  • Analysis of lead twist in modern highperformance grinding methods

    It is a question whether newer modern grinding methods such as quickpoint grinding and peel grinding could provide twist free topography. According to industrial experience, twistfree surfaces can be made, however with certain settings, same twist occurs. In this paper it is proved by detailed chipgeometrical analysis

  • Gear Flank Modifiion Using a Variable Lead Grinding Worm

    Hence, in this paper, we propose a tooth flank crowning method for helical gears, which uses a diagonal (combined tangential and axial) feed on a grinding machine with a variable lead grinding worm (VLGW) obtained by adjusting the axial feed of the dressing disk with respect to the rotation angle of the grinding worm.
