Therefore if a smooth surface is the goal Feed rate affects surface finish as well. The pass of each cutting edge as the tool advances creates a "cusp" of its own. Therefore if a smooth surface is the goal then the same value calculated as the limit of the radial depth should also be applied as the upper limit on the inch-per-tooth feed rate of the tool.

  • Grinding Media Wear Rate Calculation in Ball Mill

    In any mill the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball. This is seen to be Kick s law.
