without any action roundness in grinding

Dec 15, 2000 Centerless grinding workblade angles range from 0 to 45 degrees. For most centerless grinding applications, a top blade angle of 30 degrees seems to provide the best results. The basic rule is the steeper the angle of the blade the faster the rounding action

    In-process measuring method for the size and roundness of

    On-line metrology is widely applied in manufacturing which not only contributes to improving the working efficiency but also helps to ensure the surface quality of machined parts. However, for cylindrical workpieces with discontinuous surface such as spline shaft, the accurate measurement method is still the key challenge. This paper proposes a novel in-process measuring method of geometrical

    Dec 14, 2007 By the time a part arrives at a grinding shop, it has undergone milling, turning, heat treating and other operations. Each completed process adds value to the part, and each may have taken longer than expected. That hurriedness, coupled with nano-level roundness requirements, is enough to make even Type-B personalities at grinding shops panic

    Jun 02, 2008 A line or figure is fitted to any data such that the sum of the squares of the departure of the data from that line or figure is a minimum. This also is the line that divides the profile into equal minimum areas. Out-of-roundness is then expressed in terms of the maximum departure of the profile from the LSCI, the highest peak to the lowest valley
