Determination of wheel position in flute grinding of ...

To generate the flute parameters accurately, the wheel needs to be set to a suitable position in the grinder, as shown in Fig. 3, where S r (o r – x r, y r, z r) is the reference coordinate system in the grinder, a x, a y, and a z define the wheel location, and λ is the wheel orientation. Neglecting the wheel rotation around its own axis, the wheel can be seen as being stationary during the ...
