A grinding process is classified as creep feed grinding when the cutting depth is larger than the grain protrusion height of the wheel [3]. Compared with a conventional grinding operation, in CFG, the cutting depth is usually above 0.5 mm. The cutting speed also increases up to 120 m/s and the feed rate decreases to values below 240 mm/min.

What is Creep Feed & Profile Grinding and how does it work?
Creep feed grinding results in high thermal and mechanical loads on the component and system components. This challenge must be met by an adapted design of the process control, the grinding wheel, the dressing process, the machine and the coolant strategy. As a rule, this also increases the machine costs.
