GRINDING FEEDS AND SPEEDS - ABRASIVE ENGINEERING

2021-11-10  The effect of increased feed rate on the wheel is to make it act softer. NOTE: In cylindrical grinding, for reasons of productivity, the infeed rate is usually set as high as possible and still avoid interference with the required quality of the process. The specifications of the grinding wheel should be adapted to the selected feed rate.

Grinding Parameters. To establish the feed-rate vw, use the specific material rate Q’ w (Q-prime) given in volume of material removed (mm 3) per mm wheel width per second (mm 3 /mm/sec): Q’ w = (feed-rate v w x depth of cut a e) / 60. The following values may help as a starting point. Creep-feed grinding hardened steel: 5 to 10 mm/mm/s.

Feed Rate Calculator - Daycounter

Feed Rate Calculator. When milling or drilling, or creating a tool path for a CNC machine the feed rate must be determined. Materials have rated surface speeds for a given type of cutter. The harder the material the slower the speed. Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated.
