maximum angular position error of the driven gear by 60%, in regard to the spiral bevel gear pair with a pinion manufactured by a Cutter of straight-sided profile and of Diameter determined by the commonly used methods.

Optimal Tooth Modifications in Hypoid Gears
Volume 4: 9th International Power Transmission and Gearing Conference Parts A and B, 2003Co-Authors: Vilmos SimonAbstract:A method for the determination of optimal tooth modifications in hypoid gears based on improved load distribution and reduced transmission errors is presented. The modifications are introduced into the pinion tooth surface by using a Cutter with bicircular profile and by changing the Cutter Diameter. In the optimization of tool parameters the influence of shaft misalignments of the mating members is included. As the result of these modifications a point contact of the meshed teeth surfaces appears instead of line contact; the hypoid gear pair becomes mismatched. By using the method presented in [1] the influence of tooth modifications introduced on tooth contact and transmission errors is investigated. Based on the results that was obtained the radii and position of circular tool profile arcs and the Cutter Diameter for pinion teeth generation were optimized. By applying the optimal tool parameters, the maximum tooth contact pressure is reduced by 16.22% and the angular position error of the driven gear by 178.72%, in regard to the hypoid gear pair with a pinion manufactured by a Cutter of straight-sided profile and of Diameter determined by the commonly used methods.Copyright © 2003 by ASME

Effects of Blender Structure and Its Force of Soybean Milk Machine on Soybean Milk Quality
Food Science, 2011Co-Authors: Zhao Si-mingAbstract:A commercial soybean milk machine with laboratory modifications for adjustable heating power and rotation speed was used to investigate the effects of blender structure and its force on soybean milk quality.The results showed that larger angle of blender elevation α provided larger strike force and smaller tangential force,and smaller soybean residue rate and smaller granule size and harness of soybean residue were obtained,which could cause the transfer of more nutrients from soybean milk to residue,the reduction in the contents of protein,free amino acids,total sugars and fat,and the increase in viscosity.Larger axial force resulted in more homogenous stirring of materials and more even temperature distribution.Furthermore,Cutter Diameter showed a significant correlation with the hardness of soybean residue,and the axial angle of Cutter tooth was also significantly correlated with solid content,viscosity,protein content and total sugar content.
